  How the router can understand protocols such as SSH or telnet
  and device for layer 3 router

  second question, I found this accessory of CCNA security book Keith Barker
  wrote it router look at application layer information how?

  Thank you in advance.

  Hello

  I think that confuse you routing process.

  Router; route packages using their layer 3 address.

  This means not router cannot understand the upper layer protocols. There just transmission by addressess of layer 3.

  for example: we can define Access-list for tcp and udp layer 4 packets. router can decide whether to permit or refuse even if these lists filter by glance in the section layer 4 of the package.

  In an SSH or Telnet session, role of the router is terminal.

  Intermediate device belongs in the the router routing process.

• Firefox prevents the connection from the router

  WRT120N router Linksys-Cisco, Firefox 22.0

  I discovered that my router rejects all attempts at connection (192.168.0.1, 401 authentication failure "browser can not perform authentication or authentication failed") when you browse to it from Firefox. It allows the connection when the attempt is made of Chrome.

  I remember having long ago something similar with Firefox, but resolved by disabling the option "say it me not to follow the sites", following what connections made; just looked and it is still not verified - if this isn't it.

  I looked a the packet capture and the password IS sent to the router, but it rejects the connection.

  Any ideas?

  "BUT IT WORKS CORRECTLY BOOTED IN SAFE MODE."
  Which prompted me to check the extensions.
  I called, guess what... TAKE STEPS TO TRACK ME.

  (Why is there such an extension if it is built in function?)

  Disabling, allowing the router to connect! I don't know why twice now, try to activate Do not not track eliminated the possibility to connect to the router... but this is the solution.

• When I try to connect with my wireless laptop will connect only to Local access. If I connect the laptop to the router with the ethernet cable, it works very well.

  VIsta - Local access only

  HI -.
  I recently moved.   I use the same router from my old apartment and I had no problem connection in the past.   Since I moved I have a new Time Warner modem (Cisco) and the modem works fine.

  The router also works very well I'm able to connect with my iPhone and IPad without any problem.

  But when I try to connect with my wireless laptop, it will only connect to Local access.    If I connect the laptop to the router with the ethernet cable, it works very well.

  It's a Dell Studio 15 with Vista.

  The computer is able to connect to wifi to other places without any problem, but for some reason that I can't connect home.   I tried to reset the modem and the router several times, but that did not help.   I tried the option repair & diagnose several times but it doesn't work.

  I tried to look for other solutions online and tried to disable IPv6, and while it helped some and I was able to connect wireless, the computer ran so slowly that it didn't seem like a good solution.

  This has been very frustrating.   Thanks in advance for any help or suggestion.

  Hello Staciusa,

  Have you tried to change the wireless channel that your router is running at? There may be interference that could prevent the internet connection:

  Take a look at step 6 in this article that give more details about it:

  http://www.Microsoft.com/athome/Setup/wirelesstips.aspx

  If you need assistance to change the settings of the specific router, you will need to contact your router manufacturer or your internet service provider.

• WRT110, Vista, wired desktop cannot access utility based on the router's web

  Computer Vista hard wired to the WRT110 cannot access the router. But it CAN get to internet and CAN ping router without losses. The XP machine is wireless, can get internet and CAN ping router without losses, but also can NOT access the router page. Ipconfig displays 192.168.1.1 is the correct default gateway address.  Yesterday, I had to reset the modem to access the router and had to enter all the parameters.  Could access router yesterday but can't today. The IP address is valid from yesterday to tomorrow. I don't understand what has happened to prevent access to the router. I even unplugged the modem to the router and still cannot access router today.  I can't find this problem in the forum, hope this isn't a duplicate request. Thanks for any help

  I have NO idea why, but I can access the Web with IE8 installed utility pages.  Has absolutely no sense to me.  Of course, it must be some kind of safety but my IE use medium-high settings, so I can't imagine what passage of IE7 to IE8 did indeed these parameters.

  Happy now that I can access these pages, finally.  Hope this helps someone else.

• Access to the network of a device ethernet via the ports of the router.

  I was wondering if someone can help me with a router configuration. I have an ethernet device, a built-in Digi Connect me stack ethernet. I put the IP, subnet, gateway, etc. on this device. It has a serverver web and telnet and FTP features. What I want to do, this is the device connected to a WRT54GS router to one of the ports on the back. Then I want to connect internet routers connecting to my local network. On the LAN, I have a PC I want to use to access the web page of the Digi device through the router. The LAN has affected the PC an IP address of 3.11.201.33 and assigns the router IP Internet of 3.11.201.32. The PC is set to dynamically set an IP address. I have configured the Digi device to have an IP address of 192.168.1.100. I want to open a web page on the PC and connect a digi device. I can't get this to work. I tried to add the IP address of the device Digi to the DMZ on the router, but that did not help. How can I get from the PC via the LAN, through the router, on the port that is connected to the Digi? Any help is apprecieated!

