Posting in this general forum as there's no forum for my specific (Canadian) Samsung Galaxy 550 phone. I only connect on Wifi @ home with great difficulty & lots of fiddling around while elsewhere at internet cafes etc. it's all fine. I'm in an apartment & Wifi Analyzer often tells me there are a lot of wifi signals reaching the phone, sometimes crowding my channel. I'm set for the optimum channel avail. I never had difficulties connecting to my home wifi on a different device, just this Samsung phone. I have no data plan & wifi's my only connection so the lack of reliable connection @ home is a big pain. PS from time to time my home PC has given msgs about conflict there being an IP address conflict from another device, but that's only once in a while. I've tried stopping network connection on the PC, turning off my home entertainment unit, radio & any other devices I can control, usually to no avail. The wifi connects succesfully sometimes but keeps losing it and with certain more sensitive apps I just can't download things.
