We have an issue on a site which has had decent enough broadband service for the longest time. Over the past couple of weeks people have been complaining about "slow internet". It's got quite ratty the last few days.
I've run a lot of speed tests, I've tried different routers to ensure it's not just that.
This is on the Erskine exchange.
The router is showing SNR margin of 12 (11,12,13,14) and Attenuation around 48.
It was showing SNR around 4 until the provider changed that a few days ago.
The router is a Vigor 2820Vn
Typical speeds the last few days are around 4500 Kbits download, and almost always 138 Kbits upload. The router sync is showing 5208000 download and 190400 upload.
When it was showing SNR around 4 , the speedtests were returning wide variations between 2000 and 6800 download , and fairly constant around 220 upload. Router sync at that time was generally around 6912000 - 7360000 download while the upload varied a lot, 256000 to 416000
Does anyone have any words of wisdom on these results ?
When I've tried another modem and another router, the upload speed differs tremendously.
