It’s been superb. I’ve read horror stories about Comcast, but I’ve got nothing but good things to say about the speed. I haven’t looked at ping times too closely…but everything’s been smooth online. I’ve played everything from FPS to RTS to racing games and nothing has given me problems.
I’ve had no service outages save maybe a five minute downtime at like 2AM one time. The biggest problem was getting everything working in the first place. It took over a week for me to get an IP and for things to finally be right. Other than that…it’s all roses.
Since I am just south of you in MD and have also had Comcast service I will give you my impression of Comcast. When it is on it is fast as hell and I always was able to find good pinging servers. However over the 6 months I had it, we had a 24 hour outage and a couple of good 4 hour outages. I haven’t had these problems with my current (Verizon) or previous (RIP Northpoint – god damn they ruled) DSL lines. Despite my problems with Comcast, I would still rather have it than nothing because it is quite fast when it is working. I think you will love it compared with dial-up. Once you have broadband you can never go back.
One of the greatest parts of cable is the ability to share over multiple computers, and not have crap to worry about. Make sure you get a hub, or at least set up a linux boxen to share the access across the house.
My main problem with dialup would be the knock down drag out fights we would have about who would get to use the phone.
A broadband router, preferably with a built-in Ethernet switch, is cheaper than even a Linux box, and won’t use as much power. Dlink, Netgear and Linksys all make decent ones with built-in firewalls. Some even offer stateful packet inspection for better security.
Totally, I found a refurbed D-Link Router with a 4 port switch and a print server for $40. Gives me far less trouble than my old NAT 32 setup. The only problem I had was, being used, it had a password set that I couldn’t possibly have known. I could never get the direct terminal connection over null modem cable thing, which is supposed to give you a way to reset the password, to work. But I wrote D-Link tech support and they told me the super-secret way to wipe out and reset the password (the method in the manual didn’t work).
