After switching to XB8 xfinity gateway ,my TV's internet connection keeps dropping several times a day , i see my wifi gets disconnected . 

Earlier i was using my own equipment and never had this issue.

Any idea why XB8 wifi connection keeps dropping for my TV. Very horrible experience and degrade in internet issues.

I read some xfinity forums and tried many things like disable advance security , changing the wifi name to keep it seperate for 2.4ghz ,5ghz and 6 ghz.

When i called customer care it worked fine then but once we got off the call again i am experience the issue.

So its hard to re-produce the issue when support is taking a look as it occurs randomly , it has been 1st day of usage and i saw my tv wifi connection getting disconnected every 10 mins (i then had to again connect my tv to it) and then every 20-30 mins and now it happens randomly every hour or so.
