Network/internet keeps dropping.

Hi,

first time i've posted, so if in the wrong area, please forgive me...

i'm running windows vista, and have been for the last year. the proble
i have is that since i have updated to SP1, my net connection keep
dropping. the network symbol has a '!' over it and i have to click o
diagnose and repair and reset the network adapter. this happens mostl
when browsing the internet (on Firefox or IE) but sometimes happen
when i first start an online game up (cod or war etc).

i use a netgear router and have done for the past 3 years and never ha
a problem. the net connection its self (on the router) does not drop an
therefore it has to be a problem with my computer (tested this whil
having 2 computers running at same time and the connection only droppe
on the problem computer). when the connection drops, i cannot ping m
router (no lights on the router change - still states the net i
connected).

I've tried updating my Rhine II Fast Ethernet Adapter. however whe
attempting to do this through Device Manager, it says its full
up-to-date. even though the driver date is 17/4/07. I've attempted t
update this manually, but i either have to pay for it or I'm asked t
download device detective and asked to pay for the download... ther
are no drivers on the windows updates for this... or at least don'
appear on the list.

can someone please help me here cos its getting on my nerves and th
only solution i can see so far is to uninstall SP1...

Thanks for any reply's.

JM
