My wifi adapter crashes my wifi connection

[Anonymous]

In the last few days this has been happening: if I connect my laptop to the wifi, the internet becomes unstable (for all devices) and sometimes it crashes. If I perform a speed test, it shows very low speed most of the times. This doesn't happen with my smartphone, which works fine, unless my laptop is killing the connection.

Luckily, a couple of years ago a bought a usb wireless adapter and if I use that to connect to the same wifi the issue disappears. At the same time, however, my laptop doesn't have any problems connecting to different wifi networks.

I have already tried changing/uploading the wifi adapter (Ralink RT5390R), but for some reason it doesn't let me change it, it always goes back to that one.

So now I don't know if the culprit is my laptop or my modem (which is called "Vodafone Station Revolution", not very customisable)... or both!

Please help, I've run out of ideas.

Thank you,

Tommaso

I reviewed your post and I understand that you are having issues with the wireless connection.

I’d love to help!

In order that I may provide you with an accurate solution, I will need a few more details.

• When was the last time the computer was working fine?
• Have you made any software or hardware changes on the computer?

Meanwhile, follow below steps and check if it helps.

Reset the TCP/IP settings on your PC:

1. Go to your start screen/menu and type CMD.

2. Right click on the command prompt icon and chose Run as administrator.

3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.

4. Restart your PC and test.

It may also help to reset the winsock catalogue:

1. Go to your start screen/menu and type CMD.

2. Right click on the command prompt icon and chose Run as administrator.

Hi, thank you for helping.

The last time the laptop was working fine was last Wednesday, I suppose, and I don't remember installing anything or changing any configurations, but I might remember wrong.

Unfortunately your suggestions didn't work.

However, I think I finally understood what's wrong, but I don't know how to solve the issue. Basically, if I change the modem settings to "wireless 802.11b/g", it works using the "g" channel, meaning it doesn't crash the connection. If I reactivate the "n" channel it crashes again. So I suppose that is the issue, but I wonder why it has happened all of a sudden when it has always worked just fine. Could it be that the wireless adapter is "partially" broken?

Cheers.

Hi

Your description of the fault/cure is not clear.

Your ISP modem/router has 2.4 and 5.0 Ghz frequencies, and your problems are on the 5.0 Ghz channel?

If you used an old, free version, of inSSIDer and looked at what channels were being used by neighbours etc and your own local devices you may find a clear channel to operate on.  Like in the piccy below...

You can see the congestion on Channel 11, and using Channel 1 was my next move.

802.11g devices suffer interference from other products operating in the 2.4 GHz band, for example wireless keyboards.

You have found a solution, and I hope you can improve on that in the near future.

Hi!

I checked and I am connecting with the 2.4 Ghz channel, both when I use "802.11 n" and "g". However, if now I use the n standard (which I think is the fastest and also the one that I have always used), the laptop loses connection constantly, while with the g standard it seems to work (even though not at my connection's full potential, I presume).

I have tried changing channel, but it doesn't solve the issue.

I think the problem is either in the wireless adapter or in my modem. Anyway, as you said, I can navigate using the "g" standard in the meantime.

If anyone thinks they have a possible definitive solution, I'd be happy to hear!

Tom

NB. When I say "laptop loses connection", I mean that internet is not available anymore and that the router often reconnects. I do NOT lose wifi connection.
