I've got Alcatel Home upgraded to PRO version. I've got a 10/100 Switch. I connected the modem to switch using Straight cable through Uplink thing, also tried Twisted-Pair cable from modem to normal port. my problem is that I don't get ping from the modem on the PC that is connected to the Switch also. 1. All the cables work 100% i know. 2. tried assigning the NIC settings manualy : IP: 10.0.0.1 subnetmask : 255.255.255.0 also tried 255.0.0.0 gateway : 10.0.0.138 DNS : Tried my ISP's and also tried putting 10.0.0.138 3. after #2 didn't work [no ping from 10.0.0.138], I tried using DHCP Server through modem. didn't work either. thouh the modem works well when connected to the PC directly. the Switch ought to be working fine, because the Network works [file sharing and all]. Also try limiting the network to Half-Duplex. didn't work. Please advise me.
