Thibor 15c : Anyone tried same static IP to 2 adapters on same computer?

    Finally took the plunge and upgraded to Thibor 15c on my office WRT54G v2.0 (the v3.1 at home will be next) and was trying out various features.

    I want to assign same IP address to one ethernet and one wireless adapter on the same notebook - not connected to the network at the same time of course. I tried this and was locked out of the router - no IP assigned whatsoever to either type of connections.

    Has anyone tried this and was successful with it?

    Here's why. With the new office we are setting up (opening is in 2 weeks!), some folks including myself will use notebooks as their main PC and with notebooks they tend to move around; nothing unusual here. I plan to connect our notebooks to the network at the ethernet adapter when we are working at our desks, and only connect to wireless when, say, in the conference rooms or discussing issues with a colleague at their desk on our notebooks. Naturally I want the same IP assigned to the same computer regardless of whether an ethernet or wireless adapter is used.

    Any suggestion or pointer? :biggrin:

    Have you thought of using a VLan...

    wired... 192.168.1.130
    wireless ... 192.168.5.130?

    Thanks but VLAN is not an option. Need to keep things simple for the folks in the office to troubleshoot when I travel.

    Have you tried spoofing the MACs so they are both the same and use static dhcp?

    i think having the same IP with a couple adapters will cause confusion, the first time someone "forgets" to disable their wireless adapter when they plug in its going to scare them when it says a duplicate address was found. whatever NIC gets the address first should remain in working condition tho until its disabled and then connection renewed on the desired adapter

    HA! Thanks! I haven't thought of that (!)

    However, this may not be available to everyone. For instance, my notebook doesn't support this on either adapter, whether in the driver advanced settings or the configuration software. Newer generic version drivers do support MAC Address Cloning but they cause problems such as waking up from standby or non-working wireless connection :mad:

    Disabling the network adapter was one of the first things I tried, but the thing was after using Static IP section to set the same IP address to both ethernet and wireless adapter MAC addresses, I rebooted router and computer to reconnect from scratch, and I couldn't get IP address assigned either by ethernet or wireless.

    what are you needing to have the same IP for 2 adapters in the first place tho? are you setting up file sharing via the IP's and dont want to deal with multiple IPs?

    I guess i've never tried what your wanting to do, i use a windows server for my DHCP at home.

    File sharing is not the issue here - can always map a network drive to a computer. Nor is network printing but we do use networked printers with their own IP addresses.

    I simply want to restrict each computer to a single IP address, but it looks like adapter MAC Address Cloning may be a way forward.
