So I just got a Linksys AE2500 wireless adapter, and when I first plug it in, it is at a solid 5 bars. (I got this new one because my old one kept disconnecting). However, after 20 seconds or so it drops down to 1 bar. my old adapter (TP-Link WN722N) stayed at a constant 4-ish bars. Does anyone know how to fix this?
