Hi,
I have been on Talktalk fibre for some years now using the TalkTalk Huawei HG533 router with the open reach white modem and was getting a stable 37-38mbps download speed. However a few weeks ago I upgraded to the super router due to the new contract but my speed has slowed down and become erratic, anything from 25-36 depending on the time or even back to back tests. I have rebooted the router and also reset it but it hasn't fixed it. I know I can get a least 37mbps download as I have had it for the last 2 years or more.
My wifi signal is strong so I don't need to change the channel as far as I can see. I'm not sure what else I can try to improve it? I have also noticed that the new router creates a shhh noise on the phone which the other setup didn't but this is a minor issue and could be normal I'm not sure? Please can you help?