  Outgoing FTP for multiple devices behind the router need not any special installation... you will not need to pass all the ports for that.

  You can port forward more than a device with the stock firmware digi... I just forgot how port forwarding 'niche roles' it is on the page... the WRT54G V5 has 10, so assuming that no other device in transmitted port, you should be able to forward the ports ftp and telnet for 5 devices.

• Router WRT160N v2 lose wired connections have to restart the router, then all is well again.

  Hi all...

  I'm having some trouble with my WRT160N v2 router, now I use it only to share the internet connection between wired PC.

  I have tride (with the help of live chat) to reduce the size of the MTU to 1300, with no success, also an update of the firmware was informed, but I can't find an update for the version "v2" of the WRT160N router.

  The behavior is really funny:

  -Get random msgs "cable network is disconnected" and "local network connection is now connected".

  * plugged direct cable from my modem to the PC then there is no problem, me makes me believe cables are ok

  -Some sites don't be loading not on two PCs connected to the router, Firefox and IE8 trough during live chat, confirmed the site is up, it's as if something is stuck in the cache of the router or something that prevents some loading sites, sites that happen are random, the browser are not even a real attempt to connect but go now empty.

  -Repair windows and hollow EasyLink advisor will have no effect, Easylink advisor indicates that the connection is good when it doesn't appear, restart the router is always fix the problems (for a while)

  Modem: Comcast Cable

  Router: WRT160N v2

  PC1: XP Pro SP3 connected cable trough using Avast 4 Pro Security

  PC2: XP Pro SP3 connected hollow cable using Outpost Security Suite Pro 2009

  It's very frustrating because you can imagen, I hope someone got some clues for me on this one...

  Thanks in advance...

  Martijn greating

  It should list version 1, 2 and 3, when you go to: http://www.linksysbycisco.com/US/en/support/WRT160N/download

  Here are the instructions to DOWNGRADE the WRT160N V2, DO NOT USE this on VERSION 1 or 3, it will turn your router into a door stop!

• I have a Wireless N card and the router, but only to connect to wireless-G speeds

  I just got a new HP DV7T with a N (with bluetooth) wireless card: Intel Centrino Advanced - N 6200 AGN

  I use a Netgear wireless router (WNDR3700) double radio.

  My wife's cell phone can connect to the router with a N Wireless card at a speed of 170 Mbps.

  My laptop can connect only to 54 Mbps. I checked that I am connected to radio N of my router (the radio of G/B/A has a separate connection).

  I found a useful post here:

  http://h30434.www3.HP.com/T5/wireless-Internet-and-home/wireless-does-not-seem-to-connect-at-802-11n...

  I followed the advice of responses and checked all the settings of the router (but the success of my wife to connect at speeds N essentially rules on the router) and checked the settings of the adapter to make sure it helped N.

  I wonder what it is that I'm missing. Any suggestions would be greatly appreciated.

  Thank you.

  I was able to determine the problem after extensive web searches.

  I was using the WPA-TKIP authentication which, in some cases, prevents the speed N Wireless.

  Once I changed WPA2-AES authentication radio N I got immediately 300Mps speeds and it varies between 240-300Mbps now.

  I hope this will help others with the same question!

• Must restart the router wireless whenever I start my laptop Vista. __

  I have a Dell Studio laptop 1735 under Windows Vista Premium, Service Pack 2. Last week, all of a sudden it will not identify the wireless network. It will show the connection to the local network, but not the Internet. It seems to be churning out, attempt to identify the network 'Public '.

  If I unplug the router (Belkin Wireless, 2296E1), wait 10 seconds and plug it back, internet is fine. When I turn the machine, no internet.

  • I deleted the network wireless and recreated - no change.
  • I tried to "Diagnose the problem" he tells me to reboot the router.
  • I tried to reset the NIC - no change.
  • I disconnect and reconnect - local, but no internet.

  I've updated the software Dell Wireless. My Windows updates are up to date.

  I have a Windows 7 computer and a MacBook as well - both are very good. That is what it is?

  Hello

  Turn the computer close to the wireless router to compensate for weak or blocked signals that could be part of the problem in the place of work more far.

  In the computer itself.

  Check the Device Manager for the wireless card valid entry.

  http://www.ezlan.NET/Win7/net_dm.jpg

  If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

  Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

  http://www.ezlan.NET/Win7/net_connection_tcp.jpg

  Make sure that if there is Wireless Utility a utility vendor is not running with the native Windows wireless utility.

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Above everything is OK and it connects to the wireless router. Log in from any computer which is, or can be connected to the router with a wire wireless, disable wireless security and try to connect with no. wireless security.

