I think someone needs to put a warning or something here to warn others not to sign up the router bundled package.

I'm going to try using the mc888s with WiFi starting today since mine no longer dc or reboot. Since the wifi is rated at AX5400 which should theoretical be better than my Tplink AX50. Let's see if the additional heat from the wifi usage will make it hang.

If everything works, then only I consider making a custom case for it.

but for me

the mc888s Wifi range is not as broader as Maxis Kaon router since both do not have external antenna.

It is still okay for me though. My router is placed on my sofa, right beside the window. My Tapo C210 in the back alley still can get the 2.4GHz signal and playback video. This is good enough for me already.

Update: 2PM

well, it seems like the router had the first restart after enabling the wifi. It looks like it is still a better choice to just go buy a new router if you dont have a spare one to use as AP. I guess there is just too much for this poor router to handle. Once the 3 of us starts to game at the same time, it only took an hour to crash it. Switching the wifi off again and back to using AX50 for wifi.

So basically the router having hard time to cope with both the 5G and Wifi work, use it as just a 5G modem and it lessen the load?   

Dual network? How did it show both 4G and 5G?

Yeah, it seems like while MC888S is usable but only for 1-2 light users. The router will work just fine until I game together with both my sons. One of them playing Valorant, one playing Roblox and me playing Pixels + discord + youtube. Then it would occasionally hangs every hour or so.

After I did the thermal pad mods, it still dc after even when I had a 120mm fan pointing at the 5G card area. Only with my latest mods with two 120mm sandwich the router which was strip naked then only it would not dc. I guess ZTE really under estimated the amount of heat produced by the IVY510 chip. I wonder if anyone would try to peltier this beast since you can find these going for very cheap in Taobao nowadays. Its fun to finally conquer this blardy chip but not easy.

5G is down in my area. The router is showing 4G or 4G+ despite network settings to 5G NSA.

Ghee ....

Check with your phone is easier

Placing modem near window = myth?

For the past one year, I have been placing my modem near window in my master bedroom since L.O.S of the tower is about 500m away and the outcome is as follows:
Signal Strength: 4 Bar
RSRP: -91dBm
SNR: 4dB
Average speed: 250Mbps

Out of curiosity, I decided to test and move the modem to the 2nd floor hall where there is no window and position the modem to another tower behind my house about the same distance. Lo and behold

Signal: 5 Bar (full)
RSRP: -85dBm
SNR: 10dB
Average speed: 420Mbps

It is not a myth. Try placing the router directly next to a wall and try again. If you are in lower floor in a condo or double storey house, surrounded by walls, it is best to place the router next to a window. If you are on 2nd floor of your double storey house, chances are the signal can still penetrade the roof tiles which is easier to penetrate than that solid 4-6 inch of walls.

Ermmm.. the router is placed next to a wall..and the result are significantly better than previous location which is right beside the window.

I think it is safe to say that ZTE mess up this router very badly. Perhaps it was not designed to handling such load. Even the 5G alone also make it dc/hang sometimes if you dont dismantle the cover to cool it. I think they totally skimp the cooling for the router which causes it to overheat very easily. Even after I change all the thermal pad to a bigger one, plus 2x 120mm fan cooling both top and bottom heatsink, I still encounter problem sometimes. Yes, it no longer DC/reboot but sometimes there is some throttling going on (hard to say which chip) but it will slow down to 30Mbps max.

you gave me an idea for my next project. i'll get heatsink for modem card and thermal conductive tape with cooling fan.

I guessed the router just show the strength of the signal. It is actually connected to only 1 band at a time.

My family members don't game, don't download, we are consider as light users. Just casually surfing XHS and youtube, even during my wife home alone, although she just use the browser to read her novel, the shitty MC888S just can't handle it, always face disconnection.

The 5G speed itself nonetheless is awesome, get the ala carte and refrain from signing the bundled router will do. Screenshot attached below shows good router can do wonder even the signal is not at its best state.

which olax modem you used? thinking to get one for my parent's house
