My wifes gateway laptop wifi about 40 ft away gets 60mbs, ps4 gets 23 mbs wifi right next to it and the ps3 about 15 ft away gets 14 mbs.
I formatted my laptop again and put windows 7 on it cause i thought maybe that would work and it did last night and this morning but now its back to doing low download speed and high upload.
I have toshiba satalite l875d-s7232 laptop and the wifi adapter is wnda3100.
