MY INTERNET HAS SUDDENLY GONE VERY BAD AFTER CASE CHANGE- DO I NEED A NEW WIRELESS CARD? Thanks

Hi,

First of all my PC specs are: (Prebuilt PC)
Lenovo H520S desktop PC
Windows 8.1
1tb hard drive
8gb ram
Asus GTX 650 2gb GPU
500w PSU

I recently had a case change on my PC so that I could fit my GPU into it as it would not fit in the original case. My internet before i had a case change were fine at around 20mb/s download. After my case change my speeds dropped to either no connection or maximum 2mb/s download. I was wondering if my case change may have caused any problems? As a result of this, I thought that my signals were low around my part of the house as my phone also was a bit slower than usual so I bought a signal range booster/extender off amazon which made my internet better in the fact that it actually had full bars connection. I was happy with this because I could at least use the internet. However, when I did a speed test, the download was only around 4mb/s. My router is placed at the other end of the house which may be a factor for this but I still should get more as I was getting more before my case change. This led me to believe that my wireless card had some sort of issue with it. I just wanted to check if I was thinking along the right lines as I don't want to buy a new wireless card if that isn't the problem. Are there any other methods that I can try? This wifi issue is quite annoying as I do a lot of gaming and I can barely get a good connection to online games or even skype calls.

Any help would be appreciated as I would like to try as many methods as I can to fix this issue.
This is the wifi card I am in two minds of getting:

Thanks very much :)

    Where is the WiFi antenna located now that you've moved the system over to a new case? If the antenna is now inside of the new case then the case is acting as an RF shield blocking/reducing the WiFi signal from reaching the antenna.

    Hi,

    The antennas were always inside the case. The wireless card isn't so much a 'card' but more of a processor looking component on the actual motherboard. The new case has one antenna inside the case and the other one wiring out of the case onto one of the screws of the expansion slots on the back of the case. Do you know which type of wifi card I'm talking about? It literally does look like a processor placed on the motherboard with two wires coming out from the top which are the antennas.

    Thanks,
  3. I'd get an external wifi card, it looks like the case is blocking your signal.

    Hi,

    Yes since then i have bought a wifi card (the one i left a link if) and it works great. Back up to my normal speeds and loving my pc again. Thanks all for suggestions :)
  5. That black plastic antenna box on the Lenovo H520S needs to be located on the outside of the case. I don't know if the antenna wire was long enough to allow you to connect it in your new computer case. If it wasn't long enough and the black antenna box was located inside of the new computer case then that is a problem.
