Upload only 249Kbps (should be 25Mbps)

[pks01]

Dire upload speeds all day today. Downloads are fine, but Virgin's speed test tool shows:

• Latency 150ms
• Jitter 184ms
• Download 276Mbps
• Upload 249Kbps

The upload is a mere 1/100 of the 25Mbps rate promised in my package.

Jitter is apparently appalling, and latency is very poor too.

I have no idea how long it has been this slow, as I only checked today.

How do I get this fixed?

I have done a hard reset on the Hub3 several times during the day, but that has not made any difference.

Check for local issues:

My own reported outage is the only thing showing.

What do you mean?

The large latency & jitter figures look like a test over WI-Fi.

How to get stats from a VM hub (no need to logon to the hub)

Open a web browser and go to 192.168.0.1 router mode or 192.168.100.1 modem mode

• Click on the “> Check router status” button
• Click on the “Downstream” tab, copy the text and paste into your reply, do not take a screen shot
• Click on the “Upstream” tab, copy the text and paste into your reply
• Click on the “Networking” tab, copy the text and paste into your reply.
• Do NOT post photos or screen shots they will be rejected as they contain MAC addresses. The board software will automatically change MAC addresses to **:** if done as above.

NB - these are from my desktop, and therefore hardwired as there is no WiFi on the machine.

[carl_pearce · Accepted solution]

Power levels, mostly, too high on the downstream, and QAM values on the upstream show why you are seeing a large number of T3 timeouts, and will be the reason why you have a slow upload speed.

Needs looking into further by VM.
