WET54G Close Up

WET54G Close Up

Recently after setting up a Linksys Wireless-G Ethernet Bridge WET54G to bridge an Xbox 360 to a wireless network rather than using a Xbox 360 Wireless Card, it randomly lost its configuration. Reconfiguring this device should of been easy , but not when Linksys try and make it hard as possible to get the information out!
  1. Right , so first port of call , hold down the reset button for 30 Seconds to reset to factory configurations
  2. Linksys’ “quick guide” states that you need the CD to start the Configuration Launcher .. Who Keeps CD’s Nowadays?
  3. Try and find the Software on the WET54G Page with My Version 2 Product
  4. Nothing! , Contact Linksys 24/7 Chat Support , After 10 Mins , shows me back to the download Page
  5. After more investigation this is only available on the Version 3 Product Page ??? Here’s the link you need!
  6. Installed the Configuration Software however if you are doing this remotely for a friend via his Wireless Internet and the Bridge is connected to the Ethernet Port , the software can’t check both ports even if if windows can ping it!
  7. Right , Go to it Manually , its standard IP address is
IP Address : Username : *Don’t Enter one!* Password : admin From here you can fully configure the product and rejoin it to the wireless network!

  • ATM Quality
  • On the Fly Trade Up Between Raw Capcity of Line and Quality
  • Backhaul is how one Wimax tower would speak to the other ( 5Ghz Range )
  • Needs to be Lower the 10 Ghz Due to the Technogy for Long Distance
Non Line Of Site ( Convient forMobile Users )
  • Lower Frequency ( Under 10 Ghz )
Line Of Site ( Higher Bandwidth Lower Error Rates )
  • Higher Frequency (10 – 66Ghz )
Inverse Fast Fourier Transform is used in a WiMAX transmitter Fast Fourier Transform) is used in a WiMAX receiver How It Works?
  1. Base Stations want to communicate with WiMax Access Point By Random Interupt
  2. MAC uses scheduling Algorithm
  3. Once Completed they are given a Slot at the access point which can be adjusted and will remain the base stations untill not needed
  4. QoS Is Balanced By the access point depending on the users QoS Settings
