Today my RUTX50 downloaded new modem firmware. Now my 5g connection is terrible and the connection is constantly dropping. Is there a way to go back to the preview modem version please?
Current version that installed today is RG501QEUAAR12A11M4G_04.200.04.200
I can see my mobile data traffic is almost zero right after the time the update happened and now almost all traffic is routing down the WAN interface.
Hi, what RUTOS version are you using?
RUTX_R_00.07.08
Also says RUTX_R_00.07.08.1 is available, but no matter how many times I try it will not install.
Also getting dreadful internet speed - wish I hadn’t installed the modem update now!
Maybe you remember which module firmware was before the update?
Sadly not.
Maybe you have some logs or troubleshoot file before the update?
Mine has RG501QEUAAR12A08M4G_04.200.04.200
Same here: RG501QEUAAR12A08M4G_04.200.04.200
Update went from 08 to 11.
Hmmm it seems that earlier versions of the modem firmware (07) had issues with the N28 band, which is what I’m using. I wonder if that issue has crept back into v11.
Which log would you recommend?
I’m now also getting a reoccurrence of the ‘Mobile ESM reject cause: Multiple PDN connections for a given APN not allowed’ message that I got when I first go the router but which was fixed a few RUTOS versions ago.
So you are getting same errror now? Take a look if there are more than one mobile interface for same SIM card in WAN page.
Also, you said that WAN cable is inserted, if you did the update, all your traffic now going through WAN, because module became unreachable doing update. Maybe you can try to unplug WAN and check the behaviour?
What’s happening?
What’s happening now?
My device park is perfectly fine, with “same here” I meant modem firmware
RG501QEUAAR12A08 M4G_04.200.04.200
Not touching it at the moment.
Do you mean that you updated from A08 to A11 and module is working correctly?
Sorry, i called it a night yesterday. This morning it is the same. Disconnecting from 5g every 30 seconds or so, basically the 5g is unusable as it is so unstable.
I really need to know if it is possible to return to the ‘08’ modem firmware version and where can i get it from please.
Nohhoo 
I said “same software version here” - not more than that.
And reading about those issues here, I will definitively stay on 08.
Not having a single 11 at this moment.
Any way to contact you in person? Want to inspect the device and see what is happening.
So I suppose you did the update
