Hi, hope someone can help?

Over the past few weeks my normally rock solid M350 upload connection has gone from 36meg to just 4meg (or less) upload.

Any ideas? Thanks Pete

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).

Create a BQM and post the live link.

Thanks for the quick reply.

Your HUB stats look ok, upstream and downstream power levels a touch high, but in spec.

I hope for your sake it isn't, however the BQM (Make sure you create one!) may show congestion in your area.

[Madras]

So not much I can do? right?

We need to prove it's congestion first, using the BQM.

It could be something else.

[Madras]

Thanks for clarifying.

I've signed up to Thinkbroadband and set up a BQM - I guessing 24hrs before I have usable data?
