Internet incompatability problem

[Jelly]

My desktop keeps on having trouble with my intternet. Since I have had this ISP I have been having trouble staying connected. I have gotten new equipment and everything from my ISP, and still have the same problems.
For a week the internet ran fine, but suddenly I'm having trouble again. Is there some way that a piece of hardware in my computer may have a compatability problem with my Internet service?
I have Wireless Radio internet.
Gigabyte K8 Triton
Athlon 64 3000+
1024 RAM
40 gig hd
Geforce 6800 GT
m-audio Revolution 7.1

Funny thing is, my dad's comcast broadband seemed to work fine. The internet didn't run good on my old computer. The only pieces of hardware that is on my new computer from the old are the RAM and the hard drive, but the hard drive has been wiped multiple times since then.

God damnit

may have a compatability problem with my Internet service?

if you get connected some of the time No

what flavor of internet do you have (example dial-up, dsl, cable ect...)

What modem and router/wireless-access point do you have?

My ISP is Falcon WIreless.
It is Radio-internet. A Dish picks up a radio signal from an antennae and automatically assigns it an IP, so there are no modems attached. From the dish a CAT5 cable runs into my house and ends in an RJ-45 male plug. That male plug plugs into a femal power adapter which sends power up to the dish, from the power adapter a short black "jumper" ends in an RJ-45 male plug, and that plugs into my female ethernet port on my computer. I have already tried a NIC, and the same thing happens.

To start with, you probably ought to slap a budget router between your computer and your dish equipment, if you don't have one already. Doesn't have to be fancy, Linksys BEFSR-series or Netgear RP614 would run you around $30-40 and provide a perimeter firewall against worm/hack attacks from the Internet.

Other than that, I don't know, is a different type of Internet connection an option for you? If the problem is local, I'd tend to start with antivirus/antispyware scans and a hard look at the firewall situation. What's your protection at the moment on that stuff?

Well, if when you use Comcast and it works without any problems, but when you use the radio internet, you have problems, sounds like it's the radio internet. I'm not familiar with it, but it sounds like it's DHCP... if so, when it doesn't work, have you tried pinging the gateway? Do you get a response? If you do, have you tried pinging a website? Do you get 100% PL, or high PL with high pings?

And is it like satellite where it requires a dialup modem as well? If so, you may want to try changing dialup service temporarily just to see whether that's the cause.

I use Sygate Firewall, but I have turned it off once or twice because it was blocking my brother and my crossover cable connection.

I have tried pinging routers that I no longer have and have gotten no packet loss. How would I ping a website?

Also, it had been running fine for a week, then it starts having trouble again within the hour of hooking up a crossover cable with my brother. Some setting change causes it to go out of wack, it seems. Maybe

Maybe your brother's computer has worms/viruses. What antivirus software are you using? And if you're turning off your firewall and don't have a router, your system had better be up on its patches and hardened, if this ISP is like other broadband setups, because that is exposing your system to a world full of worms and hacker kiddies.

Maybe he has poor signal quality from the isp

My brother's laptop was brand new, and hadn't even been used for 24 hours. My system has service pack 2 and is updated fully, at least was fully updated 2 weeks ago.

I dont think its signal strength because it wont work on my desktop, but has been working perfectly on my old-ass laptop with windows 98, and no updates.

Right now, I am back on the problematic desktop, and my internet is working fine. So you see, this problem happens on and off.
