The wifi for my desktop is fine during the day, and crap at night.

Yes, but I seriously don't see why this is so. There are only like 3-4 wifi networks around me. I've had better wifi reception in places where there were at least 20 detectable wifi networks. For some reason, only my desktop has it this bad. All the other devices managed to get at least 5mbps download speed, out of the 10mbps I've been paying for, but this is only at night. It gets a full 10mbps during a day, regardless of what device I use.

PS, I've already gotten a replacement for the router and optimized all the settings. Still no go.

if it's happening only at night, i'd look at what other wireless items are on at night, these could be interfereing with your signal.

microwaves, radio communications systems (like walki talki's, baby monitors, wireless phones etc) could be running on the same wavelength as your wifi adapter and causing the issue.

That's what I thought, too. But I can't find anything that could be interfering with my wifi adapter. The only walky-talky I had was broken and I left it at my old office, no baby monitors, no wireless phones.

I have a really powerful fan that could be causing the EMI, but it's been there for a year already and this problem has only started a month or so ago.

The only new major electronic I have in the house is a hot/cold water dispenser, and it's turned on 24/7. Yet, my internet seems to be affected only at night.

It's possible when people get home from work they turn on all their devices that may produce interference but may not be wireless routers. In addition, if a router isn't broadcasting its SSID you wouldn't see it, so there may be a half a dozen more routers around you that you aren't aware of.

BTW cordless phones sometimes operate on the same frequency of wireless routers. Try changing the channel your router is operating on. If it's set to the default and everyone around you leaves it on the default as well, that could be an issue.

A wired connection by ethernet didn't help either...

Then it's likely your neighbors share some local broadband. Cable internet, for example, is considered shared, but DSL is not. Speedwise, I tend to find cable is faster than DSL. I would try contacting your internet provider and see if they have any input.

You could try changing your DNS settings. I did this recently for my aunt who was having problems with her local provider. Google DNS is 8.8.8.8/8.8.4.4, but you could try OpenDNS.

I already checked, this DSL isn't a shared thing.

So, what settings do I use for my DNS settings?

It's also possible your PC needs a clean out, it could be so cluttered with images and information it can't handle it when things get busy, your settings might not be optimum either, and that depends on what you are running and how old the system is

The system was bought last year, March. DIYed with medium-high end parts for gaming and has Windows 7 Ultimate x64. Plays BF3 like a champ on high settings while downloading big files and the usual Facebook stuff I do. But at night, it barely manages to keep a stable connection to last me in-game for like 10 minutes while downloading a text file at around 20KBps. :(

Try what @roguekiller23231 said and also, you probably already did this but move the access point closer to you if nothing helps. I mean my laptop is all the way in my room which is about 70-80 feet from the access point and I get crap service. Moving it around 10 feet makes a HUGE difference because I get from 5-10mb down to 10-20 down.

The router is only about 10ft away from my PC.

Maybe there are more people in your area using the internet at night causing the network to be congested. I know that happens with Bright House in my area. Internet slows down a little at peak times.

Like I said, it's not Cable. I'm running ADSL+, and it's bearable on my other laptops and devices but not exactly this one desktop. Hell, I even tried bridging a laptop which had almost perfect wifi connection to the router, to my desktop via an ethernet cable AND the other way round. This desktop kept having slow and unstable internet connections.

I'm thinking it could be a software issue somewhere, but I can't freaking find it.

(Jun 25 '12 at 11:13) Billy Aoki

Why software? If it's just one machine hardware would seem the more obvious place to start. How old's the network card?
