So coming from the Hero I was hoping this would no longer be an issue but it seems that Samsung and HTC are using a similar stack for their radios as I have been having Wifi issues here on the moment as well. Just wanted to see if anyone else has the same problems: With wifi enabled, I can browse fine, applications that use the net are working also EXCEPT for the market place. I can search and list apps fine, it just won't download them. It says that it's starting teh download but it never downloads. As soon as I switch off wifi, I get a download/network error, but when I restart the download, it downloads and installs fine. Can anyone try to replicate this? I replicated this about 6 times in a row on my moment - every single time the same result. Then, wifi enabled, the wifi is turned off by itself. over night, during the day, after a while (difficult to replicate as it seems random). If I would have to guess I would say the wifi stack crashes. When I manually turn wifi on again, sometimes my wifi connection comes back, sometimes it won't connect to my network (can see the network, can say CONNECT but it just won't connect). And no, it's not my network as I tried it on a Starbucks wifi and I got the same results.
