I seem to have a problem with my wireless connectivity where anywhere not within 10m of the router the connection cuts in and out with the yellow 'limited connectivity' sign is always appearing. disconnecting and reconnecting fixes the issue for a few mins. Ive resorted to sitting very close to the router.
the computer is 2 months old, the Wlan driver is up to date. the power options have been configured to be on maximum performance for Wlan etc etc.
The main thing that gets me is that all the other (a lot older laptops) in our house work fine where mine doesn't. I have actually lost performance in terms of where I can get wireless signal from my old toshiba portege m300 to this new one.
In terms of information, computer is running windows 7. Wlan card is Atheros AR9002WB-1NG.
If theres any other info you need, as im sure there will be, let me know and Ill try my best.
Please be sure that you use the latest driver v18.104.22.1689.0
To be honest, I had the same idea to disable the power saving for Wlan and it most cases this should functions… are you sure you have changed this in the same power plant which is used when the notebook is running in battery mode?
However, it would be also interesting to know if the L750 Satellite uses the same 802.11 Wlan standard as other notebooks do…
In device manager -> Wlan card properties -> Advanced tab …you can choose the 802.11 Wlan standard…
Would recommend checking this…
