Laptop loses connection to internet via wireless router


[link to this post]
 
Hi, not sure where I should be asking for help on this ...

My laptop frequently (at least every 2 hours) loses it's internet access when connected to the router by wireless. The only way to get it back is to disable the wireless adapter & re-enable (or restart, which does the same thing).

Note, it does NOT lose connection to the router, the signal is still strong even when there is no internet access.

My android phone, however, does NOT lose connection to the internet at the same time ... so it is not the ADSL router itself.

My setup.
ISP: Talk Talk
Router: Huawei HG533

Laptop: Sony VAIO Fit-15
OS: MS Windows 8.1 64 bit
Wireless adapter: Intel Wireless-N 7260

Symptoms:
... The wireless will suddenly show "no -internet access" & there will be no connectivity to the internet. ... the HG533 is still visible on the network.

Note: 1. This same laptop is rock steady at client sites (I'm a developer & have used this laptop at 3 separate client sites in the past year. The only time it lost connectivity was when the entire client site went down ...
Note 2: The only other device I have is my android phone, at at the same time the laptop loses it's connectivity, the android phone is fine.
Note 3: If I connect to the router via Cat-5, then the connection is rock-steady (and if I lose wireless and then plug in the cable WITHOUT doing anything else, I immediately regain internet access ...

Things I have tried (that make no difference):
1. disconnect / reconnect wireless connection
2. "forget" wireless connection & then reconnect
3. restart the router

The ONLY thing that works is disabling / reenabling the wireless adaptor.

Any ideas?

Try running "netsh winsock reset". You will need to reboot.

It looks like this is a long-standing problem with the Intel drivers. Check out the penultimate post at the end of this thread. However, since the date of posting is Feb 17, the issue may still not be resolved.

Reading through the thread, other suggestions are to turn off Bluetooth (if you're not using it), turn off HT (greenfield) mode, or restrict channel bandwidth to 20MHz. Unless you live in the middle of a field, running dual-band at 40MHz is a bad idea and pretty anti-social. Using a wi-fi scanning utility will show you if you have any channel clashes.

If you still get no joy, try plugging in a wireless dongle. Of course, if the lappy is still in warranty, you could chuck it back at the shop.

Oops! Just noticed a typo. I did have "Unless you love in the middle of a field..." crazy
