What else could it be?
im at wits end now, since August my modem has been rebooting randomly and i have found out reciently a few others locally have the same problem....

I have 2 engineers here after Secondline support said that its a problem with high power on upstream as it spikes at 59dBmv and all they claimed they can do is "Change my modem" and ive had 3 modems now since November of last year.

Now second line support are saying they cant see any problems on my UBR or network they asked the local network team to check it out and they are also saying they cant find any problems yet its STILL happening, here are some of the logs.... As i said there are other locals ive spoken to having the same issue.

Re: What else could it be?
Perhaps the engineer arriving between 12pm and 4pm tomorrow will be able to advise further or escalate the issue to local networks. See what he has to say.

Given you've no additional information I'm not sure what anyone here can tell you that hasn't already been said. Power adjustments indicate amplifier issues usually.

Re: What else could it be?
Yes, assaulting a technician will get it all fixed for you.

I'm getting lost now, I thought your power level and slow speed issues were occurring when you were on the old kit.
Now you're on the new kit, you're getting random reboots but no power level or slow speed issues.
You need to seperate the two sets of problems.

Re: What else could it be?
basically i was having modem reboots cos of high power levels and they changed my modem which kicked me off the new kit onto the old kit, and not only did my reboots continue but it caused slow speeds due to port utilization. They then put me back on the new kit which solved that but im STILL! getting modem reboots due to what they say is high power upstream.

Re: What else could it be?
well the engineer here rang a person who is part of the network team here in swansea who is a friend of his and is also on this site and i am in contact with myself and have been sending him my modem logs. He said that he has been passing the logs on further up the chain as its a DCHP server issue and the people further up the chain claim its impossible and they r stuck in a deadlock while im having to put up with a connection that has more ups and downs than Monica Lewinskis knickers!

Re: What else could it be?
fancy posting a public IP you've had in the last couple of months so I can take a look

any idea what UBR your on?

Just had a brain flash - post the MAC of your device plugged in behind the modem NOT YOUR MODEMS MAC ADDRESS and i can use that to check dhcp logs. That way I can look at you connection without compromising anything

Re: What else could it be?
the mac address of the network card plugged into the modem then =)

go to run>cmd>ipconfig /all - look at the bottom of this ifno and your mac will be there. Don't worry, it won't allow anyone access to you machine or anything, itll just mean i can take a look at your connection

Re: What else could it be?
yup, im tech support

I actually haven't had much exposure to the new UBR's hence why im interested in this problem.

Id like to know if their are problems with the new kit before it starts affecting the customers that I deal with =)
