. . . with a untuned radio the plug next to the master socket buzzes like hell, the socket is switched off but still buzzing . . .
Hi Woppy and welcome,Are the SNR drops causing your modem to drop and re-sync ?If not, I wouldn't bother as actual ambient noise varies naturally, thus affecting the signal to noise ratio.Kind regards,Walter
HiYou really need to have more info to be sure you have a REIN problem. Try routerstats . This is a usefull troubleshooting tool. You can plot The snr Margin anf synch rates over any time frame required , and as its plotted as a graph will help to Identify REIN(normally very spiky ) or otherwise .Regards Jeff
