Difficult internet access

I just noticed a pop up. It said Bitdefender update has failed. Clearly nothing is getting access to the internet today.

Is your router set as Home Network?

50% is low and will get drops or Terry's you need 79+ ideally so with phone stand by router should be 100% then move towards PCs were does it drop is there a wall, TV,power cable were it drops that's doing it?. It may be a pain but one next to router does it work there ok if so it proves PC is fine something is blocking signal

Samuria, I agree that the signal is weak but one computer work and the other, just on the side, doesn't. It's something else.

That's why it needs to close to router as a test if it's ok it's signal if it's still had we have illuminated signal and then need to try other things

Yes, as in the image my router is shown as Home network.

UPDATE:
I have 4 bars up on the little desktop indicator and it seems to connect to the internet OK this morning. Anti V and two browsers have updated normally and I can get to websites but they are loading a little slowly. Chrome browser tries to update and fails or gets halfway through and sticks. Opera and Firefox are fine.

I tried the little phone app again. The readings are the same as in post #6 and right next to the router it reads -28db. The numbers slowly increase as I walk away and go into the next room toward the PCs.

One thing to add, one of the main causes of WiFi comms issue is the common or garden Cordless phone ...

The standard frequency used for cordless phones is 2.4GHz worldwide, the UK actually regulates for this to have UK phone systems use 1.88-1.9GHz, specifically to prevent interference with 2.4GHz WiFi.

With the worldwide technology business that we see with the likes of Amazon & Ebay, it is not unknown for a DECT Phone designed to run on 2.4GHz to find it's way onto the UK market, (a change of the connecting lead to the phone line and Mains is easy to do as both are usually replaceable by design), and cause issues for a WiFi Router placed close to the Phone Base station

It's often the case that a phone and WiFi Router end up on the same side table or shelf, worth checking if the phone is too close to the Router and if it is set to use 2.4 GHz (some are universal and have a switching mechanism for frequency).

May be nothing, but worth a check

OK and thanks for the input. My router and cordless phone base unit are side by side on the only convenient surface near the incoming phone line socket. Here's what we've got. The router as supplied by Orange (France) is made by Sagem, called the Livebox Play. The phone is a BT8600 call blocker, purchased on ebay (UK). If interference is a possible issue it will be difficult but not impossible to separate them.
