I used to have cellular Internet service as well. If you can move your router around (every slight rotation, and even changing where it is by just a millimeter can make a significant difference) and manage to squeeze out about 4 Mbps down and at least 300 kbps up when you run your connection test, then you should be able to achieve a just barely acceptable connection. Also, unless you are somehow able to get a much better speed than this, you're gonna have to take drastic measures to reduce lag. Turn off the media server in the network options, and check and make sure Upnp is enabled. You'll have to mess with your router settings if it's not. You'll need to clear your cache at least once or twice daily, and you may want to switch your phone to airplane mode if you use it for the car lists, or turn it off completely, as receiving a text or phone call, even without the phone being connected to WiFi, will cause a lag spike, sometimes with enough lag to disconnect you from the room. Also, your connection speed can be influenced by the weather. Any time there was a storm over my place, I would find, at some point, that I would be unable to connect to the Internet at all, and my speed was generally slower if it was just very cloudy out.
Last time we raced, I didn't notice any issues, so I kinda think your better off than I was. I usually spent more time troubleshooting my connection than actually doing any online gaming before I upgraded. Btw, that rig looks awesome. Wish I had one.
If you ever find the better part of a grand lying about, I would definitely say the Obutto rig I have is totally worth it. Thing's like a tank -- shipping weight was 75 kilos I think. o_O Totally transforms the experience. Now if only a money fairy would crash into my house with about two grand so I could build the triple-screen PC sim that the rig desperately calls out for.
About internet speeds, before when I was racing against you guys, I was still on the fibreoptic lines in town, with a theoretical 100 Mps up and down. Out here on the farm, I was initially really worried because we were getting only about 8 up and 1 down, and I was getting annoying lag spikes and packet drops in the only other game I play online -- admittedly, a game with pretty bad netcode. Then it dropped to 4 up and about 300Kbps down, which is when we discovered that a bad storm had plastered the receiver against the roof so that it wasn't pointed anywhere near the transmitter up on the mountainside.
Once we got the ISP to fix it, it shot back up so that now, depending on the weather, I can get 20-30 down and 3-5 up, and the ping is comparable to the landline connexion in town. That's on my iMac using the wireless LAN, for what it's worth, and is about the same connexion speed that the PS3 would report in town. So now I'm mildly (but cautiously) optimistic that I'll be able to race again once I can get the rig set up, which will probably be this weekend. I'll be hardwired to the router, of course, but I expect there will be times where I'll be a little laggy or even unable to maintain a solid connexion, if the weather's crappy enough to cause radio interference.
I'll also probably have to schedule no-internet time with the rest of the family to minimize the chance of disastrous lag et cetera. In town, there were times I'd be hosting and racing with a torrent going on my computer, two other computers streaming HD video, and my tablet open to the car lists and the forum, with practically zero problems. Doubt I'll be able to do that here, though!
Anyway, here's to at least being able to attempt to race with you folks again soon!
If so, I'll be rusty as hell tho -- haven't turned a lap since I moved six weeks ago. I miss racing!!!
