WiFi Keeps Dropping

[#1]

For the last couple of weeks, WiFi keeps dropping and it's really annoying.  No settings have been changed on the computer or router so don't know why this is.  Internet (wired) seems OK.

If a dual band router ensure you give the 5ghZ band a different SSID name.
D/load a free wifi analyser app, and check wht frequencies most in use in your locale.
Then choose the least/ not used wifi channels, by adjusting router.
5ghZ is currently less populated, has more channels, but has less range from router.

Many thanks Gel, I've done that and so far so good - will keep an eye on things over the next few days.
