Hi guys, new to the forums so firstly a hello to everyone =]
I've researched a bit over this forum and haven't found my situation so I was wondering if anyone can help (if I've missed a thread, sorry.)

I have;
1x PC [XP SP2]
1x Laptop [XP SP2]
Virgin Media Cable Broadband 2Meg [Phone/TV/Internet]
Belkin Wireless G Cable Router

PC connected to the Cable Modem works perfectly, never has latency issues, I can play WoW and FlyFF at the same time without lag.
Bought the Router yesterday because my other half [laptop] needed internet connection. Installed the router, exactly to instructions on the CD, hooked PC up to it and was 'ok'. (Cable Modem into Router, PC into Router via Ethernet) Thought there was a slight speed drop but disregarded it. I connected the laptop, also via Ethernet (it's an older laptop without built in WLAN). This is how we wanted it, for time being, until we buy the proper laptop with wireless (hence buying a wireless capable router). Both PCs could browse the internet at the same time, albeit slowly, so connectivity wasn't an issue.
HOWEVER [this is the fun bit

]
Laptop's MSN Messenger dropped connection constantly. Literally every 2-3 minutes.
PC started doing the same;
WoW was reporting latency of 1500-2100ms (compared to about 110 before router went in)
PC's MSN started dopping as soon as I fired it up.
I thought; maybe it's just because there are two machines using the connection now; so I unplugged the laptop, disconnected it from the router, and expected a speed boost and no more latency issues.
WRONG. The issues remained. After about 10 minutes of this, I got so wound up that I just bypassed the router and went PC-Modem again, and bingo, all issues are gone... Except we're back to square one and the laptop is internet-less.

I'm not exactly a whizz with these things, but a 2MB connection, shared between 2 people, neither of which are using wireless, at 11pm Sunday [to avoid any peak traffic], should not have an issue with playing a game on one, and an MSN Messenger conversation on the other simultaneously, right?
Hoping anyone can advise,
DF
