New three 5g Hub Zyxel NR5103E

[Casper1972]

Hi, new to three 5g Mobile broadband. I have just received my 5g hub  Zyxel NR5103E router. Whilst I find the speeds and coverage very good where I live, I find that through the day I lose connectivity until I reboot the hub. After searching many threads on the community, I found this to be common. 

Is there any news on the new firmware release and will this fix this issue. Currently on V1.00) ACBJ.0) b12 firmware.

I did see a thread from 3 (firmware update in the testing phases for the Zyxel NR5103E router)

I have contacted three dedicated broadband and they have performed tests etc and say there is no problem, yet today my hub has dropped out 3 times and I have had to restart the hub each time.

I am trialling this for 30 days but if this does not improve then I will have to look elsewhere for better service. It's a shame because the speeds are good, and I have a very good 5g signal.

Hello @JonathanB 

I am having some troubles with my 5g Broadband with downloading and upload speed on a PlayStation 5 console and all my devices. I have run an internet speed test on the device and I see that the download speed is around 20+ Mbps but the upload speed seems restricted. There is an error message appearing on the screen saying that the router does not support IP packet fragmentation and to contact my service provider for help.

I’m currently using wired Connection, I tried both Wi-Fi and Wired but both the same, my 5g Broadband is Currently placed by the window, signal is Excellent.

When I first received the router, I was getting over 300Mbps but now getting 20-50Mbps,

Gaming is Unplayable, very laggy every time I tried to play a game either on my computer or Console it will just completely disconnect from the game, am now unable to play any games

And now since yesterday, if trying to download something or games on The PS5 , the broadband disconnects. I have to turn it off and back on again.

I’ve tried to move it around to see where I get better signal but made no difference

Hey @Casper1972,

Any update on your issue following the tests with band locking?

Cheers

Hi, band locking didn't work, spoke to broadband technician and they said I have a faulty hub, awaiting a replacement hub.

Glad to hear you got the replacement sorted easily enough!

Hi @Casper1972 

I myself have had the issue with losing connectivity a few times but its only happened a few times for me luckily.

When it happens the router admin page and router LEDs appears to show the connection is fine, good signal etc but just no connectivity until rebooted.

I have reported this issue to @JonathanB via PM so hopefully he can take note that you are also experiencing it and pass the info on for firmware investigation.

b12 is currently the latest firmware.

If you log into the router admin panel and go onto the cellular stats page what CELL ID and Bands is your NR5103E connecting to?

Can you also post a screenshot of your cellular stats so I can get an idea of the signal quality, noise etc?

[Casper1972]

Hi 

CELL ID is 12980481

Band  B3,B1,n78,n78.

Unable to screenshot at the moment.

Thanks for the info, just checked out the mast that you are connected to and looks like it provides the following bands:

1,3,20,28,n78

Atm you are connected to B3, B1 with a double connection to N78 (which is the 5G band).

The NR5103E supports band locking via the router admin portal so might be worth trying to lock against some specific band combinations to see if there's any improvement in speed and stability, maybe try lock to these combos and test speeds and stability of each:

B28+N78

B3+B28+N78

B1+B28+N78

B1+B3+B28+N78

Hi 

Just tried logging into the admin settings but could not find where to lock bands.

Many thanks

I have changed the settings, so will see how it goes.

After speaking to dedicated broadband team they have said if my signal drops again in the next 24hrs to contact them and they will look at replacing the Hub??
