Re: Full configuration of DHCP and other network services
Hello folks, I'm another technical user, with RF experience and telecom background, along with IT and electrical engineer >20yrs. I went looking for PLEX and KVD21 remote access, that may be the only bust but it is what it is. I had tried out the trashcan device, and returned it after getting ATT fiber. BUT now ATT is doing the "bait and switch" with promo expired and "no promotions currently available" game. Similarly with Spectrum (cable), but I lose power frequently in my neighborhood and that kills the cable signal (regardless of home UPS/generator). ATT has a similar issue but they at least have some kind of UPS setup (so fiber is active during brief power outages). Have to use their huge device (BGW320-505); it's better than previous models and does Wifi6 (802.11ax). My issue is needing internet during power outages (ring doorbell!). Great current deal on device, in addition, they have a promotion for $100 gift card for new service from 11/10/2022 - 1/11/2023.30Visto0likes0ComentariosRe: NOK 5G21 Gateway Battery Backup
Wow that is incredible…could be the switching power supply is most efficient at full-rating but with something like 1.25A (12V @ 15W) it seems that your measurements show it's less than 50% efficient. YUCK. Then again, there may be additional inefficiencies when considering the 12V to 110V power outlet and then the 110V to 12V plug-in power adapter, combined. Assuming they're identical, then each conversion is 68% efficient (square root of 7/15). Even that is pretty low IMHO.19Visto0likes0ComentariosRe: NOK 5G21 Gateway Battery Backup

This power station has a variety of outlets: 110v for electronics and appliances, also 5v USB jacks and three different types of 12v jacks. 110v toT-Mobile Gateway ≈ consumes 15 amps≈ backup power for38.4 hours 12v to T-Mobile Gateway = consumes 7 amps = backup power for 82.3 hours. So, during a power outage, it's not likelyI'd power the gateway for 24/7, but I could theoreticallystream video to a tablet and keep tablets and phones charged for 2-3 days using only the power station. https://ecoflow.com/products/river-max-portable-power-station?variant=39335175979081 Do you mean 15 Watts, and 7 Watts? That makes the math work, but it may be much less due to quiescent power losses (i.e., nothing connected, power consumed by power supply and circuitry) and inefficiencies (Pout/Pin = approx 80%). Most flyback power supplies are the most efficient near full load, mostly due to minimization of the quiescent losses (they're still there but much less than power delivered). Many of these power supplies calculate the watt-hours by multiplying the nominal voltage by the amp-hour value of the batteriesbut the actual measured power supply delivery duration is often much less.9Visto0likes0ComentariosRe: Feature Request - Home Internet Gateway DHCP Settings
I agree with you 100%!! As a workaround, many people (including me) have asked for a bridge-mode and perhaps the first device connected via LAN port (since there's no WAN port) gets a WANIP address, and other devices plugged in do not receive an IP address (from TMO WAN), in a similar mode as cable modems with either two or more Ethernet interfaces or connected to an Ethernet switch. My issue is that TMO doesn't work with UPNP, which breaks my paid PLEX service. It is irritating too to have to continue to "guess" the IP addresses (as they change) for things like my desktop when using RDC technologies (i.e., VNC). I have been using ASUS AiMesh technology on an RT-AX3000 and that works really well. The only issue is how to access the TMO management interface (for signal quality, battery level, etc.) we need a special IP address. For cable modems on some services, you can access this (i.e., QAM allocation, channels, SNR, etc.) is accessed via http://192.168.100.1(even though the LAN can be192.168.1.1). In other words, the cablemodem filters ARP requests for 192.168.100.1 to itself (not sending it upstream because it's not on the LAN interface). Not sure if telnet/ssh access would help, unless we knew how to modify the routes, how to save them (from power cycles / reboots when firmware updates are applied) in NVRAM/flash…lots of deep technical questions, all of which could be eliminated if we had a bridge mode and used our own router. In the interim, the bridge mode would allow those users to support themselves and their own particular flavor. Opening up the router to other firmwares may be potentially risky and brick-making. I'm just trying to justify TMO reasoning if they don't allow this. It's similar to mobile carriers invalidating warranties for phones with 3rd party firmwares. There is a non-zero chance of hardware damage occurring. For instance, let's say the power amplifier has software feedback to prevent thermal runaway, and that is somehow bypassed, now the device could be damaged or worse, it could be that its damage causes harmonics that are affecting others'mobile services. Similar reasoning could be for the LNA, in that it could be controlled to overload the radio receiver and irreparably damage it. AT&T fiber requires using their router, and their justification is "to make sure our service is working normally" (whatever). However, they do provide a bridge-mode, and if you also turn off wifi, you can then use your own router and the WAN IP is presented to the first device connected on the LAN port. That undoes any restrictions and limitations imposed by using their router (i.e., no static DHCP, no DDNS support, etc. etc.).24Visto5likes0ComentariosRe: Feature Request - Home Internet Gateway DHCP Settings
I think this is called "static DHCP" meaning the IP address given by the DHCP server on the HIG is based on MAC address. DNS-based content filtering I believe means the HIG serves as first-layer DNS server based on local devices and based on their "friendly" name provided before contacting the external WAN DNS server (hosted by TMO). All of these features have been available for probably more than 10 years in OpenWRT, DD-WRT, Tomato, and other variants, many of which are open-source.26Visto1like0ComentariosRe: Suddenly slow home internet.
