No, my problem is ostensibly with the RT2600ac Router. It cannot see the 5Ghz Wifi band SSID of the 5G TMobile GW in its (the RT2600ac’s) list of prospective parent GWs. The RT2600ac can see and connect to the 2.4 Ghz Wifi band of the 5G TMobile GW as a parent router. The 5G TMobile GW works great; my phone, 3 firesticks, and my wife’s laptop can find and connect to either Wifi band with good throughput. The tech from synology recommended I down grade the 802.11 Mode from “ax” (Wifii6) to “ac” (Wifi5) to see if that fixes the problem. I need the RT2600ac Router to provide wired ethernet to my Desktop. At least one other TMobile product, a 5G hotspot has the capability to change the 802.11 Mode from “ax”. I was looking for a backdoor config capability of the 5G TMobile GW to achieve this type of change. I have concluded at this point that it is not possible and can live with the 2.4 Ghz Wifi speed limitations.
I think you’ve gone off topic. This is a connectivity issue not a performance one. I get decent to very good performance through out the house. I should have mentioned, I moved the 5G TMobile GW into the same room as the Synology router, not even 15 ft away and still the 5Ghz Wifi Band SSID did not show up in the prospective parent GW list
CORRECTION: what happens on the cellular side should NOT impact connectivity on the Wifi side of the GW
Here is what you requested. The signal strength screen is very good. RSRQ -10, RSRP -96, SINR -10. I do not believe that a weak 5G signal is the issue; what happens on the cellular side should impact connectivity on the Wifi side of the GW; it may impact performance, but that’s not the issue here. In any event an Ookla speedtest on my cellphone which readily connects to the 5Ghz Wifi band reports 248 Mbs. The phone is less than 3 feet away from the RT2600ac Router
Thanks copz1998 and nc1037: There some more information I need to provide. I am switching over from Startlink due to cost. The Synology router has been configured to run in Repeater mode while I have been on Starlink for 2 years and is configured like that as I switch to the Tmobile 5G GW. It has worked fine on StarLink which is Wifi5 I believe. In Repeater mode, the DHCP server along with a lot of features are disabled, i.e. the parent GW hands out IP addresses. The Wifi diversity and beamforming functionality still operate by default. Since the Tmobile 5G GW is on the second floor and my office space is on the first, there is no wired ethernet and I don’t plan on any, so wireless is the only way to go. I forgot to mention that I split the Wifi bands on the TMobile 5G GW each with a unique SSID, so I could control the reconfig on the RT2600ac. So after a “reset to factory settings”, I am able to configure the TMobile 5G GW 2.4Ghz band successfully, i.e. the RT2600ac searches for pote
I am unable to connect the 5Ghz WIFI band on my RT2600ac WiFi Router which is Wifi5 compatible. I contacted tech support at Synology re. this issue. he recommended I change the 802.11 mode from “ax” to “ac” for this to work. There does not appear to be a way to change this setting from the T Mobile Internet App. Form the internet, it appears other Wifi 6 compatible TMobile Gateways/Hotspots have the capability to change the “802.11 Mode”. Is this possible with the TMO G4AR gateway?
I just recently received the C4AR GW and have experienced signal issues not completely as expected when I signed up. Have you looked at the Cellmapper website for towers in your area: https://www.cellmapper.net/. This information is based on user contributed information which I found useful and mostly accurate. The FCC also has an official database that’s searchable: https://wireless2.fcc.gov/UlsApp/AsrSearch/asrRegistrationSearch.jspThe search feature on the FCC website seems to have some nuances which I have not yet mastered, but is supposed to be the official record of every tower. But I can still find towers in the DB I drive past every day. The elevations seem wrong to me, but my judgement could be off. Also bear in mind a lot of towers are owned by third parties that rent out space/elevation to major carriers, Good luck. Please fill us in with your results.
