netgear broadband.

hiya i got a advent modena m100 for christmas and it connects fine to upc broadband. but the house im living in has dgn 3500 and when i turn on computer it knocks off internet for everyone and the red light where the power icon turns red. has anyone got any suggestions as to wat the problem is

If I understand when you switch on your laptop the DGN3500 fails with a red power light. Are the units connected by cable or wirelessly?

its wireless everyone else in the house can cannot fine.

Can you switch off wireless on your laptop? If so, when you do this does the DGN 3500 still fail? If you move the laptop further away does the DGN 3500 still fail?

Hello,

Im not familiar with that model of router, but the problem seems familiar to something i've seen once before. Basically the dgn3500 is tripping out when there are to many clients connected wirelessly using 802.11n (150-300mb connection speeds).

It seems to draw to much power in the high speed modes with lots of wireless clients. What I ended up doing was switching it to 802.11g (54mb).
Maybe its whats happening with you, ask who ever has access to the router to downgrade the wifi to 802.11g (54mb) and see if the problem continues

That would seem to account for the symptoms the OP is seeing. If so I'd say it's a bit of a design fault.

It's a Netgear... probably a marginal power brick.

Still a design fault. Never had a problem with my DG834G.

True, but a meatier power brick would be an easy way to check it, if there's one around on another piece of kit.

A mate got a Belkin that does the same thing, i wonder if that have the same problem? He don't use it now as it was causing all sorts of problems with not allowing him to acess some sites and not allowing windows to update, I tried all ways, opening ports on the belkin, but gave up.
Anyway he had the problem that when someone else tried to connect the router would reset.

He got a old Netgear 834 just normal ADSL and it does a better job than the up to date Belkin.
