If connected directly, router can't talk to DSL modem |
|
|
Hello all,
I had a working setup where my wireless router+firewall (SMC Barricade)
connected directly to my SBC Yahoo DSL modem. The router was setup to
obtain a DHCP address from the DSL modem.
In the last few days, the router fails to obtain a DHCP address from
the modem. The green light next to the ethernet port on the router and
the DSL modem doesn't light up which indicates that the ethernet ports
are not connected.
The router can obtain a DHCP address from the modem if connected thru
an ethernet hub. Can someone explain why they can't talk to each other
if connected directly but can if connected thru' a hub?
thanks for your time.
Raj. |

Are you using a normal patch cable (or crossover cable, which would be the
wrong type for that). Have you tried a different cable? Once when I
thought my modem was acting up, one of the cable plugs was not quite
seated in the jack.
You may be able to get more help from SMC forum on
http://www.broadbandreports.com/ alias http://www.dslreports.com/ (include
SMC model and firmware version).
My primary experience with SMC was a flaky wireless router (7004AWBR).
One of its numerous problems was that it refused to autonegotiate speed
with any laptop PC card nic, 16-bit or cardbus, unless I forced the nic
down to 10baseT speeds (full-duplex worked). SMC never could fix its
faults with firmware upgrades. Its only usefulness was its power brick
when the one on our SonicWall at work failed. |

Raj,
even though you dont list your dsl modem brand, your dsl modem appear
to have routing functionality & running 2router back-to-back can b
grounds for a lobotomy... if applicable, set the dsl modem in
"bridged" mode, set the smc to run pppoe and let the smc router do th
routing.
P2E.
