I got my Vibrant yesterday and hooked it up to my wifi (netgear g-router). Everything worked great... for about 30 seconds. I was able to jump through a few pages and then it stops loading... eventually i get a message with something to the effect of "cannot connect to server, please try again later".. this is not word for word. I called t-mo support and they were not able to find anything so they are sending me a new Vibrant, but I have a feeling that this problem will persist.. I read through different posts and found a few that listed this problem... some suggested: -Download the WiFi Fixer app from the android market -Switch the router settings from B/G to just G (I dont remember what mine are set to now, but i'll try this out when I get home from work).. If I really have to switch my router settings, what will I do if I'm travelling and have to use a hotel's wifi hotspot or something?? Does anyone have any ideas about this?? I have no problems with my wifi on my MyTouch 3G... so I'm not sure if this is a Samsung issue or an Android issue... either way, I either have to figure out a fix or get rid of the phone. Please help if you can! any suggestion is appreciated! Thanks in advance.
