• Vulnerability ID: NON-2015-0211 on my WNDR4500v3 router

  I use Avast Internet security and he said that my router is vulnerable. I click on details and the ID: NON-2015-0211 shows. How can I fix it? I have already made sure that my router has the latest firmware.

  @wadial Please make sure you have the latest firmware installed and change the default connection of your router password.

  Once done, run the Avast and it should be good.

• WRT54G (version 2) Firmware Version Question

  Hello

  Beautiful room here. I'm glad that this facility exists.

  I have the router WRT54G version 2. Finally, I upgraded the version of firmware years before Cisco Linksys bought.

  A recent announcement by the people of Black Hat (treaties in this article of TechSpot) about their intention to publish a validation tool to exploit a vulnerability of DNS rebinding on a great many routers SOHO forced me to check for the latest update of firmware for my router.

  The interesting thing is that my router's Web interface lists the current version of the firmware as 4.30.12, but the latest version of the downloadable firmware that I see listed on the support site is 4.21.1. I'm not very surprised by this apparent anomaly. If I remember correctly, that firmware version 4.30.12 download is a beta that was supposed to fix a problem connecting WiFi to a certain type. If this version of the firmware was still considered a beta at the time of the acquisition of Linksys by Cisco - or a 'stable' later firmware version incorporating the same or better fixes for the issues addressed by 4.30.12 that had been produced at that time-so maybe 4.30.12 was ruled out.

  If you read the article of TechSpot and the associated table of preliminary vulnerability, test reports, you'll see that router WRT54G version 2 is not specifically listed. Version 3 of the router is listed as vulnerable, and version 5 of the router is not.

  So, my questions are:

  Everyone here is aware of information indicating whether or not the problem of DNS Rebinding vulnerability affects the WRT54G version 2 with the last registered (4.21.1) router firmware version?

  If so, does anyone know if yes or no Cisco plans to release an update for this old router?

  If the router is vulnerable and will not be solved with a firmware update I'll probably have myself a new LInksys router which is not listed as vulnerable. (Believe me, I'm not leaving this thread to bash Linksys. This router ran like a train of 24 hours a day for years without a single hiccup that was not directly attributable to the problems of the ISP. For the price, it's one of the best purchases of equipment I've ever done calculation. And I have done this since the beginning of the 80s when I was using a CP/M system and an Apple / / e.)

  If the 4.21.1 version firmware for WRT54G version 2 is not affected, I wonder if anyone knows if yes or no 'downgrading' of 4.30.12 to 4.21.1 is likely to lead to a failure of the router. (I'll probably try it anyway. If it brick the router I'll just go ahead and get a new one.)

  BTW, I use this router with the ease of remote administration and UPnP off and strong admin password that is changed each week. (When I always used wireless I used WPA2 AES with strong password, but I am all wired now with the systems running Debian testing).

  Forgive me for talking to myself. I decided to just go ahead and "downgrade" of the 4.30.12 firmware 4.21.1 version - just because I prefer to use a version of firmware known and supported for this material. The downgrade has gone well, so no worries about this.

  I'll look for news on whether or not this version of the firmware on this particular router is vulnerable to the flaw in DNS rebinding and acts accordingly.

  Sorry for the noise.

• Best options .vmx and config.ini for maximum security of the host

  Hello.  The most effective way to keep your private data is by keeping it on a separate computer that is not connected to the internet.  Better yet, only transfer files to and from this computer using usb flash drives, not network.  I would do the same thing with vmware player.  The guest would be used for navigation and connected to the internet via a usb cable rather than fill the host's ethernet card.  The host would be the private computer that has a connection to the internet.  It will have all the tcp/ip or other network completely removed features.

  The only means of communication between the host and the guest will be a usb flash drive.  The guest would be without a hard drive, a liveCD of linux, which would only have a disc temporarily when you connect the USB flash for it.  It goes without saying that you should not connect usb flash to the guest after navigation in a dangerous site.  Or even any site unrelated to download just one you want to record to the host.

