New laptop has much worse range for wireless

So recently I've gotten a new laptop, but now when I try to connect to out wireless internet from my room it has an extremely weak signal and will constantly suffer from constant disconnects and spikes in latency, which seem to go away after moving right next to the router. Occasionally it causes web pages to load incorrectly and makes games unplayable when they were fine before and videos will take a long time to load. The new laptop has a different network adapter ( Intel Centrino Advanced-M 6235 ) and has Windows 8 installed instead of Windows 7 like my old laptop had.

When trying to ping google.com it will usually stay at around 31ms but will occaisonally jump to around something much higher like 300ms or so for a few pings then go back to normal. If trying to do something like playing a game then it can start shooting all the way up to over 1000-2000 and will sometimes just have the request time out. Using tracert to google.com gives very different results each time

You can try changing the channel on the router and if you have a dual band router you can change each band seperetly. With the new laptops adapter you may be using the higher 5 ghz N band and so you could start with that and just take it off auto and select one of the channels , go with one higher then the lowest because that's what the auto setting was most likely using.

Hm, none of those things seemed to have helped. The issue I'm having goes away if I get right up close next to the router, but I want to be using it from farther away in my room, which I was able to do on my old computer but can't now.

So after trying to move closer a bit more it turns out that even at close range it will still have issues connecting, but the problems dont seem to be QUITE as bad. The connection usually isn't problematic when just web browsing in general, but when trying to do something that requires more resources like playing a game it'll have ridiculously bad latency spikes, going up to more than 1000 ping at times. It makes them all entirely unplayable (even when up close to the router), even though my old computer had no connectivity issues like this at all.

Also when using wired, there are no connection issues at all, it's only with the wireless, but using wired internet isn't going to be an option for me.

What brand and model of router do you have. By using wired and having no issues at all that narrows it down to the wireless.
Are there other devices and computers connected by wireless to the router and are any of them having issues ? It might be that your new wireless adapter is either defective or not compatible with your router.

There are other computers/phones/etc. that can connect to the router just fine. My old computer never had issues, for example, it's only this new one that's having problems. I tried connecting to a different wireless router and had issues with that one as well. The drivers on my network adapter are updated though, and I tried uninstalling and reinstalling it but it hasn't helped. It's not like it can't connect at all, it's just that the connection that I'm getting is extremely poor comapared to what every other device in the house is getting.

There is also the possability that the wireless adapter is defective and you have ruled out the router and the wired connection and all things now point directly to that wirekess adapter. So replacing it may now be your only option.
