HELP My router has gone bananas

[macgd016]

I'm not even sure how to describe the problem as there seem to be multiple ones.  The latest came about when trying to resolve another one so excuse my muddled description.

This morning my weather station stopped communicating to the router Fast5364. Fault finding shows that when attempting a new connection it finds the router and passes the password test but does not connect.  My final throw of the dice was to switch the router and power line off. That didn't resolve the issue but my desktop then no longer connected to the router.

All my phones & tablets still connect both to my router & power line but the PC won't connect via ether.  I have 2.4ghz & 5 ghz as well as ethernet but the PC won't connect via any of them.  However, by chance I found it will connect on the Guest SSDI

Something else I observed is that looking at the connected devices on the router, very few are mentioned and one phone is shown connected to the ethernet

I'd like to avoid doing a general reset as I don't have much time but if there is a quick way of sorting this PLEASE tell me

Hi there @KeithFrench thank you for the support.

[KeithFrench]

Glad that you have it sorted.

Port forwarding is only required for connections originating from the internet to a locally connected device. It is not required for outgoing connections to the internet. However, some devices may require it if they make a connection to some server and that server needs to then create a second session back to the device for the service to work. Not having a Heatmiser myself, I have no idea how the service works.

Thanks Keith for your help.  

I think I've found the problem but not through skill just elimination. 

I thought it was a powerline problem but it turns out it is my Heatmiser network adaptor.  Everything works as it should until I plug the ethernet cable into the powerline next to it and it doesn't matter which powerline I plug in there.  Cable disconnected no problems, plugged in all sorts if issues 

Resolving it will have to wait for another day though

Hi Keith

Many thanks for this and I will go through it when time allows, however, I have a partial fix and hope you can help me with the rest

I went back to basics and switched everything off and then on in sequence.

Router on & PC & all mobiles connect to any wifi.  Weather Station on and it connected.  Ethernet Power Link & Heatmiser - no connection.  TP-Link wifi and everything back to square one.

I'm not worried about the TP-Link wifi so switched off all the Power Link again and wifi from router resumed for PC.  I would like to get the Heatmiser running again so removed the Power Link by the router & replaced it with an old one I have.  They connect but I still can access the Heatmiser.  I would like to get this going is I can & I may have changed something in the router config thats stopping it.

I believe that I need to put some port forwarding in place, see attached.  But is there anything else

[KeithFrench]

If the TP-Link handles all WiFi connections in the house, the router is behaving as I would expect. This is due to the fact that all connections are over Ethernet as far as the router is concerned. I think that any device that cannot connect, can not connect to your TP-Link, not the router.

That said, I am more than happy to try and help you with this. Have you rebooted the TP-Link?

Hi @macgd016 

The next thing is to start investigating why this is an issue. Wi-Fi interference (nothing to do with electrical interference) can cause:-

1. Slow speed,
2. intermittent dropouts,
3. breaks in the signal,
4. no signal at all,
5. or no internet access.

This can affect one or more devices. This can also lead to a permanent reduction in the speed of one or more devices. No ISP can be responsible for your local environment; this is mainly a byproduct of the popularity of Wi-Fi.

Generally speaking, the 2.4GHz band suffers far more from Wi-Fi interference than the much faster 5GHz band. However, the 2.4GHz band has a longer range than the 5GHz band and can penetrate walls better. This may very well change depending on your local area.

In other words, I offer a free, impartial analysis of your Wi-Fi network and will try to help you optimise your Wi-Fi connection. The next stage involves my sending out a guide to help you get important diagnostic information for me. I will then analyse these results for you and recommend changes to your router configuration, if required.

I only send this out to people who request it.

Hi @macgd016 

What model number is this TP-Link, is it a straight forward power line extending the Ethernet, or does it extend the WiFi as well. I expect it is the latter.

What WiFi channel is the router using on the 5GHz band? If you go into the advanced settings and the 5GHz gear icon, it is in there. Please PM me (to protect your privacy) the screenshot of this. I will delete the other one, as it can be seen by anyone the world over.

Hi Keith

The power lines are tp-link

Further info, I did a factory reset by holding the reset button but it seems only to have done a partial reset. The user name and password stayed the same but it did remove my routing options.

End result though is nothing has changed, see screen shot which shows most of my WiFi devices are on the ethernet

Hi @macgd016 

There probably isn't a quick fix, because this could be caused by various issues, I am afraid. However, before I start trying to help you, what is the make & model of powerline adapter that you have?
