Since a thunderstorm yesterday, my network is not working (it claims to be up, but it isn't, after /etc/rc.d/rc.inet1 and /etc/rc.d/rc.inet2. netstat -a shows eth0 and wlan0 as appearing to be up. I can't even ping the router.

I remember there being single mode for booting in to do physical system diagnostics, but not how to get there if that's even what I need to do. I'm using my tablet right now. Help please....

Thanks

Using your tablet would mean the router is functional.
Is your system a laptop or desktop?
Is your system using wired or wireless?
If wired does the output of the ethtool for eth0 show a link at the correct speed?
If wired are the link lights illuminated at both ends?
I assume both devices show via lspci or lsusb?
Does the output of dmesg show any errors pertaining to either device?
If wireless can it detect the router's ssid?

I forgot to mention that here. Yes, the router is functional. I have wired and wifi for my laptop.

There arr no link lights but that's normal.

Select from dmesg:

Whew...that's a lot to type (I did obviously combine the iwlefi lines into one).

And finally, wireless isn't, as far as I know, detecting anything.

Thanks

Sorry, all that 'stuff' you went thru the effort of typing in, isn't useful. Just a couple of key basic info is needed.

Try powering-off both the PC (& router).
(IF the wifi actuallly has a [link layer 2 vs. IP layer 3] connection 'UP' with the SSID,
my next guess is that [IDK why] the router refuses to give a DHCP to the PC!)


Probably continue in that prior thread.

No help... Is there a way in Slackware to do a hardware diagnosis for the network interfaces? More and more I'm thinking that the lightning, via mutual induction, damaged them. I want to either prove or, preferably, rule that out.

Thanks

Maybe iwconfig; iw list
(I'm not sure what tiny bit might be relevant and I don't mean for you to type in the tons of output it might give!)

Even: sudo iw dev whateverYOURSis scan
Will output hundreds of lines for every router it sees!

I don't use sudo. I've been around Unix in various forms to know NEVER to use root unless I (as wheel or whatever the non-BSD4.2 side calls it) can't.

Anyways, I posted it above.

Thanks
