Atheros AR9285 constantly disconnecting/reconnecting

Hi there,

I have an HP DV7 4010-TX bought from Australia roughly 4 years ago, I am now residing in the UK. For the past few days I have been having problems with my wireless card (Atheros AR9285) constantly disconnecting and reconnecting to my network as well as timing out whilst loading websites etc. This seems to be getting progressively worse; started off every half hour and now every two minutes. I have also noticed that the signal strnegth is now only good compared to excellent before.

So far I have uninstalled and reinstalled my card using the latest drivers as well as some previous ones, reset my internet protocol setting using command prompt and tried to use the windows troubleshooter which finds no problem as the network connects again before it detects that there is no internet connection. All other devices in the house using wireless work fine, xbox 360, other laptops and mobile phones. The computer has been on the same desk for two years with the router in the same place with no real problems.

Is there anything further that I can try or does it look as if my wireless card is dying? If so can anyone recommend a suitable replacement for me. If there's anything I have missed out please let me know, little new to this kind of stuff.

Thanks for any help and suggestions!

Cheers,

Millsy

Have you tried starting up in safe mode with networking? If the problem seems to go away in safe mode then you can be sure than an installed program or software is causing the problem.

Hi,

Have just tried safe mode with networking, exactly same problem.

Where do I go from here? I am happy to buy a replacement wireless card if that is the most likely cause. I am not sure what card to order though as from what I have read the bios on my computer will only work with certain cards? Not sure if this is correct but I would like to upgrade the card instead of a like for like replacement if possible and don't want to order something that isn't compatible. Is there an easy way of determining this?

Is there anything else to try before giving up and ordering a new card?

Thanks for your help.

Yes try running the following command in an elevated command prompt, this is just to check if the system files are not corrupted which is a common problem.

Code:

sfc /scannow

Thanks for your replies.

Chev:

Did sytem scan, appears no problems -



Boohbah: I have tried about 4 different driver versions, currently using a set that fixed the same problem for several people, I'm unable to find the forum thread again though. They seemed to solve it for me for a day or so but the problem has now returned. Tried disabling/enabling, same results as before. I'll give the ones from that site a go.

I don't know if the following screen using Xirrus wifi inspector provides any information. Had it on my computer so felt may as well put it on here.



Anything else I can try?

Thanks to both of you for your help.

Well it's not a system file problem however, the signal strength I'm seeing here is very unlikely to create a reliable connection. You might try using a different channel for the wireless like 11 or 6 but with this low signal strength you should expect a non reliable connection.

The signal strength always used to be stronger, it would say excellent whereas now it says fair. There are about four other networks nearby that used to show up as well but my computer can no longer find them. Is this an indication that my card is slowly dying? Neither my laptop or router have moved. Maybe best thing is to just buy a replacement card, they seem fairly cheap from what I have seen.

OK. If I change the channel do I have to change this on devices in the house or will they just connect as normal?

Last question, sorry! If the card dies before I have a replacement will I still be able to use a wired connection with my laptop in the meantime? I do half of my work from home and use the internet heavily for this.

Thanks for all your help.

The channel is changed on the routers WiFi settings. You may also see better performance when using the 802.11N Only setting versus the Mixed WiFi settings.

Yes the cards aren't very expensive but I'm not sure why it would suddenly lose signal strength. Resetting the router may help in this case. The wired connection should still be fine, completely different connection for that.

I'm not sure what the Easy Tether network is but if it's used to create a secondary access point then it may be causing problems with your wireless connection.
