Wireless usb drops after 100secs

akb87 · 06 Apr 2011

Hi everyone, so I did a clean install of windows 7 64 bit sp1 yesterday. It was an upgrade from windows 7 64 bit. The wireless usb worked fine before the upgrade. Now it won't stay connected for more than 100secs.

I have a TP-Link WN722N; d-link dir-655 router. I installed all the new drivers, disabled IPV6, don't have any firewall, anti virus, etc, but still it disconnects after 1min45sec. And I have to either unplug and plug it back it or use the trouble shoot option. And the trouble shoot would say "problem with wireless adapter or access point".

and I tried to go back to windows 7 64bit but the problem persisted, so I am stuck.

Please help, how do I fix this? this is so annoying.

akb87 - Welcome to SF,

Please try these recommendations:

Have you tried a wired connection? Were you able to replicate the issue?

Make sure that 'Obtain DNS server address automatically' is selected from your Wireless connection. Here's How.

Remove your network encryption from the router, test your connection after. If you can't connect, try a WEP security.

Disable the problematic Wireless Network Adapter's power saving mode from Device Manager, locate the Network Adapter=> Wi-Fi Adapter=. Properties=> Power Management Tab, in here you may disable any Power Save mode options by unchecking them off.

Test your connections after, and if it's still an issue please provide the following:
======================
Click on Start => in run or search box type cmd, press enter. Open up a command prompt, run as an Admin then Copy and Paste these ipconfig /all >c:\ipconfig.txt . Please attach the .txt file to be found in your Local Disk 'C' on your next post.

From your wireless computer pls. install and run Xirrus Wi-Fi Inspector.
Click on the 'Show Networks' to display all wireless networks on the xirrus icon on your desktop of if you have one running in a corner. Tap the Printscreen key on your keyboard, open up Paint then choose Edit from the Menu and select Paste, then SAVE it. Upload and attached it here, click on Go Advanced and locate Manage Attachments Tab and attached the file.

Please post back and give us an update.

Make sure this isn't checked.

Hi all,

Thanks for helping.

1.Wired connection: worked fine. tested it for an hour, no drops.
2.'Obtain DNS server address automatically' is selected
3.disabled Power Save mode, no luck
4.disabled security option from router, still dropped after 90secs.
5.reset router, still drops.
6.try using wep, no luck

I really don't get what's going on. Should I go get another wireless usb to test it out? I have only been using this one for 3 months.

Thanks for the Xirrus snap shot. No one is using Channel 1, pls. change the Wireless Channel to 1 and see if it helps.

If changing the channel didn't help at all, and if your router has removable antenna, you may replace them with High Gain Antenna, get at least 9dBi or higher. You may also replace your Wi-Fi Adapter with High-Gain Antenna.

Thanks for the quick response 2xg! I changed the channel, no luck.

I don't think it's the reception. The router is right above my room, and I used the wireless usb on my laptop (running ubuntu) and it worked fine, no drops at all. I think it's the setting in windows or d-link. At this point, I am leaning toward windows, because Id never had a problem with wireless before the upgrade.

According from your Xirrus snap shot, your neighbors do have excellent Signal, yours is just okay.

If you can borrow somebody else's USB Wi-Fi Adapter and install it in your computer, see if you can duplicate the issue.

Just to update on the situation.
So it turns out it's not windows, it's not the router, it's not the wireless usb. It's the motherboard. For some strange reason, changing the settings for usb in the bios made it work.

Internet has been going strong for 2 days without dropping now. Will report back in a week to give a final update.

Thank you 2xg for all the help!

akb87 - Glad to hear that your internet has not been disconnected for 2 days now. I hope that it continues and thanks for posting back with an update.
