I use InSSIDer to find the best channel. The only one that works well is channel 11, all others get stupidly low speeds of 5.5mbps - 40mbps whereas channel 11 works @ 300.

I had zero wireless issues with my 3700, it jsut this pos shub.
I got a better performance using 2.4ghz at 145mbps. 300mbps only worked with 5ghz.

Mind you it's all irrevalent as the only solution to superhub probems is modem mode in conjunction with a decent wireless router.

Good luck with it anyway.

Re: WTF is up with my connection?

I having exactly the same issue today the internet connection drops every 3-5 minutes, if the VM can't provide 50MB when they talking crap about boosting the speed for customers, as they don't have enough network capacity - overselling and misleading is their sales technique - need to contact Trading Standards as their service is not up to service level!

My modem shows constantly the following error logs:

Re: WTF is up with my connection?

Hi Alexander

Two points:

1/
Can we please see the full modem stats including the Operational Configuration? That may provide some correlating information.

2/
In your opinion or as a result of observation, are those messages occuring during a modem reboot? It looks to me that the are and that the stats might point to the cause.

Cheers

Not during modem reboot, also idle mode, as this issue was the whole day, the modem was rebooted only 5 times.

The cable modem event log is normally full with the above posted critical errors and warnings.

Re: WTF is up with my connection?

The stats are nominal. Which makes it all the more difficult to diagnose.

In the event log, wherever a MIMO event occurs, that's a reboot. The B-INIT-RNG event is also a reboot, which will have been initiated from the VM end if the modem has lost contact with the CMTS.

So that looks to me to be in the network somewhere. You might care to call support in office hours and keep trying till you get a UK agent. They can jump on and see what's happening.

Re: WTF is up with my connection?

Hope I am not speaking too soon, but my complaining seems to have paid off. Also running @ 145mbps seems to have solved the wireless issue. I have not been suffering as much latency issues, although as you can see from my live graph I lost internet today for a bit. Just did a speedtest and got full 50mbps.

Wonder what, if anything, they did? It seemed to get better after my connection died on the night of my last complaint from 12am - 6am? Any ideas?

Not yet, they tried to deliver it today but was out. So need to call to arrange it to be redelivered.

Re: WTF is up with my connection?

few things you need to know...

for sure you need to get rid of that power adapter youve currently got connected.

there'll be a new SH within the package, you may as well install from fresh, both the new SH and adapter.

send back your old SH, there'll be a Royal pre paid sticker within the package, should be, might not be. but that adapter you've got for the VMNG, either mark it clearly so VM know its incorrect when they open the return or throw the adapter away and just send back your current SH.

Oh right, so it is a new SH? Wondered why I needed to sign for it! Cheers mate.
