I just wanted to check if there is any quick check I could do before I look to replace my HUB.
I have a powerline upstairs and my HUB downstairs.
Both obviously transmit WIFI

Recently I have been unable to connect to the WIFI coming from the HUB, but have no issues connecting to the Powerline signal.

They both come out the same Open-reach modem.
Am I rght in thinking the HUB is probably faulty, or is there some form of other checks I can run to ake sure I can it set up correctly. (It has been working fine previously)

Anyone?

Not sure what equipment your post is about ....'powerline' extenders use the house mains wiring and LAN cables, not wifi, or are you talking about a wifi extender ?
If it is a wifi extender, isnt the point that the wifi signal cannot reach where you want it and the wifi extender , as it's name suggests, extends the wifi signal to where it's needed, so you would expect not to be able to connect directly to the hub, if you could you wouldn't need the extender...

Thanks.
I have a BT Powerline WIFI Hotspot unit.
It runs my internet through the powerlines of the house as you mention.
The unit then has the ability to act as a WIFI extender or to plug a device straight into.
It has a different SSID to my main router.

Basically I can connect to the SSID from the powerline unit, but am having issues connecting with the main hub. I can be right next to the main HUB and not be able to connect to it, but can connect to the extender.
I need to try and understand if the SSID from the powerunit is interferring with the main HUB

Here is the unit I have

http://www.amazon.co.uk/BT-Wi-Fi-Hot...erline+Adapter

The SSID won't interfere with anything. All that is is the name by which the network announces itself to the world.

However if both WiFi units are transmitting on the same channel then they can interfere with each other. Though it would be very odd if the remote powerline unit was causing enough interference to swamp the hub WiFi when you are right next to the hub.

Are you 100% certain that you are trying to connect to the right hub? Where I live I can see half a dozen or so BT hub wifi signals all with very similar looking names. So always possible you are in fact trying to attach to a neighbour's WiFi network not your own. So just double check the SSID of the hub - both on the label attached to the hub and by going into the settings on the hub, as the label and the hub settings can differ.

Also double check the security password for the hub wifi. All too easy to confuse a lower case L with an upper case I for example. Simple errors like that will cause a connection failure.

Thanks for the response.
Yes, both passwords are correct and they are the right networks.
They work OK for 75% of the time, but for the other 25% it seems the main hub network is unable to connect.
Im certain its a fault with the HUB but wanted to check there isn't a chance they can interfere with each others unique signal first. I might change the channel on one to see if that resolves anything.

Thanks for the help and advice

As I posted it would be unusual for a remote WiFi signal even on the same channel to blatt out a local signal so badly you couldn't connect to it. Not unless the remote signal is so strong and/or the local signal is so weak that the relative signal strengths are similar.

It would be worth checking what channels the two WiFi networks are on and separate them if possible. Due to the way WiFi works you need to set them about 4 channel numbers apart to avoid mutual interference.

I would get rid of the powerline part and concentrate on the wi-fi. Powerline is bad technology which causes interference to other users as mains cabling is not designed to carry data.

Try running the HUB with just the HUB and nothing else ,apart from the phone line and power connected obviously, and see if you have the same problem .

i had a problem almost the same with the bt powerliners, i took both of them out and plugged them into a kitchen twin wall socket pressed the set button several times on both and after about 30 seconds it reset itself and the lights were in unison, i reconnected with the cables and never had a problem since, i think as the guys before have said they can be unstable sometimes but this worked for me.
