Hi all, 

Ive been using my M5 Mesh system flawlessly for past 9 months or so with Virgin, getting tyhe full 350mb download speed at each node. I changed to a new supplier, Grain, 3 days ago and all Im getting now is 70 to 100mb download speed. My main node thats wired into the grain modem gets 500mb but thats where it ends. We run 2 PC's with each getting 70 to 100mb now where as we used to get a stable 350mb. Ive been on to Grains support but they dont seem to want to help, just get told to move the nodes when they have been working perfectly for past 9 months in the position they are in. Are there any settings I can change as the Grain support said they may be issues with DHCP or SSID? Ive tried changing to 5ghz only and running in access point mode but no improvement. Anyone got any advice please?

Many Thanks

David
