Our modem is an Arris TG862. We have 3 laptops currently hooked up by wifi and we have 3 iPhones that were able to join the network 2 weeks ago but no longer have access. The iPhones are on different accounts through AT&T. I've tried forgetting the network on my iPhone and resetting the network on my iPhone and still cannot connect here at home. We can connect to WiFi hotspots or at friends' homes. The connection wasn't that great to begin with here. Comcast and this Modem have to be the reason we are having problems! Any help is appreciated! Thanks!
Even iam facing similar issue I've 1 iPhone & Android -Samsung Blaze both connects for some time but later not able to join the network..
I've restarted modem multiple times and later once i changed DHCP range and it worked properly for 10 days but again .. same problem... tried static IP, restarting mobile, reset mobile to default factory settings
Both mobiles works well on other wifi/s but doesn't work at home with Comcast wifi-router.
I'm also having this problem and running out of data on my cell phone plan. Sometimes I get error messages saying "Unable to connect to network '-----'." Then sometimes it will show I'm connected after trying several times except when I try to open a webpage it never loads then I get the page saying that the server stopped responding. I have an iphone 5 running operating system 6.0.2. Hope you can help!
Thanks for the effort but I tried what you suggested and it didn't fix the issue. The little icon at the top said it was connected but no webpage would open. Or for one second Google would load and then I tried to refresh to test it and it was back out again. This is so frustrating!
I just came onto the forum to post the exact same problem. We have 4 iphones and 3 of them can connect to our home network fine but my son's phone can't. I'm getting killed with data charges since every time he uses it it's using data. I thought it was a problem with his phone so went to AT&T but the phone was able to connect to their network without any issues.
They suggested that maybe I had an older model modem and that I had too many devices pulling from it. Right now we have 3 laptops, the other 3 phones, a wireless printer and a tablet. I was going to check with my local Comcast office to see if that could possibly be the issue. Does this seem like a plausible reason?
I had the same issue with my new IPhone5 But FINALLY FIXED IT! First you need to ensure you are running the latest update (6.0.2) bc it was made to help resolve these wifi issues.
If you are already current on your update then please make sure you reset all network connections by going to general settings- network- reset. *If you are just completing your update then you do not have to do this
Last step: Most important: Renew your lease when you the log in password for your SSID is accepted. At that time it should work. Mine did! Im still happy about it!
Bruce, if I go back to using my own wireless router will that affect my internet speed? We had used this wireless router before "upgrading" to this new Comcast one with the phone service and we had all kinds of connectivity issues. Comcast told us that it was just the old modem we had that was causing the problems but right now I trust them about as far as I could throw them, I just would like to make sure that if we go back to the same router we won't go back to the same problems.

Without additional information (especially the model number of the router you want to try, and the current modem signal levels) it's impossible to say. And really, the only way to see for sure how a new equipment configuration performs is to try it.
Personally, even if the previous router was a bit slower, I would trade a reliable connection for a slightly faster but unreliable connection just about any day of the week.
Thank you, Audrea24 for posting this info! I just had Comcast set up my wireless network and was so frustrated that everything, but the iPhones and iPads were joining. I saw your response, followed it and WooHoo they all joined. You saved me a lot of frustration!
A week ago, all of a sudden, our iOS devices dropped off the network. They would come back on together and then drop off together. Xfinity help line did a reset on the modem, which helped for a few hours, then same problem came back. Microsoft devices were fine. A follow-up call elicited an offer to sign-up for monthly support program, with them waiving the $40 set-up fee, but a $15 charge. We refused offer and asked for another reset. Another call elicited the suggestion to buy an airport device for the spare router port.
We were close to calling AT&T to come back when I decided to search the Internet for like problems, and found a suggestion in this forum to go into the Comcast gateway management and disable the parental restrictions. I did that and then set up our iPhone and iPad devices as trusted. It has been a couple of hours since I did that and all seems to be well now. Hallelujah!
Xfinity technical support was useless. If this is a known problem by the forum, they should be figuring it out and advising customers to do that.
When we first installed the system a few months ago, we had major problems with getting my office VPN phone to work, had 2 different technical support people tell me they did not support VoIP, which was ridiculous, and ultimately figured out their routing scheme (10.xx.xx.1) was in conflict with our corporate standard. Changing the IP addresses of the gateway took care of that problem, just in case you ever run into that one as well.
I had comcast install the bundle a few days ago, and immediately couldn't connect my iphone 5 psp3 but could connect my sony laptop and had a weak signal on my ipad 2. I called comcast repeatedly and finally decided to ask them to bypass the built-in router on their device as I had my own router. They did I connected my router to their modem and have connected all my devices and the speed is much more like the blast I'm paying for. Good luck I hope this helps.
I'm having the same issue daily. It will stay on network all day then ill goto work and come home....unable to join network. Currently i have all the devices connecting to the gateway via WIFI set up for ALLOW on mac filtering. We shall see. However to let everyone know. The ONLY way i have been able to reconnect my iphone 4 is to log into the customer side GUI and make a minor change. Any change has worked. Including removing a disconnected device from the connections list. So stupid. The GUI does not always show whats REALLY connected. And it bounces non stop. Terrible, TERRIBLE interface.
All our Apple products stopped connecting to the wifi yesterday while all non-Apple products were able to continus connecting. Thanks to this thread was able to find the problem was due to Comcast and nothing to do with our ipad/iPhone/iPod... Went into the Xfinity Gateway (first time logging in here - we've been on Comcast for just 2-3 months now) and disabled parental controls, but it still did not work. Then went and manually added each of our devices and now they are all back to working on wifi !
This worked for me, too, after a couple of months of frustration. I have an iPhone 5c and ios 7.0.4 but still had the same trouble connecting. I did the general settings-reset network and reloaded my password and it worked. A three-minute solution. Thank you, audrea24.
My wife's iPhone 4 wouldn't connect to our new Xfinity X1 data / voice / modem / router. After reading your posting, I reset the network settings, re-entered the password for the router, and it connected!
just chiming in here and was reading up on the topic, in mycase it's an Ipad which only connects for a certain time. However could somebody give me the exact steps again for possible solutions. Since I pad is an apple device it is pretty much the same problem.
