We have a Vigor 2760n providing wired and wireless network, and internet access. Generally all works well, but every two or three days we loose the wireless network. Each time I need to log into the router, go to >>Wireless Lan >> General Setup, and click the option 'Enable Wireless LAN'. It will the run for a couple of days before failing again. Machines on the wired network remain unaffected.

Can anyone suggest why the router might be dropping the wireless LAN periodicity, or even better suggest how we can achieve a stable wireless network?

Router is Vigor 2760n originally with 3.7.5,x firmware, now upgraded to 3.7.8.2
Firmware was applied to try and resolve this issue, but has made no difference, Wireless LAN fails for both firmwares.

Something nearby upsetting it? Try changing channel...
