Problem with SBC Yahoo DSL and Linksys Router
First post...I'm completely new to linux and purchased a new whitebox job from Monarch Computers about a month ago with the intention of replacing my old Windows computer. I was very excited about getting this new computer with a AMD Athlon 64 3500+ and SuSE 9.2 Pro 64-bit because it sounded like it'd be a nice smooth ride compared to my old computer that would lock up every time I used it. But, so far it's been a tug-of-war with this thing - if it's not one problem it's another. The big issues right off the bat were getting the awesome nVidia card to work with Twinview, getting an i-Pod to show up, and getting the SBC Yahoo DSL connection that I've had for about a year to work. So far I've resolved the former two for the most part, but the DSL has been a big problem on and off - not to mention the biggest problem, since as long as I'm online I'll be able to find solutions for my other problems.
Initially I simply moved my Windows box, which worked fairly well with the DSL - a few dropped connections, but nothing reconnecting didn't solve - and put my new linux box in it's place. Plugged the stock SBC DSL modem, Speedstream 5100 (four lights), into the onboard ethernet, installed roaring penguin and I was off. It seemed to work great. It took all weekend, but eventually I got two NEC FE950's running side by side on the GeForce 5700 FX at 1600x1200 each, but through all the research it took to get that working the DSL connection kept dropping. I'd try to reconnect with adsl-connect but to no avail. Only would restarting the computer and running adsl-start fix the connection until the next time it dropped, perhaps after an hour or so of continually hitting web pages.
Well, after a disaster with trying to re-compile the kernel for the first time to get the i-Pod to work, I simply popped the SuSE 9.2 DVD back into the drive and reinstalled the whole thing - I didn't have anything to lose but time since I haven't transfered anything from my old computer to the new yet. After getting the fresh system back up I tried to connect with adsl-start after setting up again with the same settings and it wouldn't connect.
I came home from CompUSA a few days ago with a new Linksys router after reading of being able to magically get DSL connections through a router and we come to my current predicament:
I've got the old windows machine up and running next to the new linux machine.
Both are connected to a four wire Linksys EtherFast Cable/DSL Router (BEFSR41).
The router is connected to the Speedstream 5100 modem.
The router is configured via the web interface to have a PPPoE connection with my various ISP settings including username, password, MTU=1492, and the correct DNS's for my area.
Turn the windows machine on and I'm online. I think I'm actually surfing faster than I have before with the silly SBC connection manager.
Turn the linux machine on and I'm online too. It's noticably slower than the windows machine and after hitting a couple of websites I'm dead in the water. Any web browser I try in the linux box timeouts on any website I hit. If I'm lucky I can still browse in Firefox on the windows machine. But usually it's no internet for either machine while both are on. I'm trying this experiment now it seems like the windows machine still has a connection but the linux machine got through a few sites before stopping.
Turn off the linux box and after a few seconds the windows machine definitely gets its connection back if it didn't maintain it for the whole time anyway.
If I try it with just the linux box on I'm lucky if I get a connection at all and if then it's only for a minute.
this is what ifconfig eth0 gets if it at least got a connection at one point:
Link encap:Ethernet HWaddr 00:50:8D:EB:B7:07
inet addr:192.168.1.101 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::250:8dff:feed:b707/64 Scope:Link
UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1
RX packets:257 errors:0 dropped:0 overruns:0 frame:0
TX packets:249 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:27870 (27.2Kb) TX bytes:17616 (17.2Kb)
Interrupt:201 Base address:0xb400
If it never gets a connection upon boot then it's the same without the IP. The ethernet is configured with DHCP, Default Gateway left blank, and in YaST the MTU=1492, but as the ifconfig eth0 shows above it is still 1500. I've tried:
ifconfig eth0 mtu=1492
...but it doesn't change it or I get an error after waiting a 30 seconds (inconsistent):
mtu=1492: Host name lookup failure
If I go into YaST and change some detail such as MTU=1400 and then change it back to 1492 I'll get the internet connection back but only for a second.
An interesting thing shows up in the tail of dmesg:
eth0: Invalid MTU
Here's some details for my system:
OS: SuSE 9.2 Pro 64-bit
I've got the SBC Yahoo DSL Basic package with dynamic IP's.
I've tried switching cables around, reseating the CAT5 jacks, power-cycling the modem. Doesn't change anything.
I've run out of ideas. Thanks in advance for any help.
SBC Yahoo and Linksys Router
I had the same problem and tried calling SBC and Linksys tech support several times.
After searching the net, I found this solution which worked!
