We recently moved to the 350mbps package and while the speed stays normally above 300mbps, games have been unplayable with the lag I get most days. Not really sure what I can do.

It's a terrible BQM:

Could you access your router using http://192.168.0.1/ or http://192.168.100.1 for modem mode. Log in, select the 'Advanced settings / Tools / Network status' option and paste your 'Downstream', 'Upstream', and 'Network Log' tabs? Please copy/paste this data as text, split between multiple posts (Sometimes you have to click 'Post' twice due to an error message).

There's a lot of timeouts in the log, but power and noise levels look OK: BQM looks as though there may be over-utilisation, but I can't see why that would occur because of a speed increase.  User @jem101 knows more about these things than I do and may be able to comment.

Was the lag there before you upgraded, and if so, how long has it been going on, and what motivated you to upgrade?

[dilky2002]

Before the upgrade just before Christmas i would only really get drops in speed, not latency spikes. We got the upgrade because we were offered sports channels for good value.

From what i remember though i didn't lag when we first upgraded, only really since the new year
