Hello all, first time poster long time lurker lol. I have a sprint note 4 and I've tried 6 custom roms tonight all seem to have slow wifi connections , the signal is strong it does not drop but just slow and not as quick as it used to be prior to flashing a custom rom. i've searched and searched but still can't find any resolution. i have great LTE speeds but when i'm at a location that has no sprint service or low service area i don't want to have to be stuck on network data because the wifi is slow. any insight would be great thanks in advance.
