Hi, I'm new here.
I recently started building a mining rig. I live in an apartment with a couple other people and it's not feasible to connect the miner to the router with an ethernet cable. I bought a usb wifi adapter (

At first I mined with 1 card, while waiting for the risers, and that worked fine. but when I added in more cards, suddenly my connection became very unstable.
I'm using the H81 BTC pro motherboard from Asrock. At first I did not have a molex connector plugged into the motherboard and I thought it could be a power issue. Plugging in the molex connector didn't make much of a difference.
I tried plugging the wifi adapter into different ports. It definitely worked better when plugged into the usb 2.0 port. At first this seemed to be the problem and it worked for about 1 hour. After 1 hour, the internet connection would just completely shut off and I would need to restart the computer or unplug/plug the usb adapter.
I then bought a different usb adapter (

It runs for a few hours at least, and it has been running all night and it's still up. However, I'm getting a lot of stale shares. The time, in ms, between finding and accepting shares is usually in the thousands and sometimes as high as 20 or 30,000. I usually mine on nanopool and that doesn't show me stale shares, but I ran it on ethermine.org for a while and the stales shares are about 10%.
I'm not sure where to go from here. Right now there are only 3 cards hooked up and I'm worried that trying to hook up more cards will just make the problem worse.
I would like to try another adapter that has an antenna, but I'm not certain that would make a difference.
Any advice would be appreciated.
