I have a cheap WiFi USB receiver connected via a USB Extender. I get good strength but poor link speed specially when the device gets hot. Like sometimes hot to touch. The link speed drops dramatically when the device is heated but as soon as I touch it, the link speed gets back to normal and better (to an extent).
ADDED LATER For both the tests, I am buffering a YouTube video at 480p.
PS: It was quiet warm.
Now the question is why does this happen?
I have a few theories:
- My Skin's capacitance increases the WiFi range by acting as an antenna
- My (or anyone's for that matter) body is 70% water, which means it absorbs microwaves effectively, that could help the device gain signal/link strength.
- I act as a heat sink for the USB device which helps it to regain its effective working (my bets are on this).
So why does this happen, is it any of the reasons I have mentioned or something different.
PS: My tags are aweful, if a mod/anyone want to change/correct them you are more than welcome.
I just noticed something. Tighter my grip, better the link speed. So I guess it has to do with something that increases with surface area.
