Domains not resolving

[Chris F.A. Johnson]

    My landlord has just switched form Teksavvy on DSL to Teksavvy on cable.

    The DSL modem, 2wire with built-in wireless, worked with no problems.

    He now has a cable modem plus a DLink DIR-815 wireless router.

    My laptop, running Mandriva 2010.1, connects with no problems.

    My desktop, running Mandriva 2010.2, connects but does not resolve URLs
    (Firefox works fine; lynx does not). I can connect (ssh, smtp, POP3, etc.) if
    I give a dotted quad IP address, but not with a URL.

    This is info from both machines:

$ iwconfig wlan0  ## laptop
wlan0     IEEE 802.11bg  ESSID:"MY HOME 1"
           Mode:Managed  Frequency:2.462 GHz  Access Point: BC:F6:85:C0:A4:E1
           Bit Rate=36 Mb/s   Tx-Power=27 dBm

$ iwconfig wlan0 ## desktop

           Mode:Managed  Frequency:2.462 GHz  Access Point: BC:F6:85:C0:A4:E1
           Bit Rate=48 Mb/s   Tx-Power:20 dBm   Sensitivity=-121 dBm

           Power Management:off

           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:0  Invalid misc:0   Missed beacon:0


    Does anyone have any idea how to fix it?
