Local only but able to connect with unsecured network

[hiphouse]

my friend has a HP laptop with window vista sp1. he can't connect to the internet if it's secured with or without wire connection. however, he can connect to the network if it's unsecured.

the router is Cisco E2000 and my other roommate (acer, windows 7) and i (mac) can connect to the network without a problem. all of his network adapters are updated, and we've tried everything as far as google can tell me but nothing works.

please help! Thanks!

The ethernet problem may be a defective cable or NIC or a mis-configured, corrupted or out-of-date non-Windows firewall or security suite.

The following was put together mostly by etaf with a little help from me.

------------------------------------------------------------------------
Atheros AR5007EG & AR5007
We have been seeing a lot of problems with the above adapters for about a year, mainly concerning WPA and WPA2 encryption and windows Vista.

The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
--- Please post back here if that works or does not work.

Here are a number of possible solutions

--- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

--- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.
Toshiba - update has worked for some PCs
HP The latest HP Atheros driver dated Sept 2010 has fixed the issue - so check the driver date, However, that does NOT apply to all HPs / Compaqs machines
- the poster did an online scan for driver updates on the HP website here HP Product Detection which resulted in a solution. Solved: Can't connect to internet wirelessly - Atheros AR5007 Wifi through Clear Comm - Tech Support Guy Forums

If you can post the Make and EXACT model of your PC here, along with the windows version you have and we will see if we can find the driver and will post a link as a reply here.

--- 3) On one occasion re-setting the router back to factory default and re-configuring the router settings has resolved the issue

--- 4) A few posters here with the same issue have found that the driver from this site ATHEROS drivers for Microsoft Windows resolved the issue

I do NOT know anything about the site mentioned ATHEROS drivers for Microsoft Windows

However, if you do decide to try the driver, Please let us know the outcome

Direct link to the drivers are below
You only need to click on the green download button labelled " click to download " and wait, the file will download - you do not need to click on any other buttons to get the download started

Although this driver has shown up in BSODs (Blue Screen Of Death) on Vista SP2 systems, usually conflicting with updated Vista OS drivers like netio.sys, tcpip.sys and other networking related drivers.

Assuming that after all the above the wireless still does not connect to the internet, all I can suggest is to use wireless security of WEP or to get an external USB wireless card.

You might also bug your laptop's tech support about the problem--maybe people can put pressure on Atheros to find a fix.

thank you for your help, but none of those options work...

any other options? we even deleted his security thing. (it was called AVG.. i think) and it still doesn't work.. tried tinkering with firewall, but nothing...

funny part is that it connects when the network is not secured.. should i change settings on the router?

Last two paragraphs of above post:

The last sentence probably needs modifying. Some OEMs do have working drivers now, so maybe Atheros has made their fix and it's just the other OEMs that need to get their act in gear.
