On the new grey 5G home internet box, when you connect to its web page (typically http://192.168.12.1/), on the Overview screen, under the Devices panel, one of the items listed is “Mesh Wi-Fi 6 System”, just above “Wireless” and “Ethenet”. This implies a third way of networking devices (it currently says 0 connected). I have a Deco Wi-Fi 6 mesh router and was wondering if they could be interconnected by something other than an ethnet cable. Is this something that is currently implemented or is it just a planned feature for a future expansion?

On their product page (https://www.t-mobile.com/isp/gateway) where it lists device features, it also says “Mesh expandable    Yes”, but I haven’t found any details about this in the documentation.

What does double NAT mean. Does it mean having two WIFI networks? Do they not make wireless nodes that will hookup to the gateway? I see Nokia has a WIFI Beacon 6 but it is not available yet.

So with networking, think of each router as a network (including the T-Mobile home gateway, because it’s also a router). If you link a router behind another router, you’re essentially putting a network behind another network. Each Network has their own address scheme and mapping (NAT), and each need settings on how they communicate between each other and the internet. This brings about different pros and cons.

I’m running a double NAT now, because i have an Asus Mesh (no other mesh is compatible, let alone T-mobile’s “iffy” mesh, not sure about bridge-moding the main router and how it could affect the other nodes). So far, i don’t have any loss of speed/performance, but sometimes my router connection does go down (over dhcp conflicts? my only big issue). IPv6 works fine once i set it through passthrough. In terms of port-forwarding, does the T-mo gateway NOT have a firewall? I get that most of the traffic they block is on their end, but so far nothing is blocked (i only need to forward on my Asus router, and everything goes through). Any tips or advice on settings/config to keep stability/security would be appreciated.

To those if you with the deco mesh systems, what happens when you throw the main puck into bridge/ap mode? Just curious if it hops onto the gateways wifi or not.

I used to have Spectrum (uggg, horrible customer service) & switched to T-Mobile internet & so far love it.  I have Google mesh (older not nest mesh).  I have 4 pucks & connected one to gateway by Ethernet & distributed the rest throughout the house.  I have the gateway behind my tv & live in a house made in the 1920's with lath & plaster walls.  I get great speeds.  I haven't even tried to locate anywhere else because I have such good speed.  The best recorded speeds I have are 493 down & 56 up.  That's with a connection on app that says "very good".  Don't have any idea what I'd get with "excellent" connection..  A whole lot better than I was getting with Spectrum & for a lot less money.  The only problem I've had was speed test dropped in half & called tech support & they rebooted something on their end & I rebooted gateway.  Problem solved.  I will say that I get much better speeds if I reboot gateway weekly.  I'm a pretty heavy internet user, got a whole smart house with a LOT of devices connected & get consistent internet.  Haven't encountered any buffering or stuttering yet.  So far, so good.  Hope it stays that way.

How do you update firmware on the T-Mobile gateway?

Checked my App. The current firmware version is 1-2003.03-0178. I guess it is auto updated to the latest version?

How do you update firmware on the T-Mobile gateway?

Just an FYI anyone searching this. It’s coming. But it’s probably going through checks and getting ready. But a device wouldn’t have gone through the FCC if such a device doesn’t ext.

Well, if you’re having issues with double nat (actually, even if you aren’t), I’d put a call into tech support and get your firmware updated. The number they gave me to bypass all those irritating menus is 844-275-9310.

Good luck!

BTW what issues were you having slow?

Unreal replacement gateway showed up you just swap the SIM to the new unit. Booted up says Celular HW failure does not get any bars. I called tech they we did everything now they think it is a tower issue really how would that be. They don't want to ship me another unit they are asking me to wait for an engineer to check the tower. I think it’s obvious I have another bad gateway and need a replacement.

So last night I got it to boot before I went to bed and I left it on. By the am it was rebooting and I got to log into it for a sec and I thing it got a firmware update as it did not have the same numbers but I lost connection. Now today I have kept it off cooled it on the AC vent and it just will not boot all the way makes it like 15 sec and reboots over and over. I see the replacement on my account hope it ships first of next week I need to cancel Comcast by the end of the month.

I feel like if I hadn’t said anything you’d be doing just fine! Sorry about that. Hard to believe these trashcans are really that delicate!

Na seems it was going to fail at some point best now and get another one that hopefully works.

Ok finally got someone that could help me and did not have to transfer me. They are shipping me a new gateway asap.

But I have determined that it is a heat issue. If I let it sit off for say 20 min it boots up normally but has stopped after several min doing the reboot. Yes I have the USB fan under it but seems this unit has developed some heat issue fan or no fan.

Maybe it did not like the new location I have not had it long enough to really know.

Bad news. First I was told a new firmware is rollingling out to fix the issues with 0178 but she says they cannot push it that I have to wait about a week for it to come.

She was nice and helped me actually find a good line of site to the tower that I am connected to.

So I of course had to unplug the unit to move it and now I am stuck in an endless boot. I see the T then dot dot dot then dot dot dot then reboot over and over. I have tried reseting it with the button holding it nothing works same issue. Removed the SIM reseated noting same issue.

