Android phone not connecting to home wifi
This isn't a question. Instead it is an answer, for anyone who may be having the same issue.
In early February, 2022, two of my Android phones stopped seeing my home wifi network. They saw and connected to other networks, but my own was invisible to them. Two laptops and an iPhone both continued to connect without issue. I spoke for an hour or so with a chat agent, and we tried every trouble-shooting technique in the books (restart this, restart that, factory reset this, factory reset that) and nothing worked. I scoured the internet for a solution, including this forum, and found none. A couple of weeks later, I was contacted by an Xfinity sales representative trying to sale mobile services. I picked this poor representative's brain about my wifi issue, and he mentioned that some older phones have trouble with 5Ghz, and that Xfinity/Comcast switched to 5Ghz exclusively (but, if I buy a new phone and mobile service I'll be fine). Sorry, I wasn't interested in a new service, and thought it suspect that Xfinity was unable to solve my wifi problem, yet expected me to buy other services.
Now that I was aware of this 5Ghz issue (which I was completely ignorant to before), I began to search more, and found a thread on this forum which suggested splitting the 2.5Ghz and 5Ghz signals. I tried this, and my phones still did not see the network. I continued to search, and found a video on the internet, in which a person suggested acquiring a new modem to fix wifi signal problems. I went to the Xfinity website, and lo... it turns out that anyone with an old modem can simply request a replacement, which I did.
I received my new modem in the mail, split the two signals on my account, and like magic, my phones can connect again (to the weaker 2.5Ghz signal, with my laptops on the 5Ghz). I returned my old modem with no problems.
To Xfinity/Comcast, can you please train your technicians in this issue, so that no one else with a moderately old phone (of just a few years), doesn't have to spend a month troubleshooting their wifi connection. In my case, I receive poor cell phone reception due to new construction in my neighborhood, and I often rely on my wifi connection for phone calls while at home, making it a very critical service to unexpectedly loose.
These are two other threads attempting to solve what seems to be the same issue. I hope this helps someone.
Sincerely,
An Xfinity Customer

After doing all that you did with and without a tech on the phone I was advised to visit my Xfinity store with no success as I knew our two phones would connect there. Out of desperation tech is coming to the house Monday. I will tell and show that phones won't connect but tablet will and friend's phone will. We cannot even connect to xfinity wifi at home so we are totally dead in the water. I am NOT going to be coerced into buying new phones JUST because they say its the only way to solve this unless they want to pay for them. NOT everyone buys new phones every couple of years and we have zero need to do so. Our phones are 4 yrs old and serve us well and Xfinity going 5G should not blow up our world. We are also losing phone network connectivity regularly. Have to restart phone several times to get bars back and then we only get 2-3! And I had to turn on data to update my apps the other day and in less than 15 minutes it used half my allotted 1G of data. WHAAAT? We only turn data on if we have to and that is RARE so I was really upset. .5G to update 30 apps...are you kidding me? As you know there are many reported cases on these forums of the same issue you and I have. If they want to swap out the modem Monday they have my blessing. It is the latest version of the 1G gateway so who knows. I am going to print and show the tech your posting.

The most wonderful Comcast tech visited me today to diagnose the issue of our cell phones not connecting to home wifi but tablet will and other people's phones will. After checking/changing/removing/resetting stuff in phones with no success he was pretty sure it was the phones themselves and wanted to try resetting to factory settings but I refused....no thank you. I was resigning myself to having to get new phones. Then he decided to do all he could to make sure everything we have is up to date and went to the Comcast connection to the house and upgraded it....said it was old stuff and was probably causing the 'having problem connecting to the internet RDK 030333' error we have been getting on the tv too often. Then he worked on the splitter inside the house.
He had already added a 'new' home wifi with new password and that didn't work so he cloned his cell phone wifi setting on my phone to see I could connect but nope. Then he decided what the heck and swapped out the modem and set the home wifi setting back the way it was and VOILA....CONNECTED to home wifi and xfinity wifi. Added benefit off all he did was that we are now getting double the download speed we had before. Soooo.....looks like three birds were killed with one stone. I am one very happy Comcast customer this afternoon. Still don't 'get' why tablet and other phones would connect before and ours wouldn't but not going to dive deeper into that. I hope those who have also had this issue with phones that are a few years old get their issue resolved.
