For diagnostic purposes (to rule in/out hardware) it might be worth booting a LiveCD/LiveUSB and seeing if the ethernet cable/port works ?

Funny you should say that Mark cos I've just done that with a live USB - different distro tho - Miyolinux (Devuan/openbox based) lightweight & systemd free (that was my interest). It uses wcid & wouldn't connect but I don't know if it is properly configured so going to put pepp 7 on the stick because I know its ok  ;)

Yes a different Cat5 cable would indeed be good - but it won't be tonight  ;D

In the meantime:

Code: [Select]
mick@mick-Inspiron-1501 ~ $ sudo mii-tool -v eth0
[sudo] password for mick:
eth0: no link
  product info: vendor 00:10:18, model 54 rev 0
  basic mode:   autonegotiation enabled
  basic status: no link
  capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control

Code: [Select]
mick@mick-Inspiron-1501 ~ $ sudo mii-tool -R eth0
resetting the transceiver...

Code: [Select]
mick@mick-Inspiron-1501 ~ $ sudo mii-tool -v eth0
eth0: no link
  product info: vendor 00:10:18, model 54 rev 0
  basic mode:   autonegotiation enabled
  basic status: no link
  capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control

And Good evening Mac - thanks for the suggestion - I will take a look but as I said in my OP I did originally connect through the router via the Cat5 cable  :-\

Gonna sort this Live USB now  ;)

If it works from the liveUSB, can you install ethtool and post the output from
Code: [Select]
sudo ethtool eth0
So we can see what's different (if anything).

Well tried Ethernet connection with Pepp7 live USB & no joy  - what I find difficult to understand & accept is the fact that i have successfully connected already & now I can't  ???
 If you're fairly confident it's not a software/configuration issue then the logical thing is to get another Cat5 cable & test again with that. I will have a look at the Router config again too - an other ideas Mark before I, & probably you, knock off for the night  :)

Not really .. it looks like it's either a hardware problem (cable or network card)

or a config issue in ether the router or BIOS

Have you another PC you could test the cable with ?
(though even that might not be a 100% accurate test .. the other PC might be able to auto negotiate a link with that length of cable where this one can't .. signals degrade with cable length and rf interferance)

Have you looked inside the ethernet port to see if any of the pins are bent ?

PS. If any of the pins look bent DO NOT try to bend them back with the PC switched on ;)
(if they touch whilst powered you could fry the adapter or worse the entire motherboard)

PPS. If you *do* decide to get another cable, maybe go for cat6 (preferably shielded)

Well had a look in the Ethernet point & all the pins are uniform in shape - I've also looked in the BIOS (which is very basic on this old Inspiron) & I am at the moment looking at the Router config but nothing obvious that I can see.

I'm afraid this Inspiron is all I've got & as I reiterated earlier I have had a connection already but a different, perhaps short cat5 cable is probably next up  ;)
Anyway "It's Good night from me..."  ;D

Roger that - cat6 cable ;)

Just a quick one before I go - is there anyway to test the ethernet adapter?

Not really without testing it with a known good cable.

Update:
Got good new 1m length cat5 cable however still the same & also no joy with live USB. Have reset router to default too.

So is there anyway that I can test the network card?

Are the modules/drivers loaded (think they are did modprobe b44 as per OP)?

 ???

Drivers must be loaded or you wouldn't be getting an "eth0" in ifconfig.

But you can check which drivers are currently loaded with
Code: [Select]
lsmod

Is this a laptop ?

Code: [Select]
mick@mick-Inspiron-1501 ~ $ dmesg | grep eth0 > ~/Desktop/dmesg.txt

Just gives me a blank file - does this mean that the interface isn't showing link becomes ready??

what's the output from
Code: [Select]
dmesg | grep -i b44

have you got IPv6 set to "Ignore" ?

Cheers for  getting back Mark - I can see you've been busy

Code: [Select]
mick@mick-Inspiron-1501 ~ $ dmesg | grep -i b44
mick@mick-Inspiron-1501 ~ $
Nothing

I've currently got IPv6 in my Wired connection 1 profile set to Automatic - although I have tried Ignore

I am also currently disconnected ethernet-wise but can connect  ;)

Okay that's odd  :-\

Can you run:
Code: [Select]
dmesg > ~/Desktop/dmesg.txt
then host the dmesg.txt file on your desktop online somewhere and PM me a link to it so I can take a look.
