I have Motorola XT701 (Milestone,Motoroi or whatever) and I flashed a sbf and the wifi has very good signal but I don't have the android market. If I try to root and install a much better rom with market the wifi signal is very weak. I tried to open the sbf and the CG39.smg (system image) and replaced the app folder in there but when I compile the new sbf I can't flashed because the RSD is giving checksum errors! I had installed even CM7 wich is great at speed and market is present but the wifi has very weak signal. In all roms I had this problem maybe because most of them are for the milestone A853 or A953 or whatever? Should I edit a specific CGxx.smg? The wifi signal is the only problem I have after I root, but I like the phone very much!