  But I've heard there are always ways to invade privacy, something to do with the Clipboard, pagefile, exploits, etc., and most can be combated by configuring the .vmx or config.ini for maximum security options.

  Does anyone know what are the options in the .vmx or the config.ini file should be used for maximum security, to complete isolation of the host?

  It is good to hear Hat based project.

  The problem with the on-board unit is often a wrong configuration (such as keeping the default values). These devices can be operated directly from distance or indirectly via a host operated on the local network. Otherwise, the router is vulnerable directly from outside, a host on the local network can for example be targeted by an xss attack that targets more your router. SPI Dynamics from their publication a portscanner of javascript for the local network (search google for it). At www.gnucitizen.org, they have a lot of router base articles (some of them mention mesing with dns via upnp (scary stuff). Some links on this stuff;

  http://SecLists.org/fulldisclosure/2006/Aug/0097.html

  http://www.shoaibyousuf.com/2009/04/ciscos-Linksys-router-is-vulnerable-to.html

  http://www.packetstormsecurity.org/0801-advisories/HomeHub-UPnP.txt

  A misconfigured host on the local network can be devastating too. Remember a few years ago when the DreamBox became popular (it's actually a GNU / linux). No one hardly changed passwords by default and where wide open to the internet on port 21,22,23,80. Now connect to port 22 (ssh), meant you can use it as a proxy in the local network (to log into the router and do whatever, or target other hosts on the lan). Google search for it also.

  On MOA, it didn't is nothing other than a server stripped 2003 running as LocalSystem. It means that it is not patched and can be exposed to exploits more than servers entirely patches. It will, also, a pain in the back to add patches to such an MOU. Ulli you agree? However, given that the system is a version of server, there also fewer services that may be potentially vulnerable to exploits. If you have two vectors in the opposite direction, such a system could be on the vulnerability. To run patched systems entirely in the eye of the ram at http://www.disklessangel.com . By passing as LocalSystem, means that once exploitet, the operator can make preatty although, as opposed to less than a user of privilged in expoitet. Also ongoing execution in a State without drive, limit significantly impact the feat will do for your system (at least to vm (with bootkits in head)) that the malware disappeared on restart. However, if you where exploitet in ram, the attacker could still get all your personal information that you presentation while boot (just like as if you where linking the local hard disk (only difference don't have the disk in the next startup).) Once the network connection is cut off, even attach flash drives, will leave malware what what to do for your flashdisk, as always, there are in ram, expect that connect the disc (but is resolved naturally if reboot before you connect the flash). How would you be able to download and save a file in such a case?

  The next thing to worry about is the type of connection to your router. If through wireless it is a whole new world of expoits (xss for free/airpwn, breaking encryption, mitm, operator chipsets, etc.), so definitely go for ethernet cable.

  The decision of virtualized or not, my vote would go to non-virtual, as there is at least an attack vector less to worry about IE EP-mode pure diskless as MOA.

  BTW, what kind of project is this?

• WNDR3700v2 with Runninng Win10 ReadyShare now get the error "\\Readshare is not accessible.

  I have the NETGEAR WNDR3700v2 with ReadyShare router. Was working fine yesterday. Runninng Win10. Today, after some update and restarting my laptop, from one day to the next, get error message: "\\Readshare is not accessible. You might not have permission to use this resource... "I can access this USB HD on another laptop with Win 10. What should I do to get it back working properly again? Thank you.

  Darryl

  There was at least on Win 10 update overnightt, because my laptop has rebooted. But a few days ago the Readyshare started working. Funny, that was my 2nd laptop Win10 could still access ReadyShare. Mayby another update on my first laptop caused the problem. Today he's back to working perfectly again. Thank you.

• Wireless does not. model wndr3700v2

  We have this router and this is the kind of old... 2011 model wndr3700v2. We have never had any problems with it until tonight. It says 'unavailable internet for netgear' my phone connects to the internet, but a few seconds later, it says not available. All the lights on the router appear to be right. Anyone know what could have happened suddenly to stop work and how to fix it? Help, please!

