ALL wifi enabled devices dropping and very slow but Broadband is ok.

[HARLEYCOL]

Recently, all of my Wifi enabled equipment is dropping and is unable to reconnect.  3 x Alexa Show5 display Signal Strength " Excellent"  but settings link speed of only 1Mbps .  5 x Echo Dot 3's and 4 are unable to connect.  When they do manage to connect the response to any command takes a long time or I get  "I'm having trouble connecting".

I reset the router to default and reset every device to reconnect the network then after a day or so the same occurs. 

I have 5Ghz switched off due to my Alexa's and light switches being 2.4Ghz

My phone (Samsung 23) often shows connected with no internet.  .  When my phone is connected it shows a speed of 104Mbps even though it is connected to 2.4Ghz. 

When all of this is happening, my ethernet connected PC & Laptop remain at 145Mbps.  No dropouts or loss of speed. 

BT sent me a new router which was good for a day then the same happened.  Even when standing 1 metre away from the router the phone often connect but has no internet.     Tried selecting different channels other than 11 which seems to be the standard. 

A wifi analyser app shows a strong signal even at the end of my garden were I have another Echo dot 4 for music in the gazebo.

I'm baffled by what is happening...  Any advise or assistance appreciated.

the Alexa show 5 is quite capable of connecting to 5ghz so maybe turn on again

did you try the wifi analyser to see what channels are in use near you then select the least congested both for 2.4/5ghz

you could also try changing wifi mode from 1 to either 2 or 3

Thanks for the prompt response . I may have cracked it...  I looked and some router logs that I periodically save and spotted that this started when I mounted a bird box camera on the house wall.  The camera is Wifi but does not connect to my Wifi.  It is a small camera connecting to its own receiver that connects to a monitor via HDMI.  It has a choice of 4 channels at 2.414,  2.432,  2.450 or 2.468Ghz.  I had the the 2.450 selected.   I disconnected the bird box camera receiver and everything is connecting now at a good speed.    Not sure if this is coincidental or if the camera receiver is interfering with my Wifi.  If it is, the camera works better as a wifi blocker than a camera to be honest 🙂   

I'll leave it off for a week ( even though the Blue **bleep** in the box are about to lay eggs ) and update the forum if it is the bird box camera.  I'll probably need to get in touch with Green Feathers, the company that sell these camera's to see what they have as a solution.  

BTW:  I know that the SHOWs are 5Ghz capable but if I have 5Ghz enabled, my other devices that are not dual channel, don't respond to the Show's that are on 5Ghz.  I read somewhere that this was a common problem on BT routers and they were looking at resolving it with a FW update.  Speed on WiFi is good enough on 2.4Ghz and I need the distance it provides for the garden Echo Dot.

you appear to have solved your own problem

I will leave it unresolved for now until a few days of wifi stability have passed.