• Customers unable to browse the internet on the router from Cisco 871 K9

  Hello world

  "I just bought my Version of K9 Cisco router 871 running this flash system image: c870-advsecurityk9 - mz.124 - 4.T8.bin".

  Hello

  problem is that you have changed the IP address of the interface VLAN 1 from 192.168.1.254 to 192.168.1.1
  If you need to change by default-router dhcp pool:
  Select conf t
  Richard-Edet dhcp IP pool
  no default router
  default router 192.168.1.1
  end

  NAT is also missing:
  Enable
  conf t
  IP access-list standard NAT
  permit 192.168.1.0 0.0.0.255
  output
  IP nat inside source list NAT interface SA4 overload
  end

  Also perhaps you cannot ping the router console PC because the computer's firewall blocks the ICMP protocol. In windows, I'm sure he is blocked by the firewall. Then you can try ping 192.168.1.1 from the PC and it should work.

  Try above changes and then write me if it works, or so we can make other changes.
  You can also post the output of the commands (if this will not work):
  router: ip road show
  router: ping 8.8.8.8 (it should work if your internet provider doesn´t blocks the ICMP protocol)
  PC: ipconfig/all

• Not to get the IP address of the DHCP server on the router

  Hi, I had a problem in the last two days with my internet Setup. I search the Web and a few problems to be 'similar' with solutions that do not work for me.

  I have a PC desktop (Dell 5100) connection to a router Netopia broadband via a cable (Intel Pro/100 VE overcards nic) who does not receive its IP address (192.168.1.x, is that DHCP should be dishing out) since the DHCP service on the router, as it is supposed to. Gets a 169.x.x.x IP address-, in my view, it is a distributed IP address when no DHCP service is. No amount of restarting and reinstalling the cables has helped. I also have an older router which allows to connect via the USB port, who assigns a virtual NETWORK adapter, and that gives me the same result, i.e. 169.x.x.x IP address.

  I also have a wireless connection on the Netopia Router that I can connect to with my laptop with no problems - DHCP address is given correctly and I can access the internet.

  I tried to manually assign an IP address to my office (192.168.1.5) and I am able to ping the router, but I can't http or telnet to the router's GUI or get on the internet.

  I guess the problem is with the office and certain components of the software, but I don't know what. Sorry for this long post, but anyone with ideas.

  Thank you

• Need to connect MacPro to the router

  My Mac Pro is now connected to the internet via the airport card and the modem is down. But I need to connect a router on a mac so I can run my laserprinter through a network using a RJ45 cable. I can't run the cable in the area of the modem is located. Can I connect the router directly to Mac and use the card airport as the internet connection?

  Dbarunas,

  You left out some important details, but let me see if I can answer without them:

  Assuming that the ISP modem you mentioned is your current destination of wifi and Airport card is built-in wifi Mac Pro adapter.  I also guess your desktop not a laptop since you don't mention MacBookPro.

  1. If your router is wireless and assuming that the 'airport' is the the computer's built-in wifi card.

  (Wired connection) modem-> router (cable) * (wifi)-> laptop (wifi) (* printer cable) to connect to the router via wifi instead of the modem, then turning off the wifi on the once the router WiFi modem set up, if possible. (No need to nuke the family bits with too many signs wifi).

  2. If your router is not wireless.

  Modem-> laptop (wifi) * (wired)-> router (wired) (wired)-> printer (cable) (* make sure that the computer has not a gateway specified in the network settings for this connection assigned static address.)

  3. If your router is not wireless and no other host on the router. (without router required)

  Modem (wifi)-> laptop (wifi) (wired)-> * printer (cable) (static addresses the only, once again no gateway) (* this may require a crossover based on the capabilities of the printer Ethernet cable.)

  When you use a wired network on the laptop and wireless Internet access, make sure the "backend" network cable is on a completely different range of addresses and 'NO' gateway assigned or the laptop would not know how to get to the INET.

• 9.3.4 disabled wifi on an Ipad, but it connects to the router. Just don't download at all

  IPad was working fine, but I've updated to 9.3.4. Now Wireless does not work. Shows connected to the router, but nothing happens, but say unable to connect to the server, error trying to access the internet or by mail. Also turn continuous flashing VPN gray to green, then again, but we have never set up a virtual private network. Don't know if it is connected. Have you tried

  1 disconnection / reconnection to 2 routers that work very well for other devices

  2 reset wireless via settings > general > reset > reset network settings and then hang up again

  3 airplane mode on, wait a few minutes, then shut off again

  Overall, the router will connect to any time, we put the password, but there is no transfer of data. 3 other devices work fine with the router. Don't know where to go from here, or if it is possible to back out from the upgrade. Anyone else having this problem? A research increase the same problem.

  Thank you

  Anything that causes the problem is not specifically 9.3.4, which fixes just a security breach. Have you tried to restart routers?
