Okay I will edit it later when I get back home.

When I was doing on my side here, I must've use a different MTD-Write from different guides. Either Step 9 or 10 which I tried didn't work. So I just used both to be sure.

I've edited my post with new links and instructions. Please try again.

Weirdly enough, now my Internet LED lights up green eventhough it's on AC68u. Seems to have fixed itself.

New firmware update for Asus Merlin. Now version 386.2.

https://sourceforge.net/projects/asuswrt-me...-AC68U/Release/

I've updated my guide to include both CFEs for 2.4g WiFi fix. OP, please test and you may add a link to it at the front page.

1 file for converting to AC68U, 1 file for remaining on AC66U_B1.

As for my usage, I don't find any much real life difference between both models.

Seems like DIR-868L after the 2.4ghz fix is on par with the Tenda units. On the other hand, something is really wrong with the Tenda AC11 5ghz. It's like you're getting 2.4ghz speeds.


Here's my speedtests. I'm on Unifi 500down / 100 up. Test done 5m away from router. Direct line of sight.

This is the best I can get using DIR-868L converted to AC68U on 5ghz. My phone is 1x1 antenna. So link rate is 433mbps.

Unifi 500 down | 100 up. Distance about 3m with 1 brick wall in between. Going nearer doesn't make much difference.

I think the limitation is my phone. My phone is only 1x1 antenna. DIR-868L is 3x3 5g antenna. Max link rate of 1300mbps. Real life best speeds usually around 50% of 1300.

So technically it can max out my Unifi 500mbps if my phone/laptop/wifi adapter has 3x3 antenna config.

Looks like your repeater/node is placed a bit too far from the main router. My 2x2 repeater placed upstairs can maintain at the best theoretical rate 867mbps.


For my DIR-868L with 3x3, can't get max of 1300mbps. Can get 1000+ or around 900



This is my previous setup. Asus AC55UHP as repeater. Since it's a 2x2 antenna WiFi, 867mbps is the best link rate.

Can you see what's the link rate for WiFi4 on your device? Based on specs, AX50 is 2x2 antenna for WiFi4 whereas DIR-868L is 3x3 antenna for WiFi4.

And are you comparing with fixed DIR-868L or before the 2.4g fix?

Comparing to my DIR868L after the 2.4g WiFi fix, I'm getting similar performance with yours on 2.4g WiFi.

However, seems like 5G on the AX50 is performing better than the DIR868L.

Tested on my Xiaomi Redmi Note 5 (1x1 antenna, 5g @ 433mbps, 2.4g @ 72mbps)
2.4g I'm getting same results as yours.
5g I'm getting at best 270mbps. Only reach 300 with line of sight of router. Your screenshot shows that you're maxing out your connection's 300mbps repeatedly on 5g 1x1.

Unfortunately I don't have other 1x1 433mbps devices to test whether the router is the limiting factor or perhaps my phone is old?

I know wireless device performance differs eventhough they may have the same antenna configuration. My TP-Link archer T4U WiFi adapter specs is 2x2 @ 866.7mbps but it can never get above 250mbps no matter what I try. On the other hand, my gaming laptop with 2x2 @ 866.7mbps WiFi, can reach up to 400mbps.

Next follow my guide at post #98 to fix 2.4G wifi. Choose the AC66U_B1 version

https://forum.lowyat.net/topic/5079525/+80#

Both is fine. But just stick with AC66U_B1 so that LED works.

Did you change all 3 mac addresses and Secret code in the CFE?

Will be back to full speed as per before conversion.

You can't use the default one. Default one is 123456789. You must use back the WPS code written on the sticker under your unit. Then only AiMesh can work.

Are both routers using the correct mac address and WPS PIN as shown on their respective stickers?

For the 3 mac addresses, did you use the same address for all 3?
1:macaddr is supposed to be a bit different than 0:macaddr and et0macaddr.

Cannot cannot. The MAC address has to be different.

Follow the initial guide in the first page when you're doing the conversion.

2 of the MAC address is same number. The 3rd one need to +4.

1:macaddr needs to plus 4 on the last number.

Otherwise your aimesh might not be using 5g backbone. Makes sense why LAN works because LAN is the correct macaddr.

0:macaddr change to x.x.x:29:B8
et0macaddr change to x.x.x:29:B8
1:macaddr change to x.x.x:29:BC

The rule is follow your router's sticker but plus 4 numbers.
Convert the HEX number to decimal and then +4. Then convert back to hex number.

Yours is B8 is hex number. Convert to decimal is 184. Now we add 4 and it becomes 188. Convert 188 back to hex and it becomes BC.

0:macaddr change to x.x.x:29:B8 (Follow router sticker)
et0macaddr change to x.x.x:29:B8 (Follow router sticker)
1:macaddr change to x.x.x:29:BC (Convert to Decimal, +4, convert back to Hex)

Where are you buying yours from? Are you from Johor? I actually have 1 extra unit to let go. Still under D-Link warranty.


Since AC66U_B1 and AC68U using same firmware, as long as they keep supporting AC68U, we should be fine. Asus Merlin will also keep supporting as long as Asus supports.
