Home Internet Overheating

I have had T-Mobile home internet for about week.  I experienced a total loss of signal to all connected devices several times a day once the unit heated up.  This started on the very first day.  I googled the issued and even though there are skeptics about the heat issue.  I bought two 120mm fans one to blow air up from the bottom and one to set on top to pull air through.  This keeps my unit cool and I have not lost internet to any of my devices since.  It has been four days now and still going strong.  This appears to have solved my problem.  Good luck for everyone else.  I just though I would share.

I recently got T-Mobile Home Internet Wi-Fi. It has been two days, and I've noticed that many times my internet just drops/lags for few seconds but it suddenly comes back. I sometimes use it for gaming, however it is really annoying that sometimes there is random lag spikes or even drops that make lose connections during games. I've been doing some research to find a solution, but the closest thing to my issue is what other similar people have. I'm not sure if I try setting up some fans with the modem could solve my problem. Which it might be an overheating issue, which I'm assuming. 

I set my T-Mobile home internet gateway on top of a fan with a temperature sensor.  This seem to largely resolve the stability issues.

Merry x-mas all.. I 3d printed a 2 piece unit to allow mounting a 120mm fan to the base of the hotspot.

base has a finger guard to protect…. your fingers… 

coupler allows the hotspot to sit in a 120mm ‘cup’

between the unit, sandwich your 120mm fan and link all together with 4 wood screws (length depends on the thickness of your fan.

place fan with blow direction ‘up’

Looks like I'm getting the overheating error WAN005 and another one WAN002. Everyone here fixed the issue with a fan it would appear but I'm confused about my issue. My unit doesn't feel hot or last more than a 20 or 30 minutes before it kicks off line with an error. I have to remove power and that resolves the error only to have it happen again a few minutes later. I have the new 5g model also, not sure if anyone is still seeing this issue?

Overheating problem solved. 2 weeks and no more drops.  (TMobile, please do something about your hardware, though.)

I understand. Many have commented on it and I haven't read them all. I was just thanking you for bringing my own attention to it and for posting a particularly cogent description. ¡Saludos!

@Unknown420: All electronic devices produce heat. When engineers design products, part of the process is to do a "thermal analysis" and then testing to ensure that the heat doesn't build up inside the enclosure, creating a safety hazard, or allow a device (think chip) to get hot enough to malfunction and quit working or perform marginally. To port the heat away, the mechanical packaging can employ active measures like the fans in your computer, or passively using convection of air through the housing as is the case with the T-Mobile gateway. Having said that, there's the always the possibility of a component failure causing dangerously high temperatures inside the enclosure (as in fire). So when you say "extremely hot", don't discount this possibility and err on the safe side by exchanging the gateway for a different one.

By way of an update, I've been running my gateway for over a month, mounted atop a muffin fan forcing room temperature air in through the base of the unit without seeing the original problem of periodic decline in data throughput. Others here have reported similar experiences, though the failure mode isn't always the same. I've reported to T-Mobile my suspicion that some engineer didn't do his/her homework (adequate environmental testing) before this product was released for production. So far I've heard nothing back. Such a shame, and so short sighted of them. I know they have people monitoring this forum.

Wow! so many users complaining about the same/similar issue.

Mine loses internet connection everyday ~8:30 PM ET.
Sometime it is restored on its own and sometimes I have to reboot the device.

I have a WiFi mesh system(not WiFi 6) on top of this gateway and intially thought that was the culprit but looks like not since I have had the same issue directly using the gateway’s WiFi

I hardly see any response from T-Mobile in this forum for so many issue reports.

With WFH going to be new norm for sometime, I am thinking...was it a wise decision to move to a cell phone connectivity based internet?🤔

It looked wise from a technical standpoint atleast when I took the decision.

Just adding in the same problems many have had. High traffic led to a hot Internet device led to internet drops and massive speed dumps (180mbps to 5mbps). I got the usb fans yesterday and my speeds have remained around 150+ speed all day. all this leaves me to wonder why on earth they produced a device with insufficient venting and no fans to begin with?
