1)i cant connect to the interface of Thomson 585 v7... 2)i cant connect to the internet...it says that my pc cant get an ip

have you got two dhcp servers running ?
turn off dhcp server in wireless router
and use the one in the Thomson TWG850-4 Residential Voice Gateway.
make sure ip address in wireless router is different to the Thomson TWG850-4 Residential Voice Gateway. make it one higher on last digit of ip address
make sure dhcp does not lease out this ip address.

change subnet to 255.255.255.0 on every pc connected

check if the ip address that you are getting begins with 192.169.x.x ( x = any number between 1 to 254) check that your router the DHCP service is enable and that there a network range set (example lets say your gateway ip is 192.158.0.1 then your dhcp by defult in most cases will look like this ip range 192.168.0.2 - 192.168.0.254 using a netmask of 255.255.255.0 that will give you 254 ips per network.)

if your ip start with 192.169.x.x the that means that your machine is not getting a real ip assigned to it all you get is an APIPA that is just a reseved ip by the system to fill out ethernet interfaces that don't have and static ip or are in a network without a DHCP server.

you can set a static ip in the client pc if you don't want to enable DHCP in the router.

when you see Local Only message it means that your pc hasn't detected a route to the outside network ( internet ) without a proper gateway you will not be able to get to the internet, your router ip is always your gateway.

example:

Router Client pc

IP 192,168.0.1 IP 192.168.0.2
subnet mask 255.255.255.0 subnet mask 255.255.255.0
default gateway 192.168.0.1

you should try mac adress filter, that will do the job.

If the wireless security on the router is enabled, then the pre-shared key or encryption key on the router and PC should match.

To check the wireless settings, use the laptop to access the web interface of the router. Follow the steps below:

1 Using your Internet browser, go to http://dsldevice.lan or to the IP address of your router (by default: 192.168.1.254).
2 On the Home Network menu, click Wireless.
3 In the upper-right corner, click Details.
4 The wireless Access Point page appears. Under:
- Configuration, you can find the network name (SSID).
- Security, you can find the encryption.

On the PC wireless, access the wireless network connection. Select the SSID and then type the encryption key or pre-shared key.

Once the encryption key on the PC and router matches, then you should obtain an IP address and get online.

you lan driver reinstall

what u need to do is go to the interface of ur thomson speed touch through writing the ip address of that modem on the address bar of ur internet browser then go in that setup....Choose router instead of bridge.

HI
The following info. might help you fixing the above problem:

For WIRELESS CONNECTION follow these Steps:
(Note: Keep the Ethernet cable plugged in unless we set up
WIRELESS)
1: Click on Home Network
2: Wlan
Click on Configure which is the 3rd last icon on the Top
Make sure that the option-Interface Enabled is ticked.
Channel selection should be ob Manuall.
Wireless channel can be 11( thats what is in my case).
Encryption is again depending on what type of sercurity you wants. I would suggest go for WPA.
After editing the above info. do not fail to note the KEY before clicking Apply
Now just enable the WIRELESS CONNECTION on your PC /
Laptop,
Pull the SSID of your router and Click connect.
It will ask for the WEP/WPA key?
Enter the key and Click connect.
