I've been trying to solve my Dell desktop's new wireless network problem by using Browser Linux and a Linksys wireless-g adapter. Both the computer and adapter worked well in the past. Last night I attempted to follow 'How to configure wifi from the command line' posted on www.murga-linux.com/puppy as follows.

#lsmod
returns the adapter's driver rt73usb.

#ifconfig -a
returns the adpter's hardware address 00:18:F8:A4:9B9.
--------------------------------------------------------
#iwconfig
returns

lo no wireless extensions
eth0 no wireless extensions
wlan0 IEEE 802.11bg ESSID: off/any

#modprobe rt73usb
returns

#ifconfig wlan0 up
#iwconfig wlan0 essid 8zti3

#rm -f /var/lib/dhcpcd/*.info

#dhcpcd -t 30 -h puppypc -d wlan0
returns

dhcpcd:wlan0: waiting for carrier
dhcpcd:timed out

dhcpcd:timed out
------------------------------------------------------------------------
I want to point out that I use WEP security mode and that the Network Setup screen shows
"Name: 8ZTI3 Encryption on strength 26/70".

Any help will be much appreciated.

My guess is that you do not have the proper drivers for your wireless card.

Could you provide more information about the make/model of your computer and of the wireless adapter. If the wireless adapter is a USB device, as you seem to imply, this link should help you identify it. If it's a PCI device, the lspci command will reveal it.

Does the access point have broadcast essid enabled?

I have a Linksys USB adapter that will not connect to an access point with broadcast essid disabled (i.e., hidden access point). Works fine otherwise,

astrogeek,

My router has essid broacast enabled. Thanks.

this info would be useful to help diagnose:

Frank,

Thanks very much for your input. Rt75usb is the proper driver for my Linksys WUSb54GC wireless-g adapter, which has worked on all my HP and Dell desktops in Windows X and Unbuntu for the past several years in all locations, near or remote.

Something physical must have happened to this Dell Dimension 2400 desktop recently since the adapter cannot communicate with the router in either Windows XP or Linux Mint 17.1 Mate. Everything except wifi seems to be working. The Dell computer is still in its same remote location. I happen to be using Browser Linux to debug my wifi problem mainly because it seems an ideal wifi debugging tool. I may switch back to Ubuntu and will report back to this site.

Many thanks again.