  Yes when I called support, they said it was probably a problem with my IP instead of my router. I don't know if it was just the weather or what, but we have had this problem for 3 nights in a row, and all 3 nights, we had rain, wind, etc. And since then it has been fine. I have a desktop computer but is not a wired connection, they are at different levels of the House. All wireless connectivity to him down/did not, and the next morning would be upward. And since we have never had any problems before, I guess it was because of the weather... Although at the time where I just thought our router has out or loss of connection. I appreciate the suggestions and help, but I think this is resolved! Thank you!

• How can I secure my laptop when I surf the internet via a public router at work?

  How can I secure my laptop when I surf the internet via a public router at work? I mean if I use a router to work and others use too and I use a private laptop! I heard that someone hase the knoladge he can enter my laptop the couscous that he uses the same router I do. you have a special program for that, or is there a place in my computer that I need to enable to avoid the unwanted entries?

  If your Windows is updated and your Windows Firewall is enabled and that you have updated anti-virus, that would be fine. In Windows 7, you must check Action Center in Control Panel to see your security status, if something is wrong that it will show a message in Windows XP and Windows Vista, he calls the center of security.

  They may only enter your laptop or hack, if your firewall is disabled or there is a vulnerability in your system or a Malware would cause of vulnerability, and in all cases to ensure that your Windows updates and anti-virus is running, you are protected.

  Another thing is that if your router requires the password, then choose strong password and change it regularly, if it is public without password or authentication, then you need to careful when visiting Web sites because they could be monitor and publicly display information. Some websites have encryption that in Internet Explorer, it shows as a lock icon pad indicating that your transaction is encrypted and you're safe.

  It depends also wireless encryption in your company that will be in service by admin or SOUND Department if it's WPA2 which is good but for WEP or WPA, you should be very careful. I suggest to discuss this issue with your COMPUTER service too.

  Hi Virginia,

  Thanks for posting your query in the Microsoft Community Forums.

  After the description of the problem, I understand that you can not connect to a wireless network on windows vista computer.

  I appreciate your efforts on this issue, however no need for you to worry we are here to help and guide you in the right direction.

  Help me with the information below.

  -Don't you make changes on the computer before this problem?

  I suggest you to disable temporarily security software and then check if you are able to connect.

  Method 1

  You can also temporarily disable the security software and check if it works.

  http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Firewall-on-or-off

  http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software

  If disabling the security software solves the problem, then contact the manufacturer of the specific security software to fix the problem.

  Important: These steps may increase your security risk. These steps may also make the computer or the network more vulnerable to attack from malicious users or malicious software such as viruses. We recommend the process that this article describes to enable programs to operate as they are designed for, or to implement specific program features. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular environment. If you decide to implement this process, take additional measures to protect the system. We recommend that you use this process only if you really need this process.

  Method 2

  Reset the router and see if that helps.

  Note: to help you reset the router, you can consult the manual that came with the router or the router contact manufacturer.

  You can see this help article.

• E2700 cannot connect directly to the modem, but connects via another wifi router?

  I have a Netgear WNDR3700v2 that I was very pleased until I had a nest of thermostat. Apparently it's a router not supported and I had to change it. I bought an E2700 since he took charge, but I have a huge dilemma...

  If I connect the linksys directly to the modem, I don't get an internet connection. I got out and renewed IPs without success...

  But if I wired the linksys for the netgear, I get a good solid internet connection. problem is, I have no need for installation of 2 routers on top of each other...

  any suggestions? I would like to know what kind of information you need.

  Basically, I do not understand why he is not able to connect directly to the modem to linksys. Yet, it becomes solid connection wired through another router.

  I use Comcast and South FL. it is motorola surfboard modem

  OK, found the solution.

  call 1800COMCAST

  go to the problems of the internet, there is an option to send a refresh signal to your modem.

  I did, and it started working. I guess that clears the memory and binds to the new MAC address...

  After that I did, internet is back. I hope this will be useful to someone. I was ready to return the dang thing.

• Router (wrt300n) acting as a forwarder/server/resolver dns, why/how?

