• 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?

• I don't have an icon of Ad hoc network when I try to add the connection

  So I will try to set up an ad - hoc network so that I can update my other computer (no internet and I'm not lugging this thing down a flight of stairs). But I don't have any Ad-hoc icon when I go to the "establishment of connection or a network.

  Control Panel > network and sharing > set up a connection or network

  After the dialog box appears where he is SUPPOSED to have the option of ad-hoc connection but does not work.

  I use an Acer Aspire 5920 (it has wireless networking capabilities. My friend put up the ad - hoc on his laptop computer {exactly the same model} perfectly well. Which means mine is just well... _)

  How can I solve this problem?

  Hello

  The host computer needs two network cards (below). The host computer must be connected to the router via a card (wire or wireless), the second card must be wireless to connect to the wireless client computer.

  Instead of the Ad - doc, you try one of those too.

• 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.

• HP Envy 4500: Printer connected to the router, but will not print wireless Macbook

  I want my wireless printer to work on my macbook, but I can't. I tried setting up on the HP utility to connect with the router as the mac and printer on but it does not work! It indicates that the download was successful, but the device was not reachable. I don't really know where to go from here and any help would be really appreciated. Thank you.

  Hey @miriamnimmo,

  Welcome to the Forums of HP, I would be happy to help you! I understand that you have the printer set up on your network, but the software says that the device is not accessible. Sometimes the IPv6 may interfere with the connection, and I suggest we disable that before anything else. On the fornt of the printer Panel, scroll down to and then select Wireless. In the wireless Menu, select Advanced settings, then IPv6 and.

  Now we are going to let the router and unplug the power cable (NOTE: do not reset the router), then do the same with the printer and shut down the computer. After a minute, plug in the router, wait to fully turn on, then plug the printer back in and wait for the wireless light become solid. Once the router and the printer are on, go ahead and re - turn on the computer. This will refresh the network connection.

  Please let me know if this solves the problem by marking your post as solved (click on Accept as Solution button below). If the problem persists, let me know, I'll watch for your reply.

  See you soon!

• Unable to connect to the router

  -Please ignore this message: I did not wait enough to do the factory reset. It seems that launch a factory reset without waiting for 10 seconds only restarts the router.

  Hello

  Today I tried to connect to my router (I do not use it for a few years) and it didn't work at all.

  Initially, I plugged it in just 2 RJ45 cables: one for internet, one for the PC. The computer could not connect to the router (DHCP failed).

  I then restored the factory settings and tried again: same thing, the computer could not find the router via DHCP.

  I tried to force an IP address (IP: 192.168.1.5, mask: 255.255.255.0 Gateway: 192.168.1.1).

  By forcing the INVESTIGATION period, I was able to connect to the router, but when I tried connect to 192.168.1.1 with admin/password, it wouldn't let me (bad password - don't forget I restored it to factory settings, several times actually). The address http://routeurlogin.net/ is not found (404) and I was unable to go on websites (404). A curious thing is, using this connection, I was able to connect to Skype (and send/receive messages), although the sites Web could not be reached from a browser.

  I'm running out of ideas to solve the problem, but I suspect a hardware problem, so any help would be welcome.

  Yes he did.

  I couldn't find an option to delete my message, otherwise I would have done it.

• Cisco Connect connects to the router E2000

  I got an E2000 router, set up and works very well for years. Today, I tried to connect with Cisco Connect, I want to establish a network of separate comments (by the way, if there's a way to do this through the web management interface, please let me know!). However, the software is unable to connect to the router; the progress bar gets to 25%, and then eventually times out. I tried several computers on network, cable and wireless, with the same results. Any suggestions? Thank you!

  I solved the problem; I activated the setting "Allow users to set up" in the "Administration" tab, as well as utility access Web via HTTP. I don't know which of these settings did the trick, but I was able to connect and configure the network invited (even from a PC wireless).

• BEFSRU31 - connected to the router, but can not browse the internet.

