Entire network slowed down

[omgitslurch]

Hi,

I noticed tonight that my entire network suddenly went to a crawl, over Wifi, Ethernet, and accessing the Internet. When checking the logs on the router I noticed a load of entries that I'd not seen previously in the logs.

Router is running 1.06h and has an uptime of 43 Day(s) 20 Hour(s)

Ended up restarting the router in order to get everything back to normal. Though once it had started back up the router had lost all its settings and was back to the factory defaults.

This seems to be a common fault, mine has started doing exactly the same and I've noticed other's post the same.

Not sure if this will work but you could give it a try as it could be an autotuning problem which can cause network slowdowns.