  Hello

  Modem speedtouch 516 defined as = bridge

  Router = linksys wrt300n, made the pppoe dsl connection

  OS = vista 64-bit, also have test with computer laptop linux clean/white

  By making a few landmarks on the dns servers, a tested program 192.168.1.1.

  This made me nervous and start questioning why is this and is there a problem of problem/vulnerability/security/etc.

  192.168.1.1 is my default gateway so my router.

  Do a "nslookup - 192.168.1.1' (temporary use this specific ip address as a server) and then by typing a url returns a response.

  According to tech-live chat, this router does not have dns forwarding nor made any linksys router.

  If the router doesn't do not dns forwarding how is, I get dns results when you do a nslookup or change the dns at 192.168.1.1?

  On some tests (dnsbench of grc.com) 192.168.1.1 is faster than dns servers that my ISP router forwards/gives. If the router was dns, it would normally use the dns ips he has in his list given to him by my ISP, right? So 192.168.1.1 and ISP - dns speed should be the same speed, no?

  Am I lack/misunderstanding something?

  Help. Thank you

  1. If the beneficiary address DNS server to the client is 192.168.1.1 router must do DNS redirection. Otherwise the customer could not resolve host names. There is no other way to do this if the client knows nothing but 192.168.1.1.

  2. the router uses the servers DNS ISP as shown on the router status page. Here are the only addresses that the router knows.

  3. the router is probably a DNS caching, also, so the router's responses are faster if the result is in the cache.

  4. as it is a redirector is also vulnerable or not vulnerable to the poisonings and other things your ISP DNS server.

  5. you can not handle. This is a redirector maybe with a bit of cache memory.

  6. If you set like him your other DNS server on your customers or in the DHCP server.

  Hello

  -What is the security software and firewall program you use?
  -Are you having the same problem if you try to connect to the router via a cable?
  -You are aware of any changes made on the computer before this problem?
   
  Method 1: Temporarily disable firewall and third-party software on the computer for a test.
  http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Firewall-on-or-off

  Note: You should not turn off Windows Firewall unless you have another firewall is enabled. Turning off Windows Firewall may make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.

  Disable the anti-virus software and try to install the updates.
  http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software

  Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

   

  Method 2: Clean Boot Mode

  I suggest to maintain the computer in clean boot mode and check if the problem persists.
  A clean boot to check if startup item or services to third-party application is causing this issue.
  You can read the following article to configure the computer to boot:
  http://support.Microsoft.com/kb/929135
  Note: After the troubleshooting steps, see step 7 in binding boot is a way of putting your computer to normal startup mode.

   

  Method 3: If the problem persists, I suggest you run the hotfix mentioned below link and check if that helps.

  You cannot connect to a wireless network on a Windows Vista-based computer

• My HP desktop computer can not find my router wireless already in line with the other 2 computers. Help?

  Vista HP Desktop shows cable with a new Linksys E1200 as connected to 'Unidentified network', 'Local' only without an internet connection.  Same computer, same Ethernet cable connected directly to the ISP modem works fine. Router has been implemented by drive and works very well for a 2nd office direct by cable and wireless laptop.

  Use exhausted with Cisco and they believe that there may be configuration problems they can not help me solve.  Map network shows "works correctly. With current Ipv4 set to auto configure I get very little connectivity at startup until the weather window says service not available.

  Can someone help me to get these two talking?

  Hi FrankeyeAm,

  ·         Did you do changes on the computer before the show?

  ·         You get the error message?

  Follow these methods.

  Method 1: Temporarily disable the security software.

  Disable the anti-virus software

  http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software

  Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

  Method 2: Follow these steps:

  Step 1: Start the computer in safe mode with network and check if the problem persists.

  Startup options (including safe mode)

  http://Windows.Microsoft.com/en-us/Windows-Vista/advanced-startup-options-including-safe-mode

  Step 2: If the problem does not persist in safe mode with networking, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

  Note: After completing the steps in the clean boot troubleshooting, follow the link step 7 to return the computer to a Normal startupmode.

  Method 3: Follow the steps in the article.
