Ever since I have upgraded to windows 7 I am convinced my internet is having connection issues. Upgrading from XP 32 to Windows 7 64 I have not changed anything with my service provider or hardware yet. Example being World of Warcraft, My connection to the server changed from 30-40 ms to 130-140 ms. Web pages will have a tendency to not load the first time, or second, or third but constant refreshes will sometimes load it instantly.

Its probably a very simple problem that I am just missing with Windows 7 but I don't know what it may be, any ideas?

Funny, I have this exact problem too, I upgraded from XP Pro 32 to 7 Ulitmate 32. The web page errors are always happening. I can't say anything about my pings (since this computer is crap), but my PS3 has always been giving me a DNS error and it takes several tries to connect to the network. I assumed that it was a faulty modem or wireless router, never got around to looking at it.

If your PS3 is also having connection issues, call your ISP.

@OP: Did you reformat? Install all the right drivers from your motherboard manufacturer?

Try using Googles DNS.

Try pointing your PC to Google's DNS (8.8.8.8 and 8.8.8.4) and see if it fixes your webpage issue. Not sure if it'll help with WoW.

I was going to do a screenshot but then I thought "If I do someone will just beat me to it" lulz.

Well its difficult to tell if my webpage problem has been fixed. My ping with WoW servers is easy to tell because its a number. (Which hasn't been fixed) Karmas anyway, the google DNS can't hurt to use anyway.

Im hoping for some sort of troubleshooting method, I might have a bad wire somewhere

Open up a command prompt and issue "netstat -e". If the "error" and "discard" counters are at zero, then you can rule out wiring.

Windows 7 is optimized for media transfer, not low latency gaming.
Large packet sizes, and waiting to send packets until the PC can combine multiple small packets into one large packet
= good for downloading, bad for gaming = Windows 7 default behavior

Adding two values to my registry, along with a couple other changes, dropped my latency in ICC-25 from 330ms to 130ms

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<Interface GUID>
(Where <Interface GUID> is your network adapter. The primary adapter will generally be the one with more values filled in, like DHCPDomain:<Your ISP>)

Add:
TcpAckFrequency REG_DWORD 1
TcpNoDelay REG_DWORD 1

By rightclick, NEW, DWORD(32bit), named as above, value 1

0 Discards and 0 Errors, but I think it's because my computer is using a wireless connection.

I never had the problem until the main computer had Win7 installed (as opposed to my one), the PS3 has the same symptoms as my computer, because after a few tries, it runs perfectly.

I'll try Google's DNS.

It worked in WoW? Does WoW actually transfer game state data via TCP?

Why would games use tcp?

I know nothing of how games transfer data but tcp is optimised for correct delivery rather than timely, I would've thought games us udp.

Fast real time requiring games use UDP. Some turn based and slow paced ones use TCP.

In which case the tcp no delay and ack frequency reg values wouldn't really affect it.

as well.

Will be upgrading to 7 one of these days, just as soon as I build a new compy.

Absolutely no idea about WoW but googling it up it sounds like WoW does use TCP.

Yes.

WoW doesn't rely on fast-twitch mouse movement.
Mashing one fire button really fast doesn't work. You have to mash a variety of buttons, in the right order, at the right time, once per 1.5 seconds.
Most of the data transfer in WoW is data, text, and packets requiring reliable delivery and specific ordering after delivery.

And a missed packet at a key moment can mean 25 people just wasted 10 minutes of time on a Boss fight.
UDP losing that key "cast ReallyBigHeal on BrickHeadtheTank" or "BrickHeadtheTank taunts off NewbSaucetheTank" packet = 25 people spend 10 minutes redoing everything they just did.

Hence using TCP rather than UDP

Looks right, as long as it's in the correct network adapter

Heh, I'm well aware of the differences between TCP and UDP. You can implement reliability on the session layer over UDP, and I've seen it done in other MMOs to alleviate TCP connection handling issues. I was asking because I weren't aware of the specific implementation in WoW.