Called support spent a while finally they tell me I need an exchange they cant help I have to be transferred then I got disconnected. Now again waiting for someone to call me so I can get a replacement unit setup.

I guess it’s a good thing I have not ditched Comcast yet or I would be totally stuck.

So on phone with them now they say there is a bug in 0178 that VPN’s don't work.

I wanted to update my post regarding double nat. I just got off of a very long tmo tech support call with a knowledgeable tech, who informed me that the 1.2003.03.0178 firmware resolved the double nat issue. 

Based upon this information I unpacked my Google mesh wifi and installed it. Thus far I’ve had no connection issues, testing out all my video subscriptions, Nest camera feeds, etc. 

The tmo trashcan is still at 192.168.12.1 and is reachable from my macbook connected to the Google mesh network with a 192.168.86.xx address, with router & DNS both at 86.1.

007BondMI6, can you check your firmware and also find out if you are still truly double nat?

 

I will check tomorrow when I get home.

I watched all of Nate’s videos. They are very helpful. One thing I would suggest for anyone starting off with a new T-Mobile Gateway is to not change any settings until you understand what the settings do. I made a bunch of changes, but that just caused me more work since I didn’t know what I was doing in the beginning!

There’s a guy on YouTube “Nater Tater” who has some reviews and other videos related to this. It seems double nat with your existing mesh network is the best solution for now, until a beacon comes out for the gateway.

I spent a lot of time looking for the best location to place my TM Gateway in my house so I could us it alone and so it would cover my 5000 sq ft two sorry L shaped house. Smack dab in the middle is the best. Only perfect near the middle, and the signal tapers off at the ends of the house. Even so, speeds are acceptable every where in my house. The best solution will be when Nokia makes a wireless mesh extender for the gateway. I look forward to that.

Yea maybe I will play moving it around once it comes but I have never found a single unit that would cover 6500sf 2 story colonial style house. The L shape I would think provides some advantage for single placement. No matter where I place a single unit there is a dead spot somewhere in the house. If I go for the center 1st fl it works the best overall but each end on the second fl is not really covered nore the driveway for the cars. The mesh system seems to be the only thing that really works and works well for every spot of my home. Funny thing is distance does not seem to be the issue walls seem to cause the most loss of signal. I do hope the mess units come out as a single package without the double NAT would be best I think.

Now back to some mesh stuff that I also posted yesterday but it was not posted since I had the link in it.

 

I really need a mesh system as no one unit regardless of brand is going to cover my whole home. Issue is home is large and long and I have smart bulbs outside too as well as cars that need Wifi. I have in the past tried so many Wifi extenders moving things and always something winds up being disconnected and not reconnecting. Finally a friend told me he bought a Google Wifi and it ended his issues so I decided I have tried so many others why not. Out of the gate like this TM gateway the Google is limited but at the least has port forwarding and some basic features. I can only state my results in my home almost 2 years since install and rock solid everything stays connected all the time no issues. It has been used threw the whole pandemic with everyone working from home and the kids taking classes from home no issue. Again your results may vary and the Google Wifi is quite limited in features but seems to work. It is connected to a Comcast modem in bridge mode.

 

Now my dilemma my neighborhood is contract locked to Comcast we cannot get anyone else. Whole neighborhood has fiber for Verizon but that was 15 years ago and still 10 more years to go till the exclusive contract is up. Can you believe that Verizon laid the fiber 25 years ahead of when they can offer the service. Anyways I don’t like Comcast for many reasons, coming data cap that they want you to pay for overage, bundles of services I don’t need, high rates as you have to have a bundle as individual services are way overpriced, inconsistent speed.

 

So with my contract with Comcast coming up I decided to go with my only other option T-M. Now when I decided to order I had no idea it was backordered till mid Sept as my Comcast contract expires in Aug.

 

I initially assumed I could use bridge mode so no issue with my current mesh but later I found out I was wrong. Now keep in mind I don’t even have my unit yet I am just doing research so when I get it I can get it working asap.

 

At this point seems I will be going with double NAT and see how it goes.

 

As for placement I have found out many things. First I downloaded an app to my 5g phone for testing. For sure the best signal is by a window with a huge BUT! Did you know that many window screens are made of metal? So that means if you have metal window screens you have a Faraday cage that blocks all signals. My screens are metal and removing them when testing signal almost doubles my signal by the windows. On the T-M site my home shows as Fair 5G and Good LTE this does not sound to encouraging does it. Using the app I could see the tower I am attached to so I would test on that side of the house. I tried all windows and found a second floor window that gave the best signal and speed. Further the top half of that window provides at the least double the download speed. Though I cannot see threw trees using the map I theorize that this window/spot has the best least obstructed line of site to the tower. Moving one window to the right or left drops things more than half. To prepare things I built a shelf on the window to hold the modem when it comes. I ran a cable from that area to where my Google Wifi is so I can patch that right in when it comes.

 

So lesson is if you want the best speed and connection it will take some time as not every spot is equal and moving just a foot can make a big difference. Windows do seem to be the best location with the screen caveat.

 

Imp don’t forget to check your screens if they are metal remove them as they are blocking your signal for sure. Just look up Faraday cage if you need to see why.
