New router

Is the new router using the same subnet as the old one? (most are on

Are the W7 box, the RPi and anything else dependent on that router getting their IPs assigned by the same DHCP server? Are they all using the same WiFi encryption standard, etc.?

The routers have the same address - 192.168.1.254. The wifi network name and password key are different but I have changed to the new name and password in /etc/network/interfaces. I have had static settings on Pi and W7 throughout. Now the encription standard I am unsure about, though everything works on the internet OK.

Have you got the Pi set to static IP address? If so check that the IPs addresses used by the router haven't changed. It could be using a different subnet, which will stop anything seeing the Pi or vice versa. If using a different address on the same subnet, the default gateway on the Pi needs updating or it wont see the internet.

BTW: When I upgraded to fibre 6 months ago they were supplying the utterly s*it Thomson/Technicolor router, who's Wireless-N wouldn't do

cards in the laptops. The wireless is now interference free on 5GHz and will outpace fibre speeds for a good few years to come.

Importantly the configuration of the router is far easier, and I was able to set it up with all the same address details as my previous router, so I didn't have to alter the static addresses on my 3 Pi's.

I have looked at tthe router settings using 192.168.1.254 and it lists Devices connected to my router. The pi is listed at address

I found that the GUI was a waste of time here, and I've always configured from the command line with nano. Here's one link I found just now:

I have tried to edit and save wpa_suplicant.conf but failed. Even using sudo and root. It will not allow the file to be overwritten nor can I change a file name to that required. Can someone educate me please.

Managed to make the changes now but WiFi config still does not swing into action. Does not even show the dongle though on boot -up it does say that wifi is already configured.

Enough for tonight/ ggod night

If your Windows machine is pinging something but your rPi is not on the network then what is the Windows machine pinging instead of your rPi?

What happens from the Windows machine's point of view when you switch the rPi off?

Ian ping the Pi from the ARMX6 using 192.168.1.90 with no data loss. I can ping 192.168.1.90 from the W7 with no data loss if the Pi is online. With the Pi off line I get data loss. If I ping the W7 192.168.1.30 from the Pi I get data loss as I do pinging the ARMX6 (192.168.1.20). However the data loss is around 20%, not 100%. If I try to set up the WiFi Config app on the Pi it always fails with 'Failed to enable network in wpa_supplicant configuration' on pressing the 'add' key. My Nexus can see all the computers using Fing and ES file explorer.

Tricky one. Try running something computationally intensive on the Pi and ping it from one of the other computers to see if you get any packet loss in that direction then. If so the Pi may not be supplying sufficient power to drive the Wifi dongle unless it is idle.

Tried that by having a game running while pinging and got 7% to 10% packet loss. Tried different dongle with no difference.

My conclusion is the setup is wrong on the router or the Pi or both.

It used to work with the old router. So the Pi hardware works.

It works for W7.

It only doesn't work where you have had to change files or settings.

That tells you where the problem is.

I have changed the setting in /etc/network/interfaces to the new WiFi Network and password key, and that did not appear to work in as much as WiFi config contained no info. I then followed instructions on WiFi connection pointed to by Dave Taylor which involved entering data into etc/wpa_supplicant/wpa_supplicant.conf.

None of which as resulted in WiFi Config working as expected. If I enter the neccesary data into the network config panel and press 'ADD' I get the error 'failed to enable network in wpa_suplicant configuration. From this I assume I have something incorrectly set in one or both of the above files. If I knew what I would correct it. Before I went to the new fibre router I did not know about wpa_supplicant so it was using default settings.

The bits that no longer work are the bits you've edited. So that suggests the problems are related to those edits. When you review the data so far it all points to your edits.

Undo all the changes and start again. And do it carefully. You have "previous form" when it comes to SNAFUing edits on Python scripts so it may seem harsh to say but the problem is most likely going to be "fat fingers" on the latest edits.
