***********************************************************************************


  The 'UK2' firmware is intended for use only when the regular UK firmware
  is unable to reliably sync. with your line in situations of poor
  quality ADSL signal/lines. Use regular firmware otherwise. To obtain
  the UK2 firmware, download from the same URL, using 'uk2' instead of 'uk'
  to the end of the filename


Changes/Fixes Since Firmware 2.5.8UK (Beta)
-------------------------------------------

1. Corrected an issue with IP filters in VPN tunnels


Changes/Fixes Since Firmware 2.5.7UK (Release)
----------------------------------------------

1. Improved WDS Stability


Changes/Fixes Since Firmware 2.5.6UK (Release)
----------------------------------------------

NOTE : To check your WLAN hardware version see "Wireless LAN Setup" > 
"Wireless Information" > "Firmware Version" in the web interface. 
The last digit is the hardware version, e.g.  v1.2.8.16.04.2 means 
the wireless hardware version is 2.  If you have
version 2 hardware, you can use the WPA facility.


[ Wireless LAN (Vigor2600G) ]

This firmware includes various improvements to Wireless LAN stability
and integrates the various changes which have been in some earlier
release candaidates; this firmware therefore supercedes earlier RC's.


[New facilities]:

  1. Support WDS function

Please note that these facilities are not part of the official
product specification but it has been possible to include them
in firmware as a bonus for those users who might find them useful.

 - Correct large Fragment packet may cause Router reboot problem. 
 - Correct telnet command: adsl ppp parse error
 - Correct eMule + KAD will buffer leakage.
 - Wireless LAN Stability improved

[Known Issue]
  1. With IP Routing enabled, internal clients are not able to access 
     internal servers (e.g. web server) via the external WAN address of the router

[Hint]
1. If you have any ADSL on-line problem, please contact your service provide at first, 
   or get into web user interface ("Internet Access Setup" > "PPPoE/PPPoA" or "MPoA") to change 
   the "Modulation" of "DSL Modem Settings" to "T1.413", then to try again.  Also, you can use 
   the following Telnet commands to tune your router working with Globespan chipset DSLAM :

  > adsl status            Get DSLAM chipset verdor information
  > adsl dslam gspn        Set ADSL parameters compatible with the Globespan chipset DSLAM 
  > adsl dslam default     Set ADSL parameters to fatory default settings
