intermittent wifi

My modem is an arris tg862g/ct and does not have a battery in the bottom. Since my service went to blast it has been hit and miss with being able to conect thru wifi. Comcast has done something on their end to try and take care of it. I have reset my modem which took care of the problem for a short time. When the wifi light is steady no connection when blinking it seems to work. Most of the time it slow for all my devices.

Can anyone offer some suggestions in not so techie language? I am not sure if I need to replace the modem or do something else. Modem also serves as router.

Thank you for any and all support.

I'm having the exact same problem, just recently upgraded to Blast! and now having intermittent WiFi and when WiFi does work, DL speed is 0.54 Mbps and UL is 12.5 Mbps average..............really? If I'm connect through ethernet, speeds are fine and connection is fine. 

 

Update: Just got off Online Chat and here's what the Rep did:

 

Jose Raphael : I will change some setting on my end

Jose Raphael : We may get disconnected for a minute or two

Jose Raphael : Please do not close this chat session

Jose Raphael : Thank you.

Jose Raphael : Your gateway's bridge mode is not set to enabled or disabled.

Jose Raphael : I changed it to disabled.

Me: okay?

Jose Raphael : I also enabled your wireless connection which is not enabled on our end.

 

Once he made those changes, I'm not having issues with WiFi.....................(fingers crossed).

Re: intermittent wifi

My wifi does not reach where it should;  iPhone can't connect, smart TV connection is very spotty.  What info can I send you so it can be fixed?  I have an Arris TG862G/CT since Feb 2013.

Re: intermittent wifi

Same issue as the others in this forum. Wifi has worked fine for a year with 28 UL and 5 DL speeds. Suddenly (overnight) my wifi speeds are all over the board. I have the same Arris tg862g/ct gateway. If I use an ethernet cable, speed is normal 28/5. Wifi is 0-10 UL and 0-5 DL jumping everytime I test it. Xfinity has sent refresh signals, changed channels, sent out a technician, all say everything is fine. All I know is that for a year my wifi speed was 28/5, now it is not good enought to watch a YouTube video.

Re: intermittent wifi

Hi,

 

there are big problems in the past 1-2 month, just look in the forum.

In my opinoin, It is a result of a software upgrade to the router tg862 see here.

Instead of wasting your time blaming people for their wrong configuration/ hardware problems can someone please take responsibility and tell Arris to fix it or to rollback the upgrade?

Why not saving thousands of calls/ chats/ field people visits in one move?

 

Please reply with updates

I don't know how to pm, but I just recently started having interment connection and low speed issues when I can connect. Comcast says I have the newest modem. I tried several troubleshooting things with tech on the phone. When that didn't get me anywhere I went to a service center and replaced the modem with another one. Now after activation it seems I'm still having the same problem. speedtest.net averages around 1.5 Mbps down and 2 Mbps up while on wifi. Connected to an Ethernet cable it soars to 52-55 Mbps down and 10-11 Mbps up. As most of my devices are connected via wifi this is a game changer for me. Please help me correct this issue so I can continue using comcast.

Re: intermittent wifi

Hello Everyone,

 

Was this issue ever resolved? I'm having the exact same problem. The DL speed on Wi-Fi remains between 0-5 Mbps and UL speed is constant at 10-11 Mbps. However on the Ethernet, the DL speed is 55-56 Mbps and UL speed is 10-11 Mbps.

 

Already technicians have visited 2-3 times but to no avail. The customer service guys just ask me to reset the modem and do something on their end which isn't helpful at all. Its becoming really frustrating now.

Re: intermittent wifi

I guess I'll add my voice to the conversation.  I have been having the same issues with the Arris TG862.  Intermittent WiFi connectivity.  I have reset it, the customer service has reset it, signals have been sent and my last conversation was yesterday.  Is the problem with the router?  Can Comcast just offer a more stable system?

Re: intermittent wifi

I am having the same problem with the Arris TG862.  As a result, my family is blowing through our data limit with Verizon and this is costing me real money.  I have reset the modem, but wifi connectivity is spotty.  My Samsung tablet seems to connect ok, but my phone (Samsung) drops wifi every time I leave the house and will not rejoin automatically when I return.  My wife and kids all have iPhones and iPads and cannot connect, and neither can I connect my IBM/Lenovo or Toshiba laptops.  I need an answer ASAP.

