Ethernet problem
« on: October 10, 2012, 01:34:15 AM »
Not sure if this should be here or in Hardware, or Network, or what, so sorry if I'm wrong.  Machine specs:
Mobo is Gigabyte P45T-ES3GCPU Intel E8400 @ 3.00 GHz Mem: 8GiB From lshw:

Problem:  This machine dual-boots Win7-64 and PCLOS-64, and is more often used on Windows.  (I have a separate machine for Linux.)  Problem first manifested
in Windows, shortly after a storm which had lightning, but not close, AFAICT.  Had trouble connecting to internet or to printers. (One printer, an old LaserJet, is
setup thru a Trendnet print server to convert Ethernet into USB.) Printers are networked thru router to cable modem.  After some futzing around, and (in Windows)
manually putting in TCP/IPv4 Properties IP address 192.168.1.105, subnet mask 255.255.255.0, Default gateway 192.168.1.1 preferred DNS server 8.8.8.8 and Alternate
DNS server 8.8.4.4, and also telling the print setup that the printer was at address 192.168.1.5 (static ip of print server) Windows worked. I wanted to put in a
wireless N 8-port  wireless router, at this point, a D-Link DIR-632. I could not get the computer to log in to this router, and I finally installed the router from XP
on another machine without a problem. That other machine has PCLOS 32-bit, and I reset the printer stuff in Linux, and everything works from there.
So I rebooted the first machine into PCLOS-64.  It can see the internet, and I'm writing this on that machine,but it refuses to see the printers at all. 
I am wondering if there is a fault in the Ethernet circuit on the mobo, and how to test it. Perhaps not completely blown, but damaged. Also, I have an HP
10/100 Ethernet card, and plenty of PCI slots that I could use to plug it in.  If I do that, how do I get Windows and PCLOS to recognize it and use it?
instead of the mobo port?  (I need Windows for a couple of programs--AutoCAD and WordPerfect, primarily.)
Sorry for such a long post, but I tried to answer the questions that I could anticipate.
(JUst to make things interesting, just as I was about to send this, the cable went out! It's back now, and I sneaker-netted this file over to my normal Linux machine.)
All help greatly appreciated. What do you folks suggest?

I suggest you try a liveCD/DVD of PCLOS 32 bit on the machine.

Problems with 64 bit test ISO are not supported on the forum.

If the same problems manifest themselves in the 32 bit liveCD/DVD then you will have a better chance of success in determining if the problem is hardware or software.

I only have the 64-bit version installed as a sandbox, but I thought I remembered that the printers worked.  Anyway, I booted the machine on the Live CD, 2012.2, and everything works fine--the Internet,
the two main printers, even a printer on this Linux machine connected to its USB port!  All of them found and initialized without me having to do anything!  So I guess it's a Windows problem. Do any of  you
readers have a favorite list or forum to direct me to for Windows assistance?

Thanx for the excellent idea of booting off a Live CD to test it out.  I don't think I realized how complete the operation would be from a live system!
PCLOS-wise, I have to say SOLVED--even tho the 64-bit version is unhappy.  Any idea when the 64-bit version will be finalized?

I'm glad you have been able to narrow does the cause/s of your problems  ;)

There is no release time/date ever given for a PCLOS release, so anything said along those lines is guesswork and/or speculation.

'When its ready' is the only available answer  ;)

Sorry ....  I have no Windows info for you
