Hi,

I have a Cisco 1605R. When I download through the router it download only at 50 Kbit. When I download directly, without go through the router, my speed is at 500 Kbit ! If someone have an Idea ?

This is my Running-Config :

Try this

router>en
router#conf t
router(config)#go faster

lol..j/k. Seriously, try

router(config)#ip cef
router(config)#end
router#wr

damn it burt...you're the second one today that stole my thunder...s'ok, s'alight, we all have a common goal here...now where'd my dog go, i've got to go kick him

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

What, the "go faster" config?lol

Here---you can have some of my thunder...pull my finger...

That's just...wrong...so so wrong on so many levels lol...

It seems to be a deplex issue. IP CEF change nothing. I put default duplex on each interface. Better now, over 300, but the COL ligth flash like ACT ! I don't know why. Maybe me cable are bad. The thing that I don't understant, why is on the both interface ?

Is it possible if I have a problem on one interface that the both are affect for COL ligth ?

Thanks
 
What do you mean you put the interface on default duplex? Did you set them to auto? Can you verify that both interfaces have either been set, or auto negotiated to full duplex? The collisions on the interface still make me think of a duplex mismatch. But I'm just a nooblet.
 
thanks burt!

router>en
router#conf t
router(config)#go faster

i spit my coke all over the screen
 
I just have control on my PC, when I put Full Duplex on both side, PC and Router. Still have ligth COL flashing.

For auto negociate. I can't find the command. Don't forget that it's on a 10 Mb LAN on this router. I'm sure I have control only on the duplex.
 
Well for auto negotiate you would just do a no duplex full, but if your set the duplex manual then no need. Have you cleared the counters? Do that for the interface and then see which counters are actually going nuts. Should tell you a bit more about whats wrong. Have you tried setting putting a little switch between them just to see if it helped?
 
router(config)#light col
router(config-light)#stop flashing so fast

Okay...DON't try that...

Please name all the devices on this network, accessed by this router. Someone may be attacking you...do you have FTP service on your computer?
And do what niblet says, but FIRST post sh int (all of them), clear the counters

router#clear counters

That is actually the command...lol

Download something to generate a lot of traffic in and out of the router, then after like 10 minutes, do a sh int

router#sh int

again, and post it.

Niblet---for auto, it is

router>en
router#conf t
router(config)#int e0
router(config-if)#dupl auto
router(config-if)#end

OK, this is my setup now :

Router 1605R
Switch 2924XL-EN

1605R Ethernet 0 ------> 2924XL FastEthernet 0/5
1605R Ethernet 1 ------> ADSL modem
PC Ethernet ------> 2924XL FastEthernet 0/4

Nothing else on that network. Still have a lot of colision. I don't have any control on the ADSL modem. My two Ethernet on the 1605R are in duplex auto.

I did exactly what you ask Burt, and I post my result of the show interface.

I suspect that you aren't really having collisions.


The line "Unknown duplex, Unknown Speed" on both interfaces puzzles me. Seems it doesn't know what settings its using. Which the collision counters would make sense to me if the switch is set/negotiated to full duplex and the router is stuck at half. I hope burt can shed a little light.


Can you log into the cisco switch and do a

show interfaces status

to see what the interfaces are auto negotiating to?

Tell us what the results under Duplex/Speed for 2 used interfaces are. Is it a-full a-10 or just full 10 ??
 
I could be wrong, but I think that router only supports 10/Half on it's ethernet interfaces.
 
Throw out the 1605 and go get a soho broadband router. Sounds like its on its way out.
 
quote:I could be wrong, but I think that router only supports 10/Half on it's ethernet interfaces.


Could be. If it is you can run both switch and router at half and get away with it. Why do you want to run that router btw? Just learning? If so try half duplex. If not get a new router.
 
Wrong---the router supports full. In fact, you could do router on a stick with the right image.

The modem is likely set at 10/half. The collisions and deferred packets are from CSMA/CD. Set the interface to half duplex (just e0), then clear the counters and post sh int again...

Burt
 
I found my problem. The cable on the interface Ethernet 0 was bad. I put a new one and set the interface Ethernet 0 in duplex full. No collision at all. Thanks for everyone for your help on that issue.
