5g/LTE connection and gaming ping, simple solution without QOS, will you do it?

[safwan264]

hi, i have 5G/LTE connection, it is slow, barely get 20 mbps and 15 mbps D/U during peak and this is when i want to game as well..........
i have used cake-autorate, cake, asus adaptive, but in theory it does not work and in reality as well does not work except cake-autorate. However cake_autorate maybe bogs down as well because it is using CPU and with too many connections it will succumb and will high ping.
My proposal is:
CPE - > mainRouter - > QOS limit bandwidth to AP - > all wifi from AP and only on mainRouter wifi for gaming.

Anything i am missing here?

One thing that might help with 4g/5g connections - drop the MaxMTU down a bit - try 1420 on the WAN interface, and step it up to where it breaks...

it is set to 1500 as default, i have changed TTL to 65, i have selected only LTE, because 5G NSA makes both speed and latency poor.

5G, even NSA, is going to be better than LTE because of service priority at the cellular base station...

and if you leave MaxMTU at 1500 - well, that's your choice, but it will fragment packets there...

TTL really doesn't matter at the WAN side for 4g/5G these days - used to, but with 5G and 5G-SA deplpyments, that workaround is basically dead-ended...

ok , following your advise here is what i did and its result:

1. disabled TTL = no change, kept it disabled.
2. played with MTU, with LTE only mode the ping -f -l 1472 8.8.8.8 worked fine, but beyond this "fragment error".
3. with 5G NSA, the MTU changed itself! and then 1464 was new max, beyond this "fragment error".

The speed is different with both modes:
5G-NSA
CA BAND: B3/B1/B41B41N77
RSRP: -86dBm
RSRQ: -10dBm
SINR: 29dB

LTE only:
CA BAND: B3/B1/B41B41B41
RSRP: -85dBm
RSRQ: -10dBm
SINR: 17dB

Does your table tennis game work well with this high latency?

Does your table tennis game work well with this high latency?

so far i am just testing, because i was before on H155-381, balong 5000 based CPE, and problem was ping acceptable but in between were major lags which almost made it unplayable. With my new setup, suncomm 08 ultra, RM551 based CPE , things look better, the above screens are from new CPE which is not yet connected to the house AP. so i am the only one using it.
I will test game on this new setup. With wifi behind AP which is getting all internet from ASUS 58u, which is set QOS at 25 mbps. While i will connect direct to suncomm wifi and see what happens. If this fails, then i will leave this new setup for AP and simply use the balong5000 CPE provided by ISP only for gaming.

Not a gamer, but bandwidth is most likely not your issue. Real time games need low latency.

i have been testing cloufdfare detailed speedtesting:
1. behind the asus QOS, i score bad on gaming and poor on video.
2. direct with RM-551, i score bad on everything.
3. with my balong 5000, i score bad.

maybe i would just keep two sims, one for home and as LTE for maximum speed and other only for connecting to quest 2 for gaming only. This has been my setup, but i wanted to save on that second sim, but it seems i have to keep two sims.

The same type of Internet connection - the same issue. Most likely both connected to the same cell tower as well.
