Well, I recently found my 3c5x9cfg.exe/FreeDOS bootfloppy and popped it into a PC with a couple of the cards from my old 486 LEAF box. First of all, it appears that I was mistaken about the cards that I had. There were three 3C509's and only one 3C509B. This made no difference before, so I hadn't paid any attention. I ran one of the 3C509's and the 3C509B card through the config utility. The 3C509 had no option for full duplex or Plug and Play whereas the 3C509B had an option for both, as expected. Plug and Play was disabled and Full Duplex was enabled. Probably putting the modem on the 3C509B card would have made a difference. I'll probably mess around with this a bit more over this weekend but just end up keeping the 486 as a backup. I'll write again when I find out whether or not using the B card makes any difference so that people in my situation will have some other options besides replacing their othewise-working box.

Re: [leaf-user] Cable Modem speeds with Bering-uClibc
Exactly Bob, and this was why Andrew, I suggested using the DOS utility to force half-duplex, full duplex with testing performed each time. And as far as the networking terms go, errors = bad. Pretty simple. As you can see with your test, every one of those errors are overruns. 3: eth0: BROADCAST,MULTICAST,NOTRAILERS,UP mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:20:af:17:57:b2 brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 741077003 1773743 18161 0 18161 0 TX: bytes packets errors dropped carrier collsns 438580149 852431 0 0 219 2150 4: eth1: BROADCAST,MULTICAST,UP mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:20:af:3f:53:d4 brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 440479032 855735 42710 42710 TX: bytes packets errors dropped carrier collsns 680103683 783492 0 0 0 4193 Andrew, you've spent this much time with this, what's another 20 minutes with the DOS utility (which was designed for that card) to change the settings?

Re: [leaf-user] Cable Modem speeds with Bering-uClibc
I half understand duplex (don't bother explaining it - I'll look it up for myself) but I don't understand how duplex could be negotiated improperly? I speak from experience! I had EXACTLY the same problem, Internet was slow through the Leaf box, directly connected PC bypassing the router, it was fast. But in testing (ie Leaf not connected to cable modem) it was fast. It was an older box, like yours, with older cards, like yours, and it turned out that duplex was negotiated incorrectly. Once I solved that, it was fine. - Bob - Take Surveys. Earn Cash.

Any number of things could cause that. My concern is, sometimes Motorolas don't handle forced duplex settings well, and sometimes half-duplex will make things problematic to begin with. Example: I have an SB5120. I was testing my father's rather old Wireless B Linksys router because he was getting constant network drops on his DSL. I hooked it up, and it ran okay, but I saw some of the same drops. Upgraded the firmware to the latest and greatest, and suddenly there's a dropdown to configure it for 10 or 100, full or half, but no autodetect. So, since my downstream is 30Mbit/sec, I set it to 100 Full... and it started running like a slug. 100 Half didn't help any either. So I hooked up my PC to the modem direct, and discovered that the SB5120 doesn't like forced duplex modes. 100 Full and Half ran like a slug, but autodetect would configure for 100 full and it ran like a champ. So, it's possible that you've got a similar problem. The difficulty in determining that is that it could just be the firmware on my modem that caused that, and every cable provider does their own firmware releases. You can always try connecting the laptop and forcing 10 full and 10 half to see if the performance is similar to what you're getting out of the LEAF box. If you are, then the problem is that the modem doesn't like the forced settings. If not, then it's probably something on either the cards or the motherboard. Out of curiosity, have you tried switching which card is connected where? In other words, Eth0 internal and Eth1 external? For what it's worth, I've acquired a replacement box that has PCI slots in it and I'll set up my LEAF box with 3c905's (10/100) which should (hopefully) solve the problem. Probably will. I myself had switched over to 3c905Cs when I finally got rid of the 486 system. George - Take Surveys. Earn Cash.

Thanks. Andy What are you using to download? Do you maybe have ports that need to be forwarded to your laptop when it's behind the router? If this isn't a simple port issue, then perhaps there is an issue with one of your NICs on the router. It's possible this old box is starting to ware out - it's got to be over 10 years old after all. It's about the only thing I can think of if you were getting better performance from this same router before. Unless something else has changed (different software or hardware?). Changing it's position in a network shouldn't make a difference to the speed traffic passing through it. ...Izzy - Take Surveys. Earn Cash.
