Home Internet Overheating

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’m going to try putting my gateway on top of this:

Have not had resets, but noticed gw gets very warm, so suggestion of case fan sounded good. Then noticed my air purifier from Costco which is very quiet. Built a stand out of coroplast (yard sign) since it is slanted at the vent with a hole to push the air through the gw. If turn off purifier for half hour, gw gets very warm again. Using wi-fi in gw router since better than my old one. The passive cooling just is not enough for many cases. I have a case fan from a PC build and know how noisy it can be, so the air purifier is quieter. See what you got. Ikea and other stores have something similar. 

     The purifier is 20 inches tall so the gw is higher which is better for the signal. I am pretty lucky living in a college town with good towers so get two to three bars of b66 and n41. Speed varies between 40 and 340 but usually over 150, often 270. Netflix runs smooth even with other streaming devices going. Usually have less than 20 wi-fi devices connected.

     Now I can cancel Cox Cable which is raising the price again. Due to price last year had to downgrade Cox plan to 50 mbs and was only getting 35 to 40. I feel lucky that I now have a choice! Hope my shift to T-Mobile will support development and deployment of Home Internet to rural areas where there is not much choice. 

     The app and the web gui for gw could use some work, but it is still early days. Would like to have more detail of the connected devices of wi-fi and more settings. But understand need to keep things easy to setup. The guys at the local store were very helpful getting my Sprint migration done and Home internet ordered over phone.

There *is* at least one temperature sensor and that’d definitely be great to add to the status on the mobile app and web UI for the device.

The manual has alerts for “HighCPU Temperature” and “ModemHighCPU Temperature”

I don’t see a way to actually see the alerts other than scrolling through the tiny screen options on top of the router so that’s not ideal but might show if the temps were actually ‘high’ according to whatever definition is used.

@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.

I have my home internet and it gets extremely hot why is that

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!

@Farjohn I just replied to your other thread and referenced my own before noticing you had posted here first.  :)  I don't want to take credit for discovering the heat issue.  Someone else mentioned it on another thread and referenced a thread on Reddit which is where I first saw the suggestion.

@jlillard I’ve created a new discussion on the heating issue you steered me to at

I Thought I'd post it under your thread as others might look here. Thank you for first tipping us off on the thermal connection.

@jlillard, I didn't phrase that well and see no edit function here. Rather than pushing the hardware at higher speeds being a "symptom" of a heat issue, what I meant to say was that if the gateway performs better/longer when you offload some function like wi-fi routing or slow down the data transfer speed, this can be indicative of a heat problem with the hardware.
