Add a dial string to windows mobile 6.5 DUN

Published by:

When connecting windows mobile 6.5 to the internet via bluetooth dail-up and gprs (edge or 3G), you’ll notice that their aren’t any andvanced modem settings available anymore.

Establishing a connection just by dialing *99# is impossible, you’ll get ” The answering modem has disconnected “. You’ll need to add a dial string to include at least the APN information.

To enter a dial string now requires the use of a registry editor. You can find a good one here

To enter the dial string, you’ll have to edit registry-entry “1” in HKLM/Drivers/Unimodem/Init
change it to : AT+CGDCONT=1,”IP”,”web.be”
“web.be” is the APN name (ISP).

You can then safely connect using just dialing *99#

BBox2 Sagem Blocked – NAT out failed First packet in connection is not a SYN packet

Published by:

Sometimes a Belgacom Modem Sagem 3464 ( BBox 2 ) may block all outgoing traffic on any port except for port 80. You’ll get all sorts of errors from VPN clients, Bittorrent clients, and non port 80 wibsites. Typicaly the errors complain about being unable to connect. Also, the router will block all NAT and Server incomming traffic as well.

In the security log ( firewal -> security log ) you’ll find entries like these:

According to many internet forum posts this can only be solved by rebooting the modem, but there is another, quicker and better solution, especially when you don’t want to reboot the modem.

To quickly resolve this issue without rebooting ( thus without disrupting services like streams, uploads, etc. too long — rebooting takes minutes, while this solution takes less then a second) telnet to the Sagem modem, enter username: admin and password: BGCVDSL2
at the command prompt type:

fw_restart

Add_New_Post_‹_WWWalter_—_WordPress_-_ChromePlus-2010-10-24_14.33.45

Close the telnet session. You’ll now be able to connect to other ports and NAT functionality will be restored.

There is no permanent fix.

Sagem error Only one WAN connection can be enslaved by each bridge : Resolved

Published by:

sgmSymptoms: You want to change IP settings, change IP address ( local Ip address, default 192.168.1.1 ) but Sagem router returns a message: “Only one WAN connection can be enslaved by each bridge

Reason: Other VLAN interfaces are enabled and should be disabled when changing the LAN settings.

Solution: You do not need VLAN , so disable the VLAN circuits

– Go to advanced settings
– Choose Network Interfaces
– Click on LAN Bridge
– Click on settings (button)
– Disable the Wan ethoa0 … 12 ( disable everything exept LAN Ethernet en LAN Wireless – first and last ).

sgm

– Now you can change your LAN IP settings.
– Eventually return the state of the disabled interfaces ( only if required )

The Sagem 3464 is a (wireless) VDSL2 broadband internet router. It’s used by Belgacom, EDPNET, and maybe other providers using VDSL2 in Belgium.

Connect to the Sagem via a crossed UTP/STP cable into the Yellow port on the back of the unit (next to the power switch). The default IP is 192.168.1.1 Alternatively connect both router and PC to a hub or switch. ( Mind the unit’s DHCP server is active by default. )

My 2 cents on HTPC media PC and DVB

Published by:

Some time ago I decided to build myself a HTPC with satellite receiver. I ended up with this hardware:
Gigabyte Motherboard GA-MA785GT-UD3H , AMD PHENOM II X2 (processor), Cinergy S2 PCI HD (dvb card), Corsair DDR 1600Mhz 8-8-8-24 memory. I’m quite happy with it, but I like to share a few insights that I gained since then.

1. Don’t buy an AMD chipset.
I’m not saying AMD is bad. AMD actually is great. But the motherboard comes with an integrated AMD chipset including an integrated ATI video card ( 4600 ). This motherboard has all features to watch TV and Video, don’t get me wrong, but you won’t get any acceleration. Not in Windows that is. ATI is less open to the open source community and as I’m using XBMC to watch video, which uses FFMPEG to decode the video, all decoding will be done by the processor. The X2 ADM can cope only just. ( 55% CPU ). I ended up buying an NVIDIA ( GeForce GTX 260 ) which is affordable and gives me hardware acceleration in ( the latest beta ) of XBMC. As an added bonus I can play GTA with all settings at highest, 40+ fps.

2. Don’t buy Cinergy S2 PCI HD.
This card is stable as a rock and gives average to good picture quality. It’s compatible with DVBviewer Pro. But the remote control doesn’t work for me ( can’t figure out how to configure it ), but more troublesome: the card generates a high pitched sound ( like an old CRT television set ) when tuning to HD channels. It gives me a headache. I’m going to try and find myself a Hauppauge WinTV HVR-4000 00 DVB-S/-S2/-T/analog on of these days.

3. Software: DVBViever Pro
I learned there is a lot of DVB software, but it’s expensive, can’t handle plugins or is just crap. I stayed with DVBViewer Pro which is just perfect.

Some features I find very exiting are:

  • Can handle plugins, needed to access the subscription card of you got no conditional access module.
  • I can run as a service in the background, recording following a schedule
  • It can wake-up the computer to record a tv show
  • It can share the DVB card over the network so you can watch satellite tv on your laptop. It’s very easy and stable too!

4. Software: XBMC
For watching movies and MPEG4 or DIVX mkv or avi files, I got hooked on XBMC. It is by far the sleekest home theater software out there and it’s FREE. It supports many skins and can play almost everything. One of the coolest features is the ability to change synchronization of audio and video while playing a movie!! They are in the process of incorporating DVB receivers too. XBMC will also lookup your movie files and tv-shows in a few online databases, returning fan art and titles. The library is very comprehensive.

PS: Windows 7 is working great on this system, but try to keep it clean. Do not install to many things, as it will inevitably make your computer slow.

Media centers I tried but abandoned.

  • Mediaportal: I didn’t like the design, but It’s the second best FREE mediacenter out there.
  • Windows Media Center: Nice design, but it doesn’t show all files. Hard to get the library organised. Much like media player…
