A little background information:
I recently moved to a new home, initially I connect my desktop with a USB wireless drive to the router. I was able to get spotty internet connection and browse, but no games would work, I'd always get a failed to connect to server message, or something along those lines. I was getting about 3 bars of wireless signal.
Next, I moved the router into the same room as my computer, this allowed me to get full wireless signal and browse the web quickly and freely. However, I was having the same issue when trying to play any PC games online. Issues connecting to servers, errors loading pages.
Finally, I connected my PC to the router via ethernet. This gave me fast internet browsing, quick loading of all youtube videos even in HD. A speed test shows a ping of 12ms, Download speed of 21 mbps and an upload speed of 2.19 mbps. However, similar circumstances. Lets take League of Legends for example, I get an Error: Unable to lead page message in the client when trying to display the main page of the client. In other games a typical message will be unable to connect to server or failed to connect to lobby.
Does anyone have any suggestions as to what may be the issue here? In my prior home, I had very similar speed test results, and actually moved to a more populated area near a city, so I don't think I moved farther away from any internet hosting. In the prior residence I was able to game with great connection and minimal latency if any, here, I cannot even connect to a game to begin to see what my latency would even be like.
Internet provider is Time Warner Cable both in prior residence and here.
Any help or suggestions would be greatly appreciated.
Does the router have an extra low voltage transformer?
If it does you should check that out first, as on cheap routers they are done in around the 10 months mark. Typical symptoms are good ping speeds but problems as soon as you use any bandwidth.
