Solved Two wireless adapters, same location, large disparity

July 20, 2012 at 11:53:44
Specs: Windows 7
My home wireless network is supplied by a 2wire 3801HGV on AT&T U-verse.

About 30 feet away, around a corner and through a wall, I have two wireless adapters connected.

First, I have a Lenovo laptop W520. Second, for my desktop, I have a USB adapter - Medialink MWN-USB150N.

When I move the desktop USB adapter right next to the laptop, both will vary greatly in performance.

If I drop to a mid or low wireless channel, the laptop sees huge ping times and packet loss. On these channels, the USB wireless adapter works fine.

If I switch to a high wireless channel, the results switch, so the laptop is fine but the wireless adapter (for the PC) now suffers greatly.

What can be done to resolve this issue? I would be fine with buying a new wireless adapter for my dekstop, but I don't know how to differentiate based on my issue, nor if that would solve the problem. Thanks!

This sounds to me like the radio in your router may be having issues to be honest. How old is your router? If it's more than say, 3 years old, you might want to consider replacing it if you can afford a new one. Or alternatively, buying an Access Point and plugging it into the router.

I would start by ensuring both interfaces have the most recent drivers possible. If one or both does have newer drivers, install them and retest and see if the results differ.

You would download xirrus wifi inspector and run it. You would set your channel to not be the same of those close to you.

Only channels 1,6 and 11 are nonoverlaping. These are the preferred choices

Thanks for the responses. I installed the latest drivers for the desktop USB adapter. I installed xirrus wifi inspector and inSSIDer to watch for anything (not sure what) as I flipped through the channels.

This time the results were different. For a couple hours, no matter which channel I selected, the laptop had poor performance and the desktop with USB adapter had .. non-functional performance. Loading the modem's web interface took several minutes, even after a few retries.

The installed software detected over a dozen networks nearby - most on channels 3 and 11. I settled on channel 6 (least competition).

At some point, my packet loss issues on both setups diminished. I am back to decent speed on both. I don't know why.

This doesn't confirm my earlier observations but I wonder now if I have interference from any non-network devices. I'm not sure how to identify such interference with the installed software. I've seen no change in nearby network average strengths since I had the problem earlier, and now with no problem.

Would there possibly be an issue other than interference?

Interesting. The modem / router combo unit itself has wireless access, and while it's not old, it's in fact brand new.

Last month, I phoned AT&T in to report a different kind of issue - the older unit (modem / router combo) was intermittently resetting itself. They replaced it with this new unit. I assumed the previous problem was just masking the current issue.

Either way, you're right in that I need to get some other equipment and change the network setup to further investigate (or out right solve) the issue. I also need to spend more time figuring out what causes my originally posted issue, and what causes the current issue.

Thanks again.
