Hello, new to Mudcat - hi :)

I have the same issue. We use wifi here generally however have recently installed Homeplugs to get internet access where wifi reception is poor. Wifi works okay as long as homeplugs aren't communicating. If you try to use the wifi with the homeplugs disconnected, I reckon you'll find the wifi connection is fine. The homeplugs are known for causing interference with wifi signals, this is a pain.

Good luck :)
