    Motorola SB5101 not renewing ip leases

    Hello All,

    Have a motorola sb5101 cable modem which was working fine for about 3 months but has now developed a possible fault.

    It seems to drop off every few hours, but then reconnects within about a minute, but thats enough to disconnect my internet apps.

    Disconnected my linksys wrt54g and plugged one of my computers directly into the motorola. Found event viewer showed problems of ip lease renewal every 5 hours or so. Lots of logs along the lines of "Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address ", then eventually it drops off. When the lease does expire, the motorola re-issues the computer with the ip and its fine, altough sometimes a restart of the motorola is required.

    All computers and linksys router behave in the same way of not being able to renew ip lease.

    If it helps, my setup is as follows, rogers cable comes in from wall, into 3-way splitter, one goes off the the tv box, 1 to the phone and one into the motorola. My computer into the motorola using rj45.

    Have done the change cables, restarting in order, etc, no fix. Also, it happens on anything plugged into the motorola so i know its not the linksys, other computers, etc. laptops work fine at friends houses, so must be soemthing on my install.

    Below is an example log from the motorola.

    Would appriciate any advice. All rogers can offer is for someone to come round, but that won't be for a while and i really need to get it running.

    Please reply to this group or email me at: mikesmith20001@hotmail.com

    everything looks a little jacked, s2n is high signal is low kinda and upstream is kinda low, your connection needs some fine tuning.

    i would let them handle that...hopefully they can. the fact that it isn't like just low signal or high upstream makes this a bit of a tricky one...you follow?
