[SOLVE]DTHOMSON TG789vn and Raspberry Pi

[Funkigamoses]

Hello! I can connect to my cell phones wi-fi and get access to the internet, but when I connect to my router, it won't let me out on the net. It says that it's connected but it won't download updates or get on google. When I checked my router it says that the raspberry pi is "inactive".

I have very little knowledge of networks, though, I really want to learn more, but I feel a bit "stupid" posting these threads. I haven't seen any posts about the Thomson router here.

It would help if we didn't have to guess so much!

For a start, are you trying to connect your RPi to your router by WiFi or wired ethernet?

I am trying to connect through wireless.


Here is some more info from my pi:

inet addr 169.254.223.162

Bcast 169.254.255.255

mask 255.255.0.0

gateway: 0.0.0.0

destination 169.254.0.0

169.254.xxx.xxx/16 is a special address range known as the link-local, it's not routable.

Change your settings to use DHCP and see what address range your router assigns, I can guarantee it won't be 169.254.xxx.xxx/16. It'll probably be 192.168.xxx.xxx/24 or 172.[16-31].xxx.xxx/16 or 10.xxx.xxx.xxx/8.

You could look at your laptop and see what address has been assigned to it.

Do not assign a static address from the DHCP address block that your router uses, it could cause trouble later.

I wasn't expecting much progress on this problem before viewtopic.php?p=791682#p791682 is sorted.

Alright, I found my router gives my pi the adress 192.168.1.86. Should i do the sudo nano /etc/network/interface and give the wlan0 the static setting?

Not sure what you mean? Do you mean the router gives your RPi that address if you connect with ethernet cable?

If you mean the router gives the RPi that address when not connected by ethernet, then it is connected OK by WiFi and you should have nothing more to do.

You need to look at the DHCP pool of addresses used by your router.

If the pool is 192.168.1.1 to 192.168.1.100 then pick a static address from 192.168.1.101 to 192.168.1.254 (outside the pool).

Ok

Now I have:

iface wlan0 inet static
adress 192.168.1.254
netmask 255.255.255.0
gateway 192.168.1.1


It still does not work...

[drgeoff]

Ok

Now I have:

iface wlan0 inet static
adress 192.168.1.254
netmask 255.255.255.0
gateway 192.168.1.1


It still does not work...

Unless you have changed it (and I doubt you know how to) the default IP address of your Thomson router is 192.168.1.254. So giving that same address to your RPi will never work properly.

There is no good reason for you to be giving your RPi a static IP address. DHCP works just fine and is pefectably suitable. When you have more experience with networking you can think about using static.

However if you insist on using static now use 192.168.1.254 for the gateway. The router manual does not seem to say what the DHCP pool range is. Try 192.168.1.63 as a static IP for your RPi.

Well, my router have assigned a static ip adress for my pi, and that is a problem. Should I assign the adress my router have chosen to be the static adress of my pi?

Ok

Now I have:

iface wlan0 inet static
adress 192.168.1.254
netmask 255.255.255.0
gateway 192.168.1.1

Is that a copy/paste error, or have you really put "adress"?

[drgeoff]

Ok

Now I have:

iface wlan0 inet static
adress 192.168.1.254
netmask 255.255.255.0

A router will NEVER assign a static IP address to your RPi or any other device. A router only assigns DHCP addresses and ONLY when the device (your RPi) asks it to. A static IP address is ALWAYS assigned by setting it on the device.

If the router has assigned an address it is not static and it is from the router's pool. You should never use an address from a DHCP pool as a static address.

So where is the 86 address coming from? If you have not set that on the RPi and the RPi's only connection is WiFi then the 86 address is a DHCP address from the router by WiFI and your RPi is connected.

Solved it! I entered dhcp in the network/interfaces, and I thought that the gui would change showing the icon "connecting" so to say.
