Was wondering the same myself... I just dug out my old 12 HP after having some problems with the D-link AC 750 (Dir 816). The answer to your question will depend on what Revision of RTN 12HP you got.. If you have the B1 you can flash the latest which is 3.0.0.4.378.9443.
This leads to my question addressed to ASUS MY.. Both revision of the router started of using same firmware version numbers, with the first upgrade to 4018 fixing the same issues.. The B1 then got 3 more updates to the current 9443 with numerous security and other upgrades... Does this mean that the non B1 revision is still lacking the following??

Is the non B1 Rev safe to use without all these security updates??

Thanks for your help

MYAsus,
Have you had a chance to look into this yet?
Cheers

AsusMy,

Does this ring any bells???

ASUS Malaysia is glad to officially announce the immediate forum support thread for ASUS Networking Products. In order to provide the best support, we have position one dedicated staff to monitor as well as provide support to all existing/new ASUS Networking customer. ASUS Malaysia striving for the best. Cheers.

Have you been the "face" of Asus on these forums for the past 2 years? If so I can understand your lack of motivation.. Same questions day in day out.. Maybe its about time for a substitution??

Anyway, I'll ask this for the last time... Have Asus stopped support for the non B1 RT-N12HP?? I've been using it for the last 4 days, but it has started dropping connection again..(Latest firmware - 3.0.0.4.376_4018 and reset done after update). I don't want to go back to D-Link or try another brand, BUT I would like an explanation for the discontinuation of updates prior to investing in another Asus.

Your acknowledgement would be appreciated

Thank You

When using a network cable from laptop to my RT-AC55UHP with USB 2 storage connected I'll get around 22 MB/s. It's a lot slower when using the Wifi, only approx 4.5 MB/s.. My laptop is quite old though, Have been searching for a replacement wireless card but can't find one locally, will maybe buy a USB AC adaptor..

I've got the AC 55 UHP and its covering that size no problem whatsoever, it's not even placed in the ideal location either..
This is by no means a high end router but when you start going cheaper you are sacrificing on the chipsets and amount of RAM, you might then start to lose the stability that you desire..
Cheers

Hi,
Is the above firmware final release? I installed on my unit but noticed the CPU usage was stuck at 100% and RAM around 80 MB used.. Reflashed to original which fixed the CPU but my RAM is still hovering around the same, only 40 MB left.. I can't remember if it was the same before the flash.. Is this RAM usage normal?

Apart from that the router is doing a fantastic job covering quite a large house with 15 to 20 clients connected

Cheers

My apologies, quoted your wrong post with link...

I'm using the 55 UHP and flashed RT-AC55UHP_3.0.0.4_380_1192-g3298f1f.trx

Thanks again

We have just moved home and waiting for unifi installation, during this time I have been using the hotspot from my phone for Internet..but it is not great coverage...Google says I am supposed to be able to just plug the android phone into the usb and turn on the USB tethering then I can share the phone connection through the router afterI have selected USB WAN in the Asus setup page 192.168.1.1...
Have tried with 2 different phones and it's still not working???
Has anyone used this feature on the 55UHP before?

ASUSMY,
The last time you pointed to a new firmware release for this router... It still isn't on the global site?? Any idea if the beta is safe to use?
Thanks

Thanks jpong1.. Are you experiencing any of the issues I mentioned above? I never received an answer from ASUSMY on it..
Cheers

It was the router CPU that was high for me...

Anyway I've flashed this newer build of the beta and it has sorted out the high CPU usage. I can also now use the USB tethering from Android... Thanks MYASUS

AsusMY,

I have to use my unit in AP mode since we now have streamx until unifi install a new port..
Anyway, when I connect to the WiFi (AC 55 in AP mode)with my phone it causes my iPad to lose connection to the internet( still connected to the router) as soon as I turn off my phone WiFi the ipads internet connection is immediately restored...
Using the latest Beta as provided by yourself... Factory reset done after flash. Twice 😉
Logs attached...
Thanks

I posted this https://forum.lowyat.net/topic/4357218 in hardware forum, can someone' that owns the 55UHP help me out please?
Cheers

Thanks, but not any 12V - 2A will work.. I need someone to confirm the polarity of the barrel plug..



If the transformer doesn't have any of those symbols, could someone check it with a multi meter?

Thanks mate
