    Hello all...

    This was my original question>>>>
    just updated my WRT54G router with the latest Satori Firmware.
    Love the increase range/power output afforded by this update... fixed a bunch of deadspot problem in my home.... wonderful!

    Here's my problem... I have four computers hardwired to the router.. all continue to work just fine. They still "see" each other across the network and all have perfect access to the printer.

    My wireless laptop, however, is experiencing some trouble. It has full access to the web.. no problem. However, It cannot see, or be seen, by any other computer on the network.... it also cannot access/see the printer.....
    hmmm.. any suggestions??

    thanks to all

    I attempted to fix the problem as suggested by turning off loopback.
    doing so stopped internet access from not only the wireless computer but all four of my hardwired systems.....
    any ideas what might be going on??

    thanks to all...

    or ICS of other WinXX variants?

    I have very similar problem.

    Ip connectivity (ping) from wired LAN pc to wireless laptop. OK
    Ip connectivity (ping) from wireless laptop to wired LAN pc. FAILS
    Ip connectivity from wireless laptop to internet. OK

    I also disabled loopback but have noticed no difference.

    laptop running windows 2000, on wireless DHCP
    pc running windows 2000, on wired LAN DHCP

    Route Table (from web admin)
    Destination LAN IP Subnet Mask Gateway Interface
    XXX.XXX.94.0 WAN (Internet) LAN & Wireless XXX.XXX.94.1 WAN (Internet)

    Firmware Version: Satori-4.0 v2.07.1.7sv
    WRT54G V2.0

    (none):[~]# route
    Kernel IP routing table
    Destination Gateway Genmask Flags Metric Ref Use Iface
    XXX.XXX.94.0 * U 0 0 0 vlan1 * U 0 0 0 br0 * U 0 0 0 lo
    default XXX.XXX.94.1.opt UG 0 0 0 vlan1

    Anyone have an idea what might be wrong?

    zonealarm still can block traffic even when it is disabled.

    I fixed my problem - it was due to a combination of firewall blocking ping replies and bad windows networking setup.. not acutally a problem with the router at all. dohh.

    Thanks for the firewall, etc suggestion Toxic - it got me looking in the right direction.

    Restart router

    I had the same problem when I disable loopback, couldn't connect to internet from any computers. Just turn the router off and back on, it should start working.
