Upgraded to Gig1 but intermittent connection.

[Anonymous]

I upgraded my m600 connection to gig1 today. My hub 4 arrived at 5.30pm and I connected it. Shortly after I received my text messages to say the signal had been sent and the upgrade was complete. 

I ran a speed test and was getting 945mbits. So no issue with speed. 

I do have an issue with the connection dropping. My pc shows a connection for a few seconds to a minute then the connection drops. Games disconnect and Web pages fail to load. My son also reports this on his pc and his xbox. The Internet icon on my pc shows no connection as confirmation of an issue. I've tried rebooting the pc and also turning off power saving on the ethernet adapter. 

When the connection is down I cannot even seem to connect to the router using its ip address. 

The light around the top of the hub stays a constant white at all times which also suggests to me the issue is with the hub and not the fibre signal entering the hub but I'm just guessing. 

Then the connection will come back up. Work OK for a few seconds to a minute and it repeats. 

I'd guess at a faulty router if I cannot even access its ip address but if anyone else has any suggestions I'd love some help please. 

My son is in the army. Home for a week from Cyprus and now he can't even play his game with his mates. 😕

I've left it for a couple of hours to see if it needs to stabilise. I also power cycled the router. It hasnt stabilised and power cycling didn't help. I've tried a different ethernet cable too. I've tried a cat 5 and cat 6. 

I ran checks on the router and the only issue it found was the telephone wasn't connected. 

I'd really appreciate some help please. Especially as my wife works from home too.

Thank you all. Take care

check the coax is tight at the wall and the hub - was there any attenuators on the old hub - small barrel shaped connector between the coax and the hub - if there was did you fit them on the new hub

try a full reset of the hub - hold the button a good 30 sec

try a test with the hub in modem more - only one device will work but see it the connection is more stable

log into hub3/4 - 192.168.0.1 [or 192.168.100.1 if in modem mode] - DON'T SIGN IN, click - click router status [centre of screen] - and post the downstream and upstream figures - to see those press on the grey buttons/boxes labelled - upstream - downstream

Tightening the coaxial at the hub did nothing. Wall side was tight. I'm working 7 until 2 but I'll try the rest ahem I get in. Thanks.

Problems still persisting, my son reports issues every few seconds up until he gave up at midnight, ive had a few disconnections this morning so far and only been on a few minutes, previous m600 on hub3 was rock solid, no issues in years. Any help appreciated as its ruining my sons army leave and my wife is getting lots of issues trying to work from home. Thanks.

Apologies for the constant replies to myself but i cant see the edit function, just as a side note, when i woke, uptime was 7h 35mins so the connection itself isnt dropping , if that makes sense 

[-tony-]

edit function is only live for 15 minutes - might be 30 but after that its disabled

levels look fine apart from pre rs errors - not sure if what you see is a bug - i get the same on my hub4 and if i close the page for 192.168.0.1 and start again i get a completely different set of of numbers - others just get zero whatever happens so what you are seeing might be an snr fault or it may net be - VM will have to confirm either way

the uptime is interesting - i assume in hat time no one was using the connection so its not 100% known if it dropped to a device but it could be that its a device or cable problem

reseat all the lan cables as a first step - if that does not help then remove a device at a time or try one device with the hub in modem mode for a while - from the history up to now it should not take long to drop - or not

sat up a bqm if you have not already and post a link

It's definitely not right. Constant lag on the directly wired pc and constant disconnects on the others. Is it possible the hub could be faulty? What's a BQM? Thanks.

I've ordered 4 new cat 6 cables and I'll swap all ethernet connections out and try modem mode when I get in. Thanks.
