Problems with Wireless on Win 7

Hi all. My employer has recently replaced my ageing Dell laptop with a new HP ProBook 6460b with Windows 7 Enterprise. All good so far, nice machine etc. Over the last couple of weeks, the network side of things seems to have been behaving oddly, so before invoking the nightmare that is off-shore internal support, I thought it worth mentioning on these fine forums.

The symptom is, at times when switching on at home, instead of showing the usual Windows 7 wireless icon in the bottom right corner, I get the LAN icon, with a red cross on it. It's like Windows is ignoring anything wireless, and showing the fact that I have no LAN connected. If I plug a LAN cable in, it picks up and works, and after a couple of re-boots the wireless will then usually be recognised and it connects OK.

I had this last night, and a couple of re-boots didn't fix it, so I did the following:

netsh int ip reset reset.log
netsh winsock reset catalog

...and rebooted, after this all was OK. The wireless is an Intel Centrino Advanced-N 6205, connecting at 5GHz to an Asus RT-N56U router on 40Mb FTTC.

Our other laptop also connects on the 5GHz network without issues at this time, and the phones / DS's are all OK on the 2.4GHz network.

Any clues anyone? I loaded the latest drivers for the WiFi adaptor from HP's website a few days ago, as Windows was reporting that the drivers I had installed were corrupt. All has been fine since then until last night. I do 24-hour IT support and don't need any extra complications at 4 in the morning!!

Thanks...

so,

you had an issue

you found a fault

you fixed the fault

the problem went away

do oyu really need more input?
 
Sorry, I probably didn't make it clear - I've done the 'netsh' stuff before, and if I have to keep doing that to fix things then there is obviously something wrong. I was kind of hoping others may have seen this behaviour and actually fixed it properly.

that re-jiggs your network-a-ma-jig gubbins, I would point hte finger at a virus or firewall..

when you look at the dialogue that shows you the card bindings - IP4 / IP6 is there anything odd looking there it may be the remains of a firewall filter...

I assume you are actually turning the machine off and not allowing it to sleep / hybinate?
 
Yep, I do turn off. I've checked the IPV6 and IPV4 and there is nothing odd going on. I wonder if Windows is hanging on to a profile of some kind, as some days I'm docked in the office, and others working from home on wifi?
 
Only time I've seen something like that was when I had used the vendors software/driver for the wireless card rather than letting windows autodetect and use it's own.

Good few years ago though and on XP, so possibly completely unrelated.

What happens in device manager when the LAN computer appears and wireless dissappears? Use search to check my posts, I had the same issue with this card in an EliteBook 8460p.

Turned out it was a bad batch so might be worth trying another Centrino card (same model otherwise the BIOS black list will block the card).
