Hi ASUSmy,
Does AC1200G+ support android usb tethering?
Because i tried using galaxy s4 for usb tethering but the result is no internet connection.
I also tried FAQ troubleshooting but still the same problem.
Hope someone can guide me.

this is the error after random reboot:-
Kernel panic - not syncing: Out of memory: system-wide panic_on_oom is enabled

logfile already sent via pm to asusmy for help

Try disable NAT Acceleration if you don't use any lan port.

just flash back 3.0.0.4.380_7743 , now entering 13th hours tongue.gif
rclxms.gif hopefully no issue until another new update ? lol
will try your solution if friend's unit got problem
thanks !

Hope it help tongue.gif

But don't put too much hope of this router...
Firmware is shit since release, example from the first one until 380_7743 the router will random reboot around one weeks(or less), after 382_xxxxx firmwares wifi not stable when speed up to 100mpbs(feedback from other users) and if NAT Acceleration is enable the memory will leaking over time and then crash the router....

Which one is your firmware that reboot with kernel panic message? 380_7743 or 382_18991?

Btw do you have any chromcast devices?
Because I just found out this articles, not sure is it related or not....Known Issue: Slow Wi-Fi performance with Android and Chromecast built-in devices and TP-Link Archer C1200 WiFi Disconnects Issue and Resolution


Erm...those info has been post by blacktubi....

I wonder what happen to the AC1200G+

When I still have mine, it is still fine and I don't face any weird issue.

I guess people should get the RT-AC1300UHP directly now.
*
Maybe those problem is because of defective product?
But cannot reproduce the problem during RMA test so just live with it....

both 380.7743 and 382.18991 with random reboot issue.

upgraded from 7443 to 18991 then downgrade back to 7443 again.
all upgrade and downgrade comes with factory reset , no added on USB devices or running any built in features.
it just apple and android phones connecting via Wifi (less than 10 devices in total) + one PC running on LAN.
i would say less streaming in my case , maybe some watching of videos on youtube.
no on going BT download.

Using N12 D1 and N12HP previously without any issue , but of course that is not an AC router

Will try to do some changes on Wifi setting , and see if it works.
meanwhile wait for Asus representative feedback  laugh.gif

I'm sorry can't help you.... sad.gif

Lets wait asus representative to reply you/us this issue.

downloaded while waiting for kernal panic again , but it has been up for 17H since i update from 380.7743 to 382.18991 again , but without factory reset

I'm wondering when is your router start acting like this? Since bought or just a few weeks ago?

After 9 hours of using that 382_39963 firmware, the first thing I noticed is status in web page work again! (18991 will redirect me to the log in page rclxub.gif )

it happens every 2 or 3 days before this , it's not that frequent until 380.7743 update then 382.18991. i notice kernal panic every 6 - 8 hours.
Max online time on router is less than 24h. i don't mind restart of router but it's too frequent  rclxm9.gif

btw , it's more than a day now on 382.18991 . haven't try the file gave by AsusMY yet. it's still same devices connecting to same router so i wondering what makes it resources hungry or some other reason?

Hi everyone,

Is it normal that my ASUS router(AC1200G+) when connect to 2.4Ghz wifi only has half of the speed compare to another HUAWEI usb modem router(E8372)?
It seems like there's something limiting the speed of the ASUS router. Because sometime the speed can same as the HUAWEI router but sometime it just stuck at around 10Mbps.
Both are 2.4Ghz wifi, same location top of the 2 meter height cabinet.

If connect to 5Ghz wifi on ASUS router is fine, speed is very fast and stable, just 2.4Ghz wifi act weird.

Thank you

The Asus seems to have a wider coverage, so it has more interference/congestion from other wireless signals. 5Ghz is fine, as there are less congestion and interference on it. See here: https://www.howtogeek.com/222249/whats-the-...should-you-use/
*
Wider coverage, hmm make sense maybe this is the cause of slow wifi speed, I forget about the coverage thing just keep thinking there's not conflict in channel but speed still slow mega_shok.gif .

QUOTE(JohnLai @ Jul 4 2018, 12:43 PM)
Because you are setting the channel bandwidth as 20Mhz instead of 40Mhz or 20/40Mhz (co-existence)?
*
Isn't 20Mhz much more better when there's interference or in high congestion place?

QUOTE(wind01 @ Jul 4 2018, 02:29 PM)
For AC1200G+, for a start: -
1. Untick b/g protection (unless you have some legacy devices that need to be on WiFi)
2. Disable "Airtime Fairness"

Save & reboot router. On device, forget Network & re-enter Network credential to connect. See if the problem persist.
*
After disable "Airtime Fairness" the speed is slightly better than before can go up to around 25Mbps, but I didn't untick b/g protection because it's only available for untick when using "Legacy" 2.4Ghz wifi mode means max throughput 20Mhz/54Mbps, and the result is .... much more worse than before .... laugh.gif

Thank you everyone for you advise. notworthy.gif
