Slow, unstable connection

I'm on a 100MB package and have to remote into my PC at work on a daily basis. My connection has never been great, however it has become markedly worse over the past few weeks, either providing me with a unworkable lag or kicking me out entirely. This is an issue with my broadband connection rather than on my work servers, as using my phone as a hotspot yields no issues.

Speedtest 2 (few mins later)

I'm connected to the router via an ethernet cable, so it's not a WiFi issue. Have tried restarting the router, re-seating all cables both inside and outside the house with no luck. 

While I appreciate there is heavy load on the network at the moment, and i'm not expecting sub-30 ping on a consistent basis, I do expect at least expect a stable, workable connection. Service status shows no issues in my area, as it always has. Any suggestions would be much appreciated. I'm at the end of my tether. I'm in the E18 postcode area if that is any use.

Re: Slow, unstable connection

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then Advanced Settings > Tools > Network Status.

Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again.

Use one post for each tab if you wish.

Please do not use screen shots.

A Guru will be along soon to decipher the info.

Re: Slow, unstable connection

What speeds do you get at >>  SamKnows << with a direct connection using a Cat 5E or better ethernet cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?

Then immediately after …

Can you Login to the Hub Settings and navigate to the Connected Devices page - what is the reported 'connection speed’ for the ethernet cable connected device you used for the speed test ?

Re: Slow, unstable connection

Thanks for the response. 

Reported speed for the ethernet device is 1000Mbps

Samknows result:
Latency: 68.5 ms
Jitter: 45.6 ms
Download: 31.2 Mbps
Upload: 878 Kbps

The only other device connected currently is the Macbook I am using to post this, which is connected via WiFi.

Re: Slow, unstable connection

Your >> BQM << is showing typical signs of over utilisation which is only to be expected with so many people schooling and working from home.

A good friend of the forums @Andruser has commented on the forum about similar problems to yours ...

Re: Slow, unstable connection

Thanks, I feared this may be the case. I'm on a rolling contract now, so it seems my only choice it moving to a different ISP. Appreciate the feedback.

Re: Slow, unstable connection

Change the hub to modem mode with a PC not downloading or uploading setup a new BQM and allow ICMP on windows firewall see if its any more better.
