Hi all,

I have my ADSL connection via a modem/router using ethernet cables. My mobo
is an old GA-7VT600 1394 running an Athlon XP 2800+. All has been working
fine for years, but just last week I have lost all the lights on the Realtek
NIC and my connection to the net..... Does lights out on the onboard NIC
mean it's dead? I haven't flashed the bios or done anything silly to the
system. Win XP just says that the cable in 'unplugged'. I have tried 3
other cables and nothing - still no lights. The LAN is enabled in the bios
OK as it has been working for literally years...... Does this mean I will
have to put in a PCI NIC card?

Thank you.

The mobo manual should mention the "status" lights for the on-board NIC. If you
don't have the manual you should be able to download one. That would be my own
first line of investigation

Probably. RTFM.

Realtek (http://www.realtek.com.tw) have DOS based diagnostic
utilities (eg rset81xx) for their RTL81xx Ethernet chips. There might
even be one in your driver package.

Yeah, I'm afraid so, the NICs give out eventually after several years. I
had an onboard NIC in my ECS K7S5A board (which I'm still using now),
and it gave out about 4 years ago. Been using a PCI NIC ever since then.
They're pretty cheap, about $20.

processor on board and it will offload a lot of work from the CPU. I am
running a 3Com 3CR990 on a cable modem setup that runs up to 13Mbps
until they throttle me back to 7.5Mbps and the processor load remains
low. With a cheap card like the 3C905 the CPU has to do a lot more work.
The on board stuff tends to be the cheapest that the MB manufacturer can
find and is not usually that great. My MB is an ASUS K8N and both the
network port and the on board audio are jokes, even though ASUS is one
of the better MB companies.
E-bay might be the best way to find a NIC card as long as you get the
setup CD or can download it.
Best of luck.

Probably not terribly important but it does mean less work for any
security software you might have. I suppose I am overdoing it by also
going through a Cisco/Linksys WRT54G router and it's internal
fire-walling, but it does work with both XP and all the flavors of Linux
I have tried.
XP. Every comment I have seen posted says that Vista flat out sucks.
Until I am forced to commit a hard drive to it, there will be no Vista here.

Are you using the above security features on your machine?
I did the setup under XP SP2+(a bunch of MS patches) and it works under
Linux. 3Com seems to have mostly dropped the NIC card business unless
you want to get into the hundreds of dollars. Now that the MB vendors
have put ethernet on the boards people seem to forget that a separate
and dedicated NIC co-processor really did help. My comment on cheap junk
on the MBs holds. My audio is Realtek and it is junk, hence a sound blaster.
That's all I can add.

I don't know much about networking, but it seems to me that the extra
processing capability of 3Com's 3CR990 NIC is tied up with security
related tasks. Just how important are the following "offloads" for the
typical home user?

http://www.3com.com/products/en_US/d...u=3CR990-TX-97

Security offloads: 168-bit 3DES, 56-bit DES, SHA-1, MD5, RFC 2402
Additional offloads: TCP segmentation, TCP large send, TCP/IP checksum

I notice from your headers that you are using "Windows/20070221". Is
this Vista? Are you using the above security features on your machine?
If so, did Vista come with built-in support for your card? I notice
that 3Com's web site only provides W2K and XP support for the
discontinued 3CR990.

Your original statement that typical NICs have no onboard CPU had me
wondering whether my Realtek cheapie was some kind of "win-NIC". Now
you appear to be saying that NICs *do* in fact have their own CPU, but
that the more expensive ones have an additional co-processor to
support non-standard features such as hardware based security. If
that's the case, then it seems to me that you are bagging a Volkswagen
for not being a Porsche.

AFAICT, a typical NIC that sells for about $10-15 has the exact same
hardware as what is on a motherboard (other than a boot ROM socket).

No Duh, Ralph.
That's why I was hinting at not using the el-cheapo or whatever crap
they put in there and choose your NIC, same as a sound card or video.

Remember that ***ANY*** load your CPU doesn't have to process makes more
cycles available to you for your chosen program.

Of course not, but it begs the question, just how much does the
co-processor contribute to overall throughput?

Well, for $30 I can buy a DVD player with a PSU, case, VFD, DVD
loader, RAM, flash EEPROM, remote control, etc, etc. Within that
package is an MPEG4 capable decoder chip which probably has ten times
the processing power of a $10 NIC. So no, I wouldn't be surprised to
find that I could buy a Gigabit NIC for around $10.

True, but whether this results in a significant reduction in CPU load
is something you need to test for yourself.

Regardless, it seems to me that motherboard chipsets have come a long
way since last time you (or I) looked. Having said that, your
motherboard may be bottlenecked by a 100Mbps PHY.
