I have had the Roku Express for almost a year. It automatically would connect to my home network and work just fine Up until a month ago. It just stopped connecting to it. Itll connect to my tmobile hotspot on my phone just fine when i turn the hotspot on but refuses to connect to my home wifi/internet with xfinity all of a sudden. i have restarted & unplugged both my modem and my roku.
Thanks for the post regarding internet connectivity issues with your Express device.
If your internet service provider is Comcast, we would recommend changing your router settings for 2.4 GHz band from g/n to b/g/n, as customers have stated that this helped resolve their issue.
Please keep us posted what you find out.
@Jdw15 The Express needs 2.4GHz. Xfinity did that to my parents too. They don't have a Roku but they called me over because their Wi-Fi printer stopped working. Xfinity had updated their router and turned the 2.4GHz off so I logged into it and turned it back on.
My parent's router is at 10.0.0.1. I think that is very common with the Xfinity-leased routers. Other common addresses for Xfinity routers are 192.168.1.1 and 192.168.100.1
If you own your own router, the address might be different.
Everyone: if your router is leased from Comcast (as mine is) you don't have the ability to change the mode to B/G/N. You have to contact Comcast support and request them to make the change. They are being all "big brother" about many of the settings in the modem, so you're locked out of those particular settings. Same with channel number, bandwidth, and security mode. Any changes must be done by Comcast.
