broadband - problems since router

frugglewump

I have broadband via telewest connected from the cable modem to a router (Sitecom DC202v5 cable router). Since the router was put in I have random, but not infrequent drops in the connection.

Whilst this is merely annoying on the main machine when running pandora it is crippling on my work laptop which requires a VPN (cisco v4.0.1) in order to be able to use my home broadband, due to the admin locking users out of the proxy settings.

In fact simply during the time it took to type this + 5 mins quick forum search I've had to re-enable the lan & reconnect the VPN twice.

Is this a problem with the broadband? the router? or just something I'll have to live with if I want to use this laptop?

Difficult to answer, it could be any of those. Check to see if there is a firmware upgrade for the router.

One thing you could try is to reduce the MTU on the router to 1400, as VPN adds extra data to each packet to encrypt it, which then makes the packet too big with standard settings, which causes retransmission of data. which slows things down.

The cisco client comes with an mtu tweaker to change the work laptop, and you can use this to change the home PC.

ive also had lots of problems with telewest just alately - drop of connection and that, but, it didnt happen once i set the router up for my laptop - there does seem to be an issue with their services and them not really knowing how to do it right...

the engineer is coming out for the 5th time tomorrow so fingers crossed....

at this moment i cannot access hotmail or even some webpages like my bank.....but, before they changed the wire yesterday i could.....arghghhghg

i had the same problem with telewest last week magoogy and the only way i got it fixed was to complain every day until a got a ring back from a manager not teamleader , they said it was my pc put it was the ubr fault and afecting 1500 poeple and they want you to do loads of tests which they can do at there end ,they do not support routers so when you ring make shaw the modem is plug into the pc not the router if it do's the same on it ,
