Re: Just Turned Off Firewall ! Should I ?
A router performs firewall like duties anyway, that's one of the added bonuses of NAT(network address translation), in that your PC is not visible from the internet. And the only things that can come from the outside are either a) applications/ports you have forwarded to you PC, or b) applications/ports your PC has instigated communication on.

The firewall on/off feature probably enables things like SPI(statefull packet inspection), and may also be able to detect and prevent SYN/DDOS attacks etc.

It's up to you in the end, however, if the router firewall is slowing internet access down then I would try and narrow it down to more than just toggleing the thing either on or off as it sounds more like a misconfiguation to me.. Does it have more configuration options, if so, try switching these on or off first.
