Speed IP Webcam

Hello,

I'm considering to acquire an wireless IP Webcam.
One opportunity is a Webcam that only works in Wireless Network Mode B only.
My router is a WRT54GS with Thibor 15b3.

My question is the following : Is this B-only Webcam going to slow down the whole wireless network or will the 2 protocols (B and G) be managed together by the router ?

Thanks

 

If you use a B wireless device, the router will function with both devices at their respective speeds.

The B and G devices both operate in the same frequency range and WILL cause marginal slowdowns. However, the same holds true if you have multiple G only or B only devices. It should not be a difference that is noticible enough that you need to be concerned about, however.

 

Thanks a lot.
The guy at the store had no idea and placed himself on the safe side saying that it would restrict the whole network to 11 mb/s.

Thanks a lot.

 

Hello,

I'm now trying to use DDNS to have an easy access to the camera that I may connect in future.
What I see is that WRT54GS considers that its IP address is 10.0.0.1 which is, in fact the address on which my ADSL modem (Alcatel Speedtouch 510) sends everything. The real address is obviously different (and dynamic).

Could anyone tell me how to have WRT54GS picking up the IP address on the Internet side ? I've tried to search on the forum but did not find a explanation that I understand.

Thanks.

 

just open account on some dyndns service

input account data into router setup and hola

Hyperwrt 15C supports Dyndns.com, Zoneedit, and TZO.com. Pick one of these and open an account there. You will pick your username, password, and a domain name (ie myname.dyndns.com, etc.).

You will go into your router setup on the DDNS tab, select the correct DDNS provider, and enter the required information (username, password, domain).

You should be able to access your camera remotely by going into your web browser and selecting myname.dyndns.comort where the port is the port you have set up in the camera for its web server. You may also need to redirect a port on the router to access the camera, depending on the model and setup.

 

Thanks to both of you.

I already did what you say. The problem is that the IP address sent by WRT54GS to Dyndns.org is 10.0.0.1 which is the address given by my ADSL modem (Alcatel Speedtouch 510) to WRT54GS.

What I need is how to have WRT54GS to detect the real internet address given by my provider (Skynet in Belgium) to this Alcatel modem.

Thanks.

 

the WRT will report the address it gets on the WAN interface, so you will need to put your modem in bridged mode.

Hello again,

Thanks for the help.
Now I've put the modem in bridged ethernet mode and the router in PPOe.
Works great and the DDNS service also.

However, a new minor problem appeared : I can't access the modem config page anymore (http://10.0.0.138).
How do I do to get the fonction back ?

Thanks.

 

OK, thanks.

This is far from my competences. I'll make some search in case but I'll probably give up. If I need to administer the modem, I can always switch the router to "automatic cobfiguration - DHCP" for a few minutes.

Thanks to all of you folks. All this is quite fun !

 

Actually you can administer the modem, but you need to add a route to it manually through the CLI.

example, if your modem uses 10.0.0.1 as it IP:

Code:

iptables -I POSTROUTING -t nat -o vlan1 -d 10.0.0.0/30 -j MASQUERADE 
ip addr add 10.0.0.2/30 dev vlan1 brd +

That /30 netmask would leave two host addresses, .1 and .2. Depending on your modems default IP, you may have to adjust the netmask down to 29 or 28, or you could just go with 24 to include the entire 3rd octet.

Thanks a lot !
It works great !

Last question : I've tried to put the 2 command lines in the startup script and have put Telnet Daemon to start automatically at startup. This does not work.
Any additional trick to get it working ?

Again, Thanks to grcore

 

add those commands to firewall_script instead of startup script.

OK, it works great !
Thanks a lot.

Is there a website or a threat where I could learn the basics for ip tables commands ? It is great, sounds fun and I'll like to learn a bit about it.

Thanks.
