Hi there,

 

Every few days (at random it seems) our internet slows to a crawl or stops. Rebooting temporarily fixes it but sometimes it takes several reboots to fix.

 

When I look at the logs, I see various QMI errors - see attached. Does anyone know what these errors are and how to fix?

 

Also, it looks like the date on the modem is wrong (2018 instead of 2023) could this be causing an issue as well?

 

Any help would be much appreciated.

 

Cheers, Ben

OP here,

 

Sorry, I’ve just checked the time settings and they’re correct so the errors from 2018 aren’t current. Sorry for the confusion.

 

When I look at the logs for today, I don’t see any errors - see attached. Does any[one know what might be causing the random issues?

Hi, when the problem happens, is there any change on the LED status? such as signal bars reducing or even internet led turning off?

 

Please share with us screenshots of Advanced->Status page when internet works fine and also when internet stops working for comparison. Then send us the whole system log file after internet stops (please don't restart the router before saving the logs, or the previous logs will be cleared)

 

By the way, it is normal that the time of those QMI errors you mentioned shows 2018, they are actually not happening really in 2018, but some log records before the router connects to the internet every time when you reboot the router. Due to no internet yet, the time is not synchronized correctly, thus those logs show wrong date and time.

@Sunshine Thank you, that all makes sense.

 

I'll do as you ask while working tomorrow and report back.

 

Thank you again, very much appreciated.

  @Sunshine Still waiting for the slow-down but one thing I noticed is that when the problem occurred, even connecting to the router admin was slow - 5mins to load the login page and it didnt load any css styling. Then after the reboot yesterday, the admin loaded instantly.

 

So if loading a page directly from the router is slow (not from the internet) that probably indicates a WiFi issue - right? If so, is there anything I could check for the WiFi?
 

The router is only about 120cm from our POS iPads and we always see full strength on the iPads and router when it happens.

  @Sunshine Hi there, so it's happened again but I'm unable to take any screenshots because the router won't allow me to login, nothing loads - local admin or internet pages.

 

The only way to fix this is to pull the plug. There are no status light changes, everything looks normal.
 

So because I can't login to the router, does this indicate a wifi issue as opposed to an internet issue?
 

Another reason it might be wifi is that we have a POS printer connected to the router via Ethernet and when it can't see the router, it prints a 'No Network' error every minute until it reconnects. But when the router stops working (before turning off) the printer doesn't print this error, indicating the router is still functioning via ethernet but not via wifi?

 

The problem is that we do pop-up shops in different towns so I can't report back regularly but this issue has occured regularly for 2-3 years with two different mobile internet providers - so I'm fairly sure it's the router (and now suspect a wifi issue, not ISP) but any help advice welcome.

 

Cheers, Ben
