Loss of wireless connection, Laptop

by splittingeve / January 24, 2013 7:23 PM PST

System in question;
Aspire One D255E
Win7 starter, Intel 1.66, 1 GB RAM, 250 GB HDD
Atheros AR8152/8158 PCI-E (NDIS 6.20)
Broadcom 802.11n

Hey all - connectivity issue here. My sis has the above laptop. For a year or better, she has been wirelessly connected to her local network, via a Linksys E2000 router without issue.

Rather suddenly a couple of weeks back, she found she had no connection. There were no changes to this network that I'm aware of (the users don't even know how to change settings online for said network). Several available networks show up on the list (hers and a couple of unsecured neighbors I believe). Despite full bars for her local network, clicking 'connect' has no visible effect. Nothing happens. Not like a 'failed to connect' or something similar, just...nothing.

I went through various steps such as;
1) power down, wait and reboot the modem, router, and her laptop, in that order
2) 'hard' reset router at power up to restore defaults
3) uninstalled network adapter(s) and reinstalled - with the company site's latest drivers - they installed, and 'ready to use' appeared
4) ran the various (fairly useless) Winodws network diagnostics which essentially told me I hadn't selected a network...which I had...repeatedly
5) Swapped out router completely with another, with the same results
6) Took laptop here, to a completely different network, again with the same results
7) assured that fn+F2 was not the issue, wireless is enabled

The local networks I'm attempting to connect to are unsecured - no password, etc

So, any idea what I should try next? My experience here is rather limited, and I've run out of ideas. Thanks much for any suggestions!

I have found that

When the antivirus software has expired, it will give similar symptoms without any real warning. Check that first. Next, malware/spyware can mess with internet protocols, so do a thorough check with the antivirus software. If all that comes back good, then come back for the next installment.

She uses a free antivirus (AVG) without expiration. That said though, I'm running some scans now to see if it's dirty. Thx

No hook up

Does it work on a hardwire hook up? Have you tried doing a rollback to an earlier time? As a prior poster mentioned, possibly a malware issue. First things first, try hooking hardwire to router...then do a roll back..then pursue malware issue.

wired works

She did a sys restore just before I arrived, though the results were something along the lines of 'cant restore' she tells me. Not sure?
It does work when wired, just tried that out - no problems there. Running some malware scans currently, and will post findings. Thanks.

If you are using Malwarebytes and doing a scan for issues, boot to Safe Mode With Networking otherwise you might be spinning your wheels.
