84 C HAPTER 6: T ROUBLESHOOTING ■ If you cannot b rowse to the Router , use the winipcfg utility in Wi ndows 95/98/ME to verify that your computer has received the correct addr ess information fr om the Router . From the Start menu, choose Run and then enter winipcfg .
Wireless Networking 85 4 Press and hold the Reset button on the r ear panel (see “Rear Panel” on page 13 ) for 5 seconds. 5 The Router will r estart, and when th e start-up sequence has completed, browse to: http://192.168.1.1 and run the co nfiguration wizard.
86 C HAPTER 6: T ROUBLESHOOTING Additionally consider moving the wireless computer closer to the Router to co nfirm that the building stru cture or fittings are not adversely affecting the connectivity . If this r esolves the problem consider relocating the Wireless computer or the Router , or trying a differ ent channel on the Router .
Recovering from Corrupted Software 87 Recovering from Corrupted Software If the system softwar e has become corrupted, the Router will enter a “rec overy” state; DHCP is enable d, and the LAN IP addr ess is set to 192.168.1.1. Follow the instructions below to upload a new copy of the system software to a Router unit in this state.
88 C HAPTER 6: T ROUBLESHOOTING Frequently Asked Questions How do I re set the Router to Factory Defaults? See “Forgotten Password and Reset to Factory Defaults” on page 84 . How many computers on the LAN does the Router sup port? A maximum of 253 computers on the LAN are supported.
