So,I had this problem connecting to the internet with my desktop computer.
I got a lot of suggestions and I tried to follow them one by one.
I tried Stryder's suggestion of turning off the modem and the computer and waiting.It didn't work.
I uninstalled and reinstalled my modem a few times,like Dywyddyr said.Didn't work.
I was actually about to reinstall windows(XP) and see if it works,before I decided to give the UPS a try.And like magic,the internet connection is working just fine,now that I am runnning the PC with the UPS.
My question is why?What's the connection?
And what is this Surge Protection thing?It is written near my UPS sockets.And it was something that Stryder was talking about.
And I am actually planning on getting a new UPS,but if I can't connect to the internet without this particular UPS then that's a big problem.What should I do?

As has been said UPS just means "Uninterrupted Power Supply". It's basically just a battery system that sits between your power input and your computer. Such supplies are used mostly with server systems that require limited disruption (0.05% of the time to be precise)
The UPS system will syphon off power over time and store it in the backup battery, during this period it will power the computer and whatever else is connected directly.
My explaination about surge protection, is that if your UPS pack is location on an extension lead with Surge protect or the like, the devices plus battery when turned on will attempt to take a large charge all at the same time (They basically require a surge in the power requirements). The Surge protection is likely to stop this from occuring, which causes an undercharge, in the sense that the power required isn't recieved.
This in turn can knock out the UPS system from charging, which is not good in an environment where it needs to be uninterrupted. It's suggested that if you use Surge Protected sockets with UPS systems that you test it extensively to make sure they work together rather than against each other.
What could have been causing your modem problem is perhaps a Short (I'm guessing you are US based using a two pinned 120V connection with no EARTH cable. It's possible a charge is interfering with the actual computer or modem. The only potential fix here is either to learn how to build your own earthing method or use premade earth adapters.)
So you could try that. As for UPS replacements, You shouldn't have any problems with the replacement as long as you make sure it takes the SAME input and outputs the same output in regards to volts and Amperage. For the most part this is an industrial standard that only has the deviation of physical location (US UPS will be different from European slightly.)
The only other potential is if your Modem is a WIRELESS one, and that it's situated too near the UPS pack. That might cause interference because of the power fluctations or the internal shielding, so move them apart from one another.
