Raspberrypi 2

Well after attempting to upgrade to the latest Rasbian resulted in
failure (baulked at the Wolfram data). With messages saying the
upgrade had failed or similar I copied the latest disc image to an sd
card and I am using that.
However despite installing wicd curses I have completely failed to get
into the internet or wlan.
I kept a copy of the original files from the pi B+ and have spent
hours trying various entries in network/interfaces and wpa_supplicant
and reading forums? and advice but nothing looks like working.
I have found nothing like the previous wifi-config which scanned for
the connection.
The advice on filling in the wicd panel left me quite confused and I
now see the point of the 'Best of Luck' comment.
The messages I get when clicking on 'network prefrences' is ETH0 link
is down/wlan0 is not associated.
Are there any other apps I need to install?
Is the Pi2 Rasbian different to the previous version in the wireless
department? different dongle required?
Can anyone point me at any more advice on the latest rasbian/Pi2.
At least I have now got the 2.9 version of Sonic Pi, and I can get on
the internet with the cable

PS sorry for the long ramble

Never mind all this graphical nonsense that hides scary things from you. Get yourself a root shell, then this stuff can be fixed.
ifconfig wlan0
will either give "error fetching interface information: Device not found" or some information on what the wireless network interface thinks it's doing. If you get the latter, you're fine on the driver front. (There's very little difference between Linux versions in terms of required drivers - this isn't Windows.)
If you have a viable wlan0 you can use the technique from a blog post I wrote last year:

(I think the Pi prefers /etc/wpa/wpa_supplicant.conf rather than the /etc/wpa_supplicant.conf that I used there.)

Well I have tried that without any success. Two things, there is already quite a few entries in wpa_supplicant.conf which may be muddying the water and if I try 'ip addr' the message 'NO CARRIER BROADCAST' occurs for both eth0 and wlan0. I am supposed to be using a static address but no address is shown

You could try the latest OS - Jessie. I never could get the graphical setup for Wi-Fi to work on Wheezy, but trying with an RPi 2 and Jessie the graphical setup worked straight away.

I am using Jessie and having no success establishing a wireless connection to the internet. Are there any checks I could carry out to see if there is a problem with the board. The donngle works OK on a Pi B+

Wow! Thunderbird really screwed this one up. I'm having trouble with my Internet connection and Tbird put a message from another group into this group (sci.electronics.design). But notice the subject line is from the thread in sci.electronics.design and does not match the message from comp.sys.raspberry-pi. Then on top of that it attributed the message to the person in this group.
WTF!

Just accept it. Computers hate you.
If it makes you feel any better they hate me too :(

I have also found that iwconfig is a good tool to use diagnosing recalcitrant wifi hardware.

Which Dongle? There were some notes to the effect that some don't work! I've even had this problem with Win 7 and run of the mill PCs!

Both my dongles are Tenda, with no other markings

That's the USB hub and wired ethernet controller and not a Wifi dongle.

How about :- Ralink technology RT5370 Wireless adaptor. It is shown as installed but it does not appear to be working.
Can anyone give me a type that does work with Pi2

The RT5370 works fine. It's your setup that is wrong.
Start again with a fresh Raspbian Jessie install with nothing from before.
Plug in the ethernet and check that works. Update and upgrade to get the latest fixes installed from the repos. Check you have the Ralink irmware in case it is not included in Jessie by default.
At this point Wifi should be working but not connecting to anything. Then follow this guide:

At this point you should have basic Wifi.

Thankyou MM. I followed your instructions to the letter and the final outcome was as you said. Not sure where I had gone wrong earlier. I was even using the same Modmypi script. Now I can mmove on. Thanks again

That almost sounds like a MCSE solution. :-\
