I have several devices that use the B rail of the 80211 WiFi signal. Apparently around the 16th of March Xfinity rolled out a network change that removed the B rail from their gateway routers leaving only the G and N. Now my devices no longer work. I spent considerable time attempting to get into the WiFi settings so I could follow the Fitbit advice on how to restore the B rail and was able to do it. My Fitbit Aria worked great for one day. The next day it would no longer connect to the network as it appears that Xfinity pushed out another "update" to their network. I spent an hour today trying to replicate the way I was able to get into the router to modify the settings again but can't even find where to make the changes. The only access to edit I can find now is to change the Name and the passwords. Many other Fitbit customers have the same problem so it would be nice if Xfinity could put up some suggestions on how to ensure the B rail stays on the 2.4 GHz rail.
Would appreciate any help the community can provide.
Solved! Go to Solution.
This thread is a bit old, but I suspect that the issue isnt the "B rail " (whatever that means) but some kind of conflict with the 2.4Ghz band; I'd suggest changing the 2.4 Ghz channel from Auto to either 1,6, or 11.
There is a long, long thread on the Fitbit support forums about this. Some of the advice given there (by Fitbit!) is good, some is bogus. Here's what I've found out and worked out in the past week.
Great, glad that helped! I have to say, though, that after a few days my scale disconnected again, and it seems to disconnect every time there is the slightest hiccup on my WiFi network. Very frustrating.
If you do this will you lose connection to other devices (cameras, printers, etc.)?
That I don't know. I haven't experienced any such problems. E.g., I am able to print from my Android phone over this network. I think (but do not know for sure) that this process simply allows 802.11b devices to connect, alongside more up-to-date 802.11g and 802.11n.
