Huawei B525 - Voice Calls

Hi

I have just bought the Huawei B525 router to replace my landline and home broadband. All is going fine using a Smarty unlimited data sim with calls and texts. I have managed to connect my landline phone and can make and receive calls (after deactivating answer phone). Issue I have is that when the phone rings, or I make a call using the router, my internet speed drops from 60mbps to around 12mbps. I understand this to be because the phone uses 3G and not 4G - which is fine - however, it takes up to an hour after ending the call, before the speed gets back up to what it was! Is this normal, or do I need to do a bit of tinkering with the settings.

Many thanks

Not sure what settings you could tinker with that would help with this issue, I've seen reports from some owners where they haven't been so lucky and its stayed on 3G until its manually forced back to 4G.

You don't say how you are connecting the phone to the router. I had all manner of problems when connecting via the RJ11 port on the router. Whilst the phone worked in a very basic fashion, it lost all its functions. I switched to using an ATA adapter (Granstream HT801 in my case) and everything has been fine. I was not aware that the phone used 3G. I have my router set to LTE only to prevent it dropping down to 3G and this seems to work OK.

By the sounds of it you're using VOIP (via an external ATA) and the OP is using the mobile sim in the router (via RJ11/45 on back) for incoming/outgoing calls

I get the same issue and it�s even worse when using 4G+ as the device will not take incoming calls whilst activated.

What might be happening is that the B525 is going back to 4G on band 20, later returning to band 3. Best thing to do is login to router and watch what happens when you make a call. It should drop to 3G and then return to 4G. If it�s not returning to 4G then try and router reset. If it is returning to 4G check to see what cell site ID it�s connected to. When it then speeds up check again to see if the cell ID has changed. If it has it�s likely the band 20 vs band 3 issue. To get around this problem you can lockout band 20 using a program like LTEinspectuer.

If it�s going to 4G+ when the device speeds up be aware you won�t be able to receive calls, and for this reason I no longer use the phone element as the speed is more important to me then having the device either needing manually forcing or locking to band 3 only.

Point taken. You can use the RJ11/45 port in the router in two ways. If you merely connect a phone to it, it will use the SIM card in the router and connect over the normal 3/4G network. However it is possible to configure the 525 to use the phone connected to the RJ11/45 port as a VOIP phone. I use Sipgate and the settings may be found at https://app.sipgatebasic.de/konfiguration/300/huawei... These settings apply to the router section on the B525 configuration settings. They are very easy to follow even if they are ib German. Still come back to what I said earlier, namely I found it better to use an external ATA adapter.

I have gone into the settings and the router is showing 4G and the Cell ID is 2946887. When I make a call, it shows the connection to be 3G with a cell ID of 6882835. When I disconnect the call, it goes straight back to 4G with the cell ID 2946824 and a slower internet speed.

That's good to know and thanks for the extra info

Sound�s like is returning to a band 20 cell. If you go to cellmapper.net and search your location and see if you can locate the cell ids you have listed. This will confirm if it�s a band 20 to band 3 issue. The hour gap makes me think it is.
