Recently I've started encountering a weird bug in my Windows 7 x64. I have an Asus N53SV with an Intel Centrino Wireless-N 1000. When I physically move the laptop, eg. move it to another room or just nudge it a little bit when it is sitting on my lap, it loses signal. I still see 5 signal bars on my taskbar, but I lose Internet connection and when I click the icon in my taskbar, I only see the hotspot I'm currently connected too (normally I see ~24 hotspots around my house). Soon after, an orange triangle with an exclamation mark shows up on the icon saying that I have limited connection.
To temporarily fix the issue, I need to disable and then enable the wireless adapter again, or reboot the laptop. As you can imagine, it can get very annoying very fast. I've been using a USB wi-fi since to be able to normally work. However, before sending it to RMA, I decided to boot up one of my old Linux live CDs (Linux Mint 10) to see if it acts weird, too (then I could say for sure it's a hardware fault). The thing is, it doesn't! I literally can't make it lose connection now.
I hadn't changed any drivers in my laptop and when it started doing that, I uninstalled my wi-fi drivers and installed older ones. What do you guys think about the issue? Have you ever encountered something like that? Any ideas what could fix it except for reinstalling the OS? Thanks!
WiFi is radio waves, and those are shielded by metal (i.e., in building walls) and to a lesser degree by other materials. Reflections and other phenomena can interfere with the reception. Besides, the WiFi range is increasingly crowded, if a nearby WiFi access point is using the same channel you are using, mowing around cn make that one mask the signal of yours. – vonbrand – 2014-07-27T18:31:33.323
No other PCs in my house are having this problem. Also, I don't believe there would be any kind of shielding that would shield wi-fi signal from all 24 hotspots at once by just touching the laptop. – Filip Vondrášek – 2014-07-27T19:18:51.417
Sensitivity varies quite a bit between machines – vonbrand – 2014-07-27T23:07:27.417
But this one was working perfectly fine for 2 years. :( – Filip Vondrášek – 2014-07-28T09:28:57.310
