    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. 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. The problem happened both when using my router at my house and one at my friend's house which uses an entirely different router. The problem seems with my laptop and not specific to any one router.

    EDIT: Not sure it it matters at all, but the laptop I just got is a Samsung series 7 laptop and I use Google Chrome.

    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.

    Here's the results from using ipconfig /all if it helps

    Make sure you have the latest wireless driver from Samsung's web site.

    What encryption are you using?

    I just made sure the drivers were updated with Samsung's. There's a software update program that I used to reinstall the newest one for the wireless. It didn't help the problem at all though.

    The encryption for the router is WPA2-PSK.

    Also some web pages just don't load properly at all anymore. For example I can't even use youtube anymore because it looks like this:

    EDIT: Clearing the cache temporarily solves this but then the problem just comes back again later.

    Also this is what pinging google.com typically looks like while the computer is idle:

    Now if I were to be in a game, that area with the higher pings would result in a huge lag spike, they happen frequently enough to make any type of game unplayable. Typically while in a game though they also occur much more frequently and can reach much higher pings than that, going up to well over 1k or taking so long that the request just times out completely.

    Try with the router's encryption disabled. If that works OK then try WPA-PSK (not WPA2) encryption.

    While normally it's best to use the laptop manufacturer's wireless driver (in case they needed to modify the original driver to make it work in their system) try the one directly from Intel's web site. If that doesn't help go back to Samsung's driver and check at least once a week to see if they update it.

    Tried disabling the encryption but that didn't help. Neither did switching drivers with Intel's.

    Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 7 or Vista I prefer to use the built-in Snipping Tool.

    Identify your network if you are not connected at the time of the screen shot.

    Is anything missing from that SS that you need?

    The signal strength is too weak for a reliable connection. In the same room with the router see what Xirrus shows and see how your connection behaves.

    When moving closer ping times in general are around 1-2ms faster, but the problem of it spiking up randomly is still there, moving closer didn't change it.

    It certainly changed the signal strength. But the variance there indicates a problem with the router, the adapter or its driver, or some unseen interference (e.g., from a 2.4 Ghz cordless phone or baby monitor).
