Maximum PC

Hey guys.. I'm having an issue with LAG while playing games through LAN. Right now the problem is Borderlands 2.

I host the game on my PC..
I5-2500K @ 4.5
Gigabyte Z68X-UD4-B3
Corsair Vengeance 8GB DDR3 1600
XFX 6950 XXX 1GB @ 1000 / 1500
AData 64GB SSD; 2x WD Black 750GB RAID 0
Win7 Pro 64
Can't think of the Brand / Model of the network card but it is a dual antenna Wireless N.

My sons pc is:
Athlon X3 720
Gigabyte GA-MA785G-US2H
Kingston HyperX 4GB DDR2 1066
BFG 9800GT HDMI
Linksys WUSB54GSC-4A (Wireless G)

The router is Cisco-Linksys WRT160N-RM Wireless-N Router with DD-WRT.

When he connects to my game the lag is unbearable. He constantly freezes and there is at least a one second delay when jumping, firing, etc.. I did order a Wireless N adapter just in case it could be that, although I would think G would be enough.. maybe I'm wrong. Think it's the adapter or could it be something else?

Did you try pinging from his computer to another device on the network? If his pings are normal, it just isolates it to the game.

I didn't try pinging but I will tonight. It happened with Borderlands one as well but those are the only two games we had attempted.

If his computer isn't powerful enough to host a lan game, that will cause lag as well.

I host the games with my PC. Either PC should be powerful enough to host though.

I tried pinging and I have excellent response times, 2-3ms.

Is everyone fully patched?

Nasty

Yes we are. I have two Steam accounts so we can co-op together.

Your sons video card is out of date for that game, have him dial out all the eye candy, go down in resolution to 1024X768 and try it again.

Nasty

Already done that. 1024x768 is his monitors resolution and he can play it without issue at low - medium settings. I'm scratching my head on this one lol.

Are you connecting WiFi or Cat5e? If Wifi, try a crossover cable.

Are you connecting the two computers together using Cat5e? You should be using a Crossover cable in this case unless your nics support crossover already and can use just Cat5e.

Nasty

Wireless and I'm not connecting directly to the pc, both PC's are connected to the router.

Do you have sharing setup?

Do you have the proper ports open for the game, you may have to go to the game site to find out which ports to open in the router.

Nasty

I have the ports for BL1 shared.. I would think it's the same for BL2 but I'll check on that.

Changing the NIC fixed the issue. I guess Wireless G isn't enough bandwidth for the game.. dunno.

....well, at least you found the issue and fixed it...

Nasty

Yea.. honestly I didn't think it would be the card.. maybe it was a combination of the Wireless G and the fact it was an external usb adapter.
