Intermittent WiFi dropout

[Bailey22]

I have recently experienced a problem with intermittent WiFi dropout that is becoming more frequent. When this happens and I interrogate any of my devices I get a message that says (words to the effect of) 'You are connected to the internet but there is no signal. Contact your Internet Service Provider'.

When the dropout occurs, the light on the front of the Huawei DG8041W-2.T5 router is rapidly flickering between red and white. Turning off the router and waiting 5 minutes before turning it back on clears the issue - until the next time!

Do I have a faulty router?

Hi Bailey22

The line test is clear - No faults detected.

Would you like me to send a replacement router for testing first to rule out any faults with your current router?

Thanks

Which master socket do you have then, please can you include a photo of it?

[Bailey22]

Thank you for your reply. 

I do not have the type of master socket that you have described, but I have fitted a different microfilter and replaced the cable that connects it to the router. Time will tell if it makes any difference. 

Thank you for your help and advice.

Then you probably have an unstable connection caused either by a faulty router or your broadband/fibre. What happens if you temporarily connect the router via a new or known working microfilter to the test socket? This is the one that is located behind the removable faceplate on the master socket (assuming that you have that design).

Thank you for your reply. 

No, I can't see anything like that.

If you look in the user log in the router:-

Dashboard > See Internet Settings > Manage advanced settings > Advance Configuration > Maintenance Diagnostics > User Log

Are there any entries at these like this:-

restarted due to kernel panic

If so, the router needs upgrading to firmware V1.06.