You mean 100 Megabits or 100 megabytes? 12Megabytes = 100 Megabits. Download speeds from the browser are most often given in terms of bytes/sec but ISPs provide speed in bits/sec because it looks better :) If you are getting 100 MegaBYTES/sec that would be 800 Megabits/sec. That's kick butt!! Almost as fast as Google Fiber's 1Ggiabit/sec service. You'll get the best link speed if your device is as high as possible and away from solid metal surfaces by a few feet (i.e., don't put this on top or right next to a metal filing cabinet).47Visto1like0ComentariosRe: can the following features be added to the 5G Home gateway?
I can't agree more! QOS is important, and for me, UPNP, for PLEX mostly. Or, better yet, until these features are added, just allow the device to be in bridge mode so then we can choose the router with these features. However, it remains to be seen if UPNP would work due to TMO's network configuration (something to do with IPv4 over IPv6 I believe?). Another useful feature would be static DHCP, especially for things like NASes or RDP/RPC. That might bring this thing up to the range of features which has been provided by dd-wrt for probably a decade or more?12Visto1like0ComentariosRe: NOK 5G21 Gateway Battery Backup
Agreed; the previous 4G-LTE device had a battery which maintained WiFi connectivity during power outages. This functionality didn't carry over to the 5G cylinder device from Nokia. Many of us, including myself, relied on the built-in battery backup for power outages lasting on the order of minutes to hours, for things like ring doorbells or NAS devices (Plex) using UPNP (neither of which are supported by this 5G device).13Visto0likes0ComentariosRe: Plex Remote Access Unavailable.
I guess you could configure Plex for VPN access but not sure if there is a way to do this. I have Plex on my NAS, and I couldn't find a way to do this (except for VPN'ing everything, which I obviously don't want to do on my LAN). Anyone else have any solutions? I thought the problem was UPNP not supported (router). Router behind the TMO router won't help either without TMO router (trashcan) supporting UPNP.35Visto0likes0ComentariosRe: Thermal Issues With Home Internet Gateway/Router as a Cause of Dropped/Slow Internet or Wi-Fi Connection
As another datapoint, I received my gateway in early September. So far it has worked better than what I had expected, albeit not supporting uPNP (PLEX),no help from the UPS port, and no idea about the mesh functionality requirements. I am also an EE PCB designer. I'm using a 12VDC battery backup UPS designed for 12VDC telecom equipment to power the gateway (as the internal battery is configured to drop WiFi when power is lost) for my ring doorbells. Wish I was in the 5G Ultra area but I'm in the extended area. Speed tests are generally around 150Mbps down, 40-60Mbps up. LOTS of packet loss when I first turned this on and tried, but after 30 mins, re-trying I still see 0.0% from speedtest.net site. From 192.168.12.1: hardware version =3TG00739AABB software version =1.2101.00.1609 "Running Time" =3d20h56m (as of 2:22PM EST) Cellular "Data Sent"6.03 GB"Data Received"76.60 GB (Wifi is significantly more - NAS) Location: 2nd floor in a closet on top shelf, in a conditioned house No fans, no metal objects within 3 feet. Nothing loose (BTW the heat sinks should be retained toPCB via wire, otherwise they could short internal components and perhaps cause a fire (very unlikely but not impossible).10Visto0likes0Comentarios
