Tags: #Firmware Update #Band Selection #Carrier Aggregation
Model: Archer MR600  
Hardware Version: V2
Firmware Version: 1.7.0 0.9.1 v0001.0 Build 220826 Rel.58057n

Greetings,

 

After updating to Version 1.7.0 yesterday, carrier aggregation is no longer working. 

Logs showing these in a loop:

2023-06-02 19:42:56 [6] 4G: USER: Network type is LTE.

2023-06-02 19:42:58 [6] 4G: USER: Network type is LTE PLUS.

 

I wanted to downgrade my Firmware to 1.6.0 for which i have the firmware but the official page of MR600 no longer has this firmware so i don't know if i should flash it or not, because after reading some threads it seems like the device cannot be unbricked.

 

I have attached the logfile also. I wanted to know if downgrading should resolve the issue or if it is safe to do so or even if downgrading will do something because ISP cannot be downgraded.

 

[EDIT] I have also performed a factory reset after upgrade.

[EDIT 2] Downgrading to 1.6.0 instantly fixed Carrier Aggregation issue. I don't need to access my router from the cloud so i think i will not upgrade back.

[EDIT 3] Before the update my router was sometimes appearing offline on tether app, but after the update my router appears online everytime i try to access it using cloud.

May I know your current firmware version? and if it shows 4G+ now after the downgrade, please also check the band on Advanced->Status page to see if it works on one band or two bands.

My current Firmware Version is :

1.6.0 0.9.1 v0001.0 Build 220105 Rel.58321n

 

It is now showing 4G+

Its currently on bands 3,40

 

 

When the router was on 1.7.0 then 4G+ indicator kept blinking in 2 seconds interval.

Hi everyone,
I also have the same problem with the new firmware....unfortunately I can't reset the modem, I was wondering if it was possible to downgrade the firmware to the previous version without resetting the modem:
I downloaded the old firmware 1.6.0 from the official tp-link site if I try to install it, does it succeed or does it freeze because it understands that it is older than the one currently installed?

If your device can be downgraded then it will be downgraded, otherwise the device will just give you an error (In my case, i can downgrade to 1.6.0 but not to 1.5.0).

You will lose your settings if you downgrade. In most cases downgrading is allowed, only exception is if the update contains some CVE patches then downgrading isn't allowed.

Blinking 4G+ means band are not locking.

The router is continuously switching between 4G and 4G+.

Downgrading will not cause any issue.

But make sure there's no power cut during downgrade. I have a ups attached to the router so i had no problem with it.

Hi everyone,
in the end I downgraded to the previous firmware ... by downgrading, however, the router returned to the initial settings, luckily having made a backup I was able to restore the settings as I wanted.
The question now is:
When will TP-LINK issue a new firmware that will fix this problem on firmware 1.7??
I did the downgrade to recover the 4G+ but I have the problem of the previous firmware, i.e. that from the App Tether even if the router is actually connected to the internet from the app it is inaccessible...
Remove a problem and find another ... when a firmware finally done well and not with the feet???

Hi，since we are unable to reproduce the issue on our end, may I know if you would like to debug the issue with our senior engineer? If so, we will follow up your case via email for further testing and analysis.

 

In addition, may I know the model no. of your smartphone? and if you insert the same SIM card into your smartphone, does it show 4G+ all the time?

Hi, I would love to help out.

 

My phone is Samsung Galaxy A73 5G (SM-A736B/DS), it shows 4G+ most of the time, i lose 4g+ when raining heavily, otherwise its consistent 4g+.

 

The router also always has 4G+ when its on 1.6.0 (i have manually selected band), the issue only arises when i upgrade it to 1.7.0