Re: intermittent wifi

I have been having similar issues with dropped WiFi signals since December 2013. All of a sudden we began having dropped internet connection, even though the signal from the wireless router remains strong. The problem is more pronounced the farther we are from the router, but will occur even if we are within line of sight of the router. We had an older DLink router, which was upgraded to a new Linksys router. We changed the cable modem with Comcast, but have not tried the Comcast router as we were not given the connection information. We have changed the router channel to 11 and I downloaded a program that searched for nearby signals and none of my neighbors are on the same channel. I even changed the surge protector on the advice of a network engineer. None of these things have worked. We get dropouts about every 5  minutes, lasting for about 5 minutes. I am unable to reliably connect to my work VPN or watch a show on our smart TV without getting dropped. 

 

I see a lot of people asking for help on this forum and no answers. Has anyone been able to resolve their similar issues?

Me too! Unbelievably frustrating. No solution yet, other than finding another provider. Comcast / Xfinity reps? Solution? Bueller?

Re: intermittent wifi

Depending on your residential building type and the materials used to build it, you may need to invest in a home network extender....   if you have an ARRIS modem, they are horifically bad even 40 feet down a hallway...   I instaleld a Cisco Network Extender and have no problems now... in fact, I installed 3 of them throughout my residence!!!   All with the same names, so my devices automatically connect to the highest signal regardless of where I walk throuout the house....

Re: intermittent wifi

Hi.  I'm having intermittant problems as well.  I just switched from a Technicolor modem to the Arris TG862 (both Comcast provided).  I hesitate to do a restart because I have an Airport Extreme as my router and so my modem needs to be put in Bridge Mode by CC.  This always means a couple of hours on the phone.  Should I ask for, and would Comcast provide just a telephony modem that would never have to be put into bridge mode?

Re: intermittent wifi

Extremely easy.... in fact,. you press the top button on your ARRIS, it begins to blink, then you goto the Cisco Extenders and press the same button on them...  they AUTO-CONNECT to your ARRIS and add _EXT to the end of your Arris's name  ( example:  your arris is HOME-8934   you would then have a CIsco Extender named Home-8934_EXT.

Re: intermittent wifi

I also have a wifi problem with the xfinity ARRIS TG682 modem.  The ethernet and telephone work just fine, no problems there however the wifi is intermittent especially in the late afternoon and evenings.  Now my modem's wifi light flashes rapidly and I could go several hours and the wifi is fine and then it slows down to a trickle and eventually shuts down although my computer shows wifi is working and accessing the Internet.  I don't have "Blast" and I am not sure what that is.  I did call support and they did something at their end that improve things until that evening and we were back to intermitten wifi again.  I am open to suggestions.  I thought it was our computers until we accessed other networks

Re: intermittent wifi

Maybe its me but I think Comcast should consider another vender for modem/routers.

Not just you, the Arris works fine as a modem and eMTA for voice, but is lacking as a wireless router. Internal antennae and poor signal strength make it a less than optimal choice.

Options are to have Comcast support place it in Full Bridge Mode (no router, no wireless), then obtain a wireless router of your choice.

If you do not need the voice option of eMTA could replace modem entirely with a decent supported DOCSIS3 unit from supported list to save on rental.

What router to get depends on your need/usage. No point buying the latest greatest AC2700, or dual band N900 if all you have is older laptops and tablets on wireless. Just make sure it is gigabit on Ethernet side for fattest pipe and dual band 300/600 would give a little more capability for not much cost.

Splitting the router off from modem gives better control and means you can upgrade or replace only what is needed.

I am not sure what "bridge mode" means, is it something I can do myself?

Bridge mode means that the gateway is in effect turned into a simple modem, you will still have eMTA support for voice, but router and wireless are turned off.

 

You cannot set this mode, it has to be done from Comcasts side. Request it in a live chat if needed.

I also have intermittent problems.  In about July they began.  I called Comcast for assistance, and the tech walked me through a reset.  I had to do it manually because they couldn't access the system from their end.  The problems persisted, and on the 21st of August it got  worse.  Another call to tech and was advised to trade in the modem/wireless.  It had the same problem.  Another trade in and again the same problem.  I have quizzed my neighbors, and most report intermittent service.  Two have switched to Century Link for service.  Is Comcast addressing this problem?  A service rep is due this morning.  What do I say to them?

The service rep came and when I said that multiple people on my street had similar problems, he said that he had checked the signal in the area and that it was ok.  Each person has individual problems.  He changed the cable ends and checked the signal.  He said that the signal was strong and since I had just changed the device he didn't need to change it again.  I will wait and see.
