Now, another question... bandwidth...

I'm still a newbie. But I feel, since everyone's been having problems
with gateways that won't work, and they feel like my problem, I should
offer the solution that I found.

But, with that solution I've been presented with a new problem, one that
I really don't know if I can answer (although I'm looking, right now,
into the problem, and asking this question).

Bandwidth. I recently got a Verizon FiOS 5/2 link installed in my home.
It's alright, usually... but with the DLINK I did much better than
I'm doing now. I could get bursts of 500KB/s or more, usually rounding
out to about 300. Now, using the Linux box, I get at most 100 KB...

So, obviously I'm still not quite there... wondering if anyone has
experienced this one and can offer an answer.

I'm using the DLINK as a hub, because it's 10/100, and not just 10 like
the little hub I was using before. It works fine as long as the
internal network uses static IPs in the 192.168.1.x range, and not
192.168.0.x like the DLINK assigns.

Just wondering. I'm about to make sure both of these cards are 100
megabit, but I don't know why it would matter because the maximum
combined bandwidth the internet would take is 7 megabits.

You are aware of the differences between hubs/routers/switches? Are you
sure hub is the term you want to use?

broadband routers are not very fast usually. check the stats or
something to tell you how much you can pass through that thing. I would
expect a full computer to be much faster.

I know the difference between a hub and a router.

The problem here is I have a little LinkSys 10 megabit hub, and a DLINK
100 mb router. When I run straight off the router, without the Linux box
involved, it's rather quick compared to now.

Now, both of my linux cards are 100 Mb, one goes up to the PPPoE link,
the other out to which ever I am using, the hub or the router... and either
one of them, the result after putting it behind Linux is the same, a marked
decrease in speeds at the other systems.

Surfing the web on the Linux box is fine, though. I didn't have this
problem with the 2.20 kernel box I was running.

I'm thinking somewhere in the kernel is some pre-programmed bandwidth
limitation to each PC. I was hoping someone could help me with that.

Also, something about FiOS, my internet went down this afternoon, and I
had to power-off the system and run the pppoeconf again, it still couldn't
find the access concentrator. Only after I unplugged the network, plugged
it into the router, and then plugged it back into eth0 and reboot did it
find the access concentrator.

Any help on that is also appreciated.

Check your NIC drivers. For instance, NVIDIA drivers have 2 modes, CPU
or throughput. CPU reduces throughput so that you can use the computer
and the GUI and sound are still smooth. Throughput mode will tax the
CPU and give the local linux user a choppy experience, but increase the
data flow rate through the box.

I switched the cards around, I made eth1 the inbound from the FiOS
connection (the 8139 card), and then I took the 8029 card and hooked it up
to a 10 Megabit hub, and all worked fine. I got complete speed and
throughput back on all of my PCs, in fact, speed improved even on the
gateway PC.

Who would have thunk that solution? I just want to know why.

8139 is 100Mbps, 8029 is 10Mbps :-p

Hmm. I thought so. Now things should be okay. Thanks Grant.

It is very unlikley that the speed on the link between your PC and new
router have anything to do with the problem (whether or not it has
negotiated 10baseT or 100baseT). The uplink connection to your ISP is the
most likely source of the problem. One thing you should check though is the
stats on the interface. Do an ifconfig and check for errors. If your
interface stats are showing a lot of errors then that could cause a
throughput issue as you will get timeouts & retransmissions occuring.
However as I said it is far more likely to be a problem with the upstream
link to your ISP. If you have the manual for the Verizon FiOS 5/2 device
you might be able to figure out how to get link statistics out of it.

Klazmon.
