Unable to change Power State of 802.11 wireless radio

The Fn+F5 key combination of my thinkpad X31 suddenly stopped working and kept giving an error dialog saying that: Unable to change Power State of 802.11 wireless radio.

I recalled I did change the configuration of my intel wireless 2100 3B adaptor recently and disabled a couple of protocols from its driver listing. After I enabled the "WLAN Transport" protocol as shown in the screenshot below, the Fn+F5 key worked again! It seems the hardware driver relys on WNMP to switch the power of the wireless radio.

Make ATS 6011S work with Stanaphone-IN

After my old PAP2 ATA died, I tried to make my ATS 6011s work with Stanaphone since I can use Voipbuster from my cell phone with its local access number. The WAN port of 6011s is connected to one of the LAN ports of my router as is PAP2.

The HTTP server listening port of the built-in router is 8080 instead of the standard port 80.

The following was obtained from Ref 1 after a search in the internet:
Login: user/welcome - Regular user login that changes router settings
Login: tech/kaboom - Administrative that also adds voice changes

I set the NAT WAN Address to the WAN IP address of my router and NAT WAN Port to 5060 in the voice setup as shown below (click to enlarge):

I also forwarded the SIP and RTP ports to the ATA and set an IP filter to block its provisioning on my D-link router as shown below:

Then I did a reset of the unit from the handset "VOIP Settings->Reset" menu and waited for a few minutes. After it restarted with the above setting, the SIP status became "Needs Restart" as shown below, but I can receive incoming calls on my Stanaphone-IN number and call out too.

My PAP2 stopped working

The VOIP ATA LinkSYS PAP2 at my home stopped working today. It has been working without any problems for more than 2 years since Oct. 2005. Now neither FXS port has dial tone any more although both lines appear online on its web interface. The two LEDS for the line status are both solid blue on the unit. I think the analog telephony chip which connects to the two FXS ports must be dead.

I ordered a PAP2T-NA as a replacement for ~$50 (including shipping) from Telephony depot. The model number on the box says PAP2T-NA but the sticker on the back of the unit says PAP2T. Anyway, after plugging into my home network, I can access its web server immediately:
  • DHCP is enabled
  • Blank passwords for user and admin
  • Provision is enabled with blank GPP-K value
  • On the info page under Product Information:
    • Product Name: PAP2T
    • Software Version: 3.1.15(LS)
    • Hardware Version: 0.3.5
The web interface is essentially identical to that of PAP2. So I changed the passwords and upgraded its firmware to the latest official version 5.1.6(LS) obtained from Linksys website after selecting "Version 1.0".
