Infinity 'drops' after large/fast download


[link to this post]
 
I've had infinity for about 4 weeks now, and whilst it's great n'all that, I'm getting rather narked by my connection dropping after any large download...

After maxxing out the connection on a download (just done 2.5Gb) the connection drops. If I reboot the router all is well again.

Any ideas?

Overheating?

Wireless or ethernet connection?

Presume you are talking about the Home Hub 3

The modem is connected via Ethernet to a Draytek Vigor 2820n (WAN2) running latest firmware. I haven't tried the HomeHub, and don't really want to.

My MTU is set as 1442 and not 1492, could this course the problem?

Do you mean 2.5 GB ?

That will mean the modem running solidly for around 12 minutes or longer. Given that the chips run warm even in idle running the line interface and demodulator at over 50% of capacity for that length of time will certainly heat it up quite considerably and as BatBoy suggests - overheating may well be the cause.

It is not just the Huawei modem that suffers, I have heard of other makes suffering too.

edit to add:

I will get a thermal probe inside my modem, obtain the quiescent temperature of the heat sink and then run a 1GB download, check the temperature, then repeat.

MTU on computer or router?

This may be a factor if there is a mismatch e.g. PC is higher then the router will be very busy shuffling bytes around.

With an issue like this, you need to double check its not router based.

Does the Openreach modem show the VDSL sync light resyncing?

Earlier today I did about 4 GB of download and found the heatsink temperature went up to 55 deg C - that is in free air, uncased. A little too hot for my liking but mine did not fall over - although when I rapidly force air cooled the heatsink down to 20 deg C it fell over and needed a reboot. So maybe it is heat related.

Are you still using a 2V modem ?

Ok, I unlocked my modem (SP10 - Rev. 2B) and other than a sizeable amount of FEC/HEC errors (that don't increase when my "connection drops" the modem appears to remain connected.

The problem appears to be torrent related... one torrent or multiple torrents and my entire connection goes slow/gives the impression it's dropped for 10 minutes...

I never had any problems previously with Sky & Torrents so doubt the router is to blame...

I'm aware of people complaining of slow downloads of torrents, but noone seems to have theirs drop when downloading torrents...
