Hi, welcome to the community. Thank you very much for your time and patience.

• Full manual band selection / locking

Have you tried to manually search the available LTE bands here:

• Control over band aggregation behavior (e.g., choosing when and how bands like B1 and B3 aggregate)

There hasn't been a beta firmware that allows customizing the Carrier Aggregation bands. It is not only related to the mobile router, but also to the current network bands' capacity of the connected cell(such as whether certain bands are crowded).

Thanks a lot.

Best regards.

Hi, welcome to the community.

I'm afraid there hasn't been an option to lock the Carrier Aggregation bands on the Archer mobile router.

The success of certain Carrier Aggregation combinations highly depends on the current mobile signal strength of the SIM ISP. If the signal is noisy, the router will focus all its energy on maintaining just one stable connection rather than trying to juggle several unstable ones.

Thank you very much.

Best regards.

I’m using the Archer MR600 v5 (Firmware Version: 1.1.0 0.9.1 v0001.0 Build 240830 Rel.58384n) and I would like to ask if there is a beta firmware version available that allows:

• Full manual band selection / locking

• Control over band aggregation behavior (e.g., choosing when and how bands like B1 and B3 aggregate)

• Preventing the modem from disconnecting or reverting to single band when idle or under low load

I am aware that some older versions (v1/v2) have beta firmware with these features enabled. It would be great to have the same level of control on v5 hardware as well.

This is especially important for rural areas with specific signal conditions, where manual band locking provides much better and more stable performance.

Please let me know if a test firmware is available, or if such functionality is planned.
 

Thank you in advance.

 

I would class  the mr600 v5 as don't bother. I bought it used it for one day and went back to my mr600 v1 which I can use  with beta/test firmware as follows

Archer_MR600v1_1.1.0_0.9.1_[190412-rel66770]_up_boot_2019-04-12_18.39.25

Archer_MR600v1_1.1.0_0.9.1_[200417-rel75138]_up_boot_2020-04-20_08.44.31  (old but BEST for my purpose)

Archer_MR600v1_1.2.0_0.9.1_[200511-rel44954]_up_boot_2020-05-11_16.11.10 (standard auto, but carrier aggregation is permanent on, Checked with speed test, running on Telstra AU Band 7,3 beautifully and stable. I am around 800meters away from the tower)

Archer_MR600v1_1.2.0_0.9.1_[220818-rel55981]_up_boot_2022-08-18_15.34.47 (don't bother, rudimentary)

I really believe that its a joke that carrier aggregation switches on during a speed test but otherwise its off

just uploaded the firmware to mr600 v5. Yes, its working as expected, but there is no way back to the previous version. But still no carrier aggregation permanent on= still useless. My Location is Australia