  Hi, I had this problem in the last three months. I share a Linksys BEFSRU31 with my friend. However, once or twice a week, or even more frequently, the router suddenly ceases to send data to my computer. However, my roommate still receives data. So I'm unable to browse the internet even though I am connected to the router and the router gives me an IP address. The only solution I found to do this is to reset the router, which is annoying, because the router is in my friend's room and I don't like to disturb whenever this happens. The ISP is Optimum Online, and I'm on a cable connection 8 MBit. Can someone help me please this problem? Thank you for your time and your collaboration.

• Help! Setup Wizard cannot connect to the router!

  I tried several times to install this router wireless MO # BEFW11S4.

  I get an error message that Setup Wizard cannot connect to the router!

  I pressed the reset on the back button each time, it is turned off, check the cable connections between the modem cable to the router, then router to the computer.

  After dropping out of the router and connect the PC to the top with the modem, the PC is then connected to the internet once more.

  How to solve problems, or isolate the problem as a bad router?

  Please send me a PM for any suggestions or help.

• Printers HP B110a cannot communicate with the laptop, but both will be connected to the router?

  OK, here's an interesting problem that has been banging my brain for hours, one of my friends has a HP Photosmart all in one printer B110a. Now I can get the printer to connect to the wireless router, no problem. Can I also have the phone to connect to the router, the problem is that the printer cannot communicate with the laptop. The router brand and model is the Linksys wrt54g

  Now, I took my friends laptop home and tried to see if she could detect my wireless printer model different on my router which is a TP WR340GD I went in devices and printers, and went to Add a printer and Add Printer wireless, it instantly detected my printer via the wireless network. There is no problem on the side of the laptop. I am sure that any firewall on the laptop was turned off when I tried the connected printer.

  So now I have my friends printer here with me and decided to try and see if I could detect the HP Photosmart printer All In One Printer on my laptop on my TP WR340GDwireless router. Yet once, it worked perfectly and it has detected the printer and works wireless without fault.

  I'm down now to the conclusion that the problem is with my friends router Linksys wrt54g I'm gone in the settings of the router, change the wireless channels, changed security between WEP and WPA/WPA2 and AES AND TKIP wireless and this does not solve the problem.

  I can access to the Photosmart B110a: the Web server integrated in a browser ONLY if I have the laptop to the router physically connected by Ethernet cable when trying to access my router from a friend, but I can access through wireless on my router. The problem is probably something very simple that I forgot, but I was more all I can think that I tried to reset harder than the printer cleaned the network settings on the printer as well from the display of the printer menu.

  I'm really lost now, someone at - it suggestions?

  Hey pcwizard, ok, I checked the router settings and Mac filtering turned on, so I decided to reset the router, it restored to factory settings. Re-Setup wireless and once again I tried, still had no luck with the laptop to communicate with the printer.

  in any case, I decided to connect the cable from the printer to the laptop and took the USB to wireless Assistant. As I reinstalled it the printer using the wired method.

  He told me that the rules of traffic incoming and outgoing firewall stopped communication between devices and assign port numbers 427-9000 etc.. However, I had turned off all firewall, Windows and Norton 360, which since then, I've replaced with a better anti-virus software.

  I went into the settings of the router, port forwarded the application numbers, tried again and is again no luck. I'm usually pretty good with computers, but it was really annoying me. So I went and had a coffee and a brainwave came and I decided to see if my laptop could detect and connect the printer to the router. As soon as I tried it, he finds and the printer has detected immediately.

  Then I thought there must be something on my laptop to friends who may be at the origin of the problem, when I looked, I noticed that my friend had the old software Vodafone Mobile Broadband running in the background which was connected to the router.

  So I closed and turn it off and tried again adding printer. SUCCESS now detects it and the printer is now communicate and respond with the laptop. I'm guessing that the Vodafone Mobile Broadband have a built-in firewall blocking the communication. However it is strange because it worked without problem on my printer at home, so I wonder if some how blacklisted broadband Vodafone IP address of the printer at a time on their router.

  I'm so happy, it's finally done, a lot of hours and work, and after all this time it was * beep * Vodafone.

  in any case Pcwizard I thank very much for trying to help, no doubt has given me a few ideas.

  Thanks again!
