Speedstream 4100 + Trendnet 4-Port broadband router TW100-S4W1CA

[kno]

Hi

I am using Speedstream 4100 + Trendnet router TW100-S4W1CA at home. The internet will work if router is removed. The internet will not work with router connected. I hv verified the router is functionng in my office network. The router worked with Motorola 2210 modem before too.

Is there any known compatibility problem between Speedstream 4100 + Trendnet router TW100-S4W1CA ?

Or is there any particular setting in Speedstream 4100 or Trendnet router TW100-S4W1CA that may cause the problem mentioned ?

thks & rgds
