WBP54G

Created by: jht2,Last modification on Fri 14 of Dec, 2007 [12:33 UTC] by VoilensP

Linksys WBP54G


The WBP54G is a very small Wi-Fi 802.11g-to-Ethernet adaptor.
It can be used with to turn the SPA-941 Phone into a wireless desk phone.

It was on display at the Boston October 2005 VON show.
There is a picture here:

Also may be used a simple transparent wireless bridge between non VOIP devices

Requires a 5 V adapter
Cheaper than other stand alone wireless G bridges available
There is a warning on the product packaging that states the device is only to be used on Linksys VOIP devices (but it works with other devices)

Internals

The unit is easily opened by prising apart at the DC power connector.

Opening this up shows chips with the following legends
  • MX T053319 29LV800CTTC-70G 2M355100A1
  • EtronTech EM638325TS-6G J423703ABF856.11M
  • Something under a heatsink which is HOT to the touch
  • An unmarked RF-screened flat can, about 23x23mm
  • A small corkscrew piece of wire at right angles to the PCB, presumably the antenna

Caveats

Some people have been unable to get this device to work.

In my tests with WPA-PSK, it did not work first time. However, after changing the SSID of the AP it worked, but then it also worked when I changed the SSID back again :-( After more changes it failed again. It seems to be happier if the SSID has no capitals or spaces in it, but I can't be sure.

This device is not IP manageable. The Windows setup software works by sending layer 2 frames with ethertype 0x8888.

There is no external antenna, so the sensitivity may be low.

If you wanted to use this for wireless access in a hotel, you'd still need a laptop to configure it, in which case you might as well just use a soft phone. Or consider a wireless AP which runs OpenWrt instead.

However, it is very cheap and small, and doesn't require a separate PSU if your phone takes 5V DC.

333Works perfectly fine with computers

by prestonlewis, Tuesday 13 of May, 2008 [01:47:51 UTC]
I currently use my WBP54G bridge to connect a DSL router with a cable network. Works perfectly fine: reliable, never fails, etc. Yes, it did take me twice to set the thing up. You have to use the Linksys CD which comes with it and the first time everything looked like it worked fine but no connection. Ran the setup a 2nd time and after the setup was complete, the bridge worked as expected. The Linksys CD goes though a lot of stuff you don't need to worry about like how to hook it up with a Linksys VOIP product, you just "next" your way through those pages. Finally it searches and finds the WBP54G and then searches for available networks. You click the network you want to bridge with, enter the encryption method, it run checks it's connection to the AP/wireless router then checks it's connection to the network and reports OK. Then it goes into more useless pages about setting up the Linksys VOIP device. You can just exit at this point.

Yes, you may have to run the setup twice (I had to) even if it reports success it may not work. However, twice was the charm for me. It puts out a respectable 13dbi in wireless G mode. The internal 1dbi antenna leaves a bit to be desired, I've considered opening it up and putting in a more robust antenna connection for an external antenna but haven't yet. I use it to bridge my DSL network with my cable network and it works wonderfully. However, you can use it as any bridge with just a computer (or any computing device) or connect it to a switch/hub to service multiple computing devices. It has no IP address so it's pretty transparent. You do have to use the Linksys CD to make any changes. All you need is a 5v 2a adapter or if you have a Linksys/Sipura VOIP device, you can plug the Sipura's 5v adapter into the bridge and then the bridge's output 5v adapter into the Sipura/Linksys without having to connect any network connections. Both My Sipura and the bridge both plug their RJ45jacks into a switch and have no network relationship they just share a single 5v power supply.

$35 at amazon.com including shipping. Can't beat it. It'll do anything any bridge will do, as I said you can plug it into a switch or hub and service multiple devices using the bridge. It's only drawback is having an internal helix omnidirectional 1dbi antenna. If you are a soldering kind of person, just open up the device and install a jack on it's side so an external antenna can screw into it.

333So it DOES work on the computer?

by jongscx, Thursday 13 of March, 2008 [14:02:23 UTC]
@RAJU M.
1) Is the device indeed functional as a 802.11 G wifi bridge for a personal computer as well? I have yet to find a definitive answer on this.
2) If so, is it set-up via a web/browser-interface or a config program.

I am asking because I am looking for an inexpensive way of connecting my older computing device (an NEC Mobilepro 790) to current wifi networks. It has a 16-bit PCMCIA card slot and no usb, as well as running Windows CE 2.0 ( yeah, it's old). I have a wired ethernet card for it, and have thus been able to get websites this way. However, the only wireless options stop at 802.11B with WEP... unacceptable.

333WBP54G & GXP-2000 Why Won't It Work???

by pauloshea42, Saturday 06 of January, 2007 [08:31:32 UTC]

First WBP54G I got turned out to be dead on arrival - next one I ordered configured up perfectly. When connected to the ethernet port of my laptop it connected me to my wireless network and assigned me an IP. However as soon as I connected it to my GXP-2000 both devices indicated they had an ethernet conn. (green eth indicator on WBP54G and icon on GXP lcd) but the dongle wireless indicator never lit up (as it had done with laptop) so obviously the GXP continued saying "no ip".

Please has anyone got any ideas? On the verge of ordering a belkin wireless bridge but would really like to avoid spending more $$.

I have eliminated power supply. Whilst both are 5V (well one 1.2A and the other 1A) I have powered them both independently (54G with psu from my sipura 2002).

Anyway has anyone made this work? (and how..?)

333Works great with Snom, setup requires Windows

by ptpittman, Friday 05 of January, 2007 [06:29:48 UTC]
I bought two of these for use with a Snom 300 and 360 - they work perfectly well on my WEP network with the Snom power adaptors as these phones also take 5v with the same connector and polarity.

The only prob is you cannot configure via IP - you must use the windows based software. Required use of boot camp on my mac, though some have reported success running the software through Wine. Once the devices are configured, though, they're completely transparent to use.

333How well does it fit in?

by mbsat, Saturday 29 of July, 2006 [18:55:12 UTC]
Hello,

Does anyone have any pictures of how this device fits into/behind the phone? Or does it just dangle off the back?

Thanks :)

The way this is designed it works has a small power inlet and and a power outlet. For use with other linksys devices It only requires one power adapter. If your grandsteam device plug is different, it would not be too difficult to mod a wall adapter to supply both the grandstream phone and the WBP54G at the same time.

Chip
The stated voltage is 5V on the specifications. In my case I am using the WPB54G as a wireless bridge to a stand alone computer. I imagine I can create a USB to 5V connector to steal 5V off the USB. I am currently using an old 5V adapter from a D-Link USB hub that was not being used. Not sure if you can use it with higher voltages but it is simple to setup and just works.

333combination poe injector/wi-fi bridge

by dao777, Monday 01 of May, 2006 [02:56:38 UTC]
This is close to the dongle of my dreams but misses. I have a gxp-2000 (5v), a power outlet, and an 802.11b/g wireless network. I want a device I can plug into the power outlet which bridges my wireless connection and delivers PoE to my gxp-2000. Is there such a thing? If not, wtf? This seems obvious, and of broad utility.

333Voltage range?

by lschweiss, Sunday 30 of April, 2006 [22:43:37 UTC]
Anyone know what the actual range of voltages this will work on?

If it's anything like the Linksys routers they will work from 5 to 25 volts. But I don't know what kind of voltage regulator they put in these.
