Windows 7: How to use a ADSL modem's wifi with a fiber connection.

How to use a ADSL modem's wifi with a fiber connection.

Hello everyone,
I'm trying to achieve something which I think most might not have tried,
starting with what I have

1.Type 2 adsl2+ cpe/iad modem-It has built in wifi.
2.A fiber internet connection.
3.A samsung smart tv with built in lan adapter (40 inch LED-no wifi but wifi ready)

Now the modem which I have mentioned above cannot be used with the fiber internet connection.So,it is just lying waste but I want to use my internet connection provided by my ISP through fiber connection with the modem so that I can use my modem's wifi and lan ports.

What I have done was connected my laptop to my modem's wifi and also to my ISP's fiber connection so my laptop is connected to both the networks and now I have tried to establish a bridge connection between the lan connection and the wifi connection I was successful and I was also able to share my internet connection(as shown in my laptop) but when I have checked for the wifi internet connection it is not there(Checked on my mobile-one x and ipad).

So is there any way so that I can do this...??Please don't suggest me to use a application like connectify or virtual router to share my fiber internet connection.

Now there is a another thing that i have mentioned above my Samsung tv now I have connected one of my modem's lan connection to my tv and tried to use the all share application(my laptop is connected to the same modem through wifi) in my laptop I have found my tv and the laptop connected to the modem(Control Panel\Network and Internet\Network Map)but my tv is not at all recognizing my laptop and my laptop is also not finding my tv(in the allshare application).

If my first problem of getting my internet to the modem's wifi is possible then I also want to try that for the modem's lan connection so that I can avoid the pain of buying a samsung wifi dongle which costs more than 10% of my tv's price.

This is my first post in this form pls give your suggestions if I have gone wrong any where.

the answer is YES

you piggy-back the router onto the fibre modem, you can do this if

a) the fibre modem has a LAN port (which it will have)
b) the fibre modem allows its IP range to be changed
c) the spare router allows DHCP to be disabled
d) the spare router allows its LAN IP Address to be changed

if yes to all 4 then you can do this.

you simply shorten the Fibre Modems LAN Range by 1,
e.g. (assuming your Fibre Modem is on change - to -
as the device is on 0.1 and the rest of the range starts from 0.3 to 0.254 , this leaves 0.2 for the 2nd router to use...

(if your fibre modem is on and range is - then follow suit by changing the to and using the for the 2nd router)

now once you done the above in the fibre modem you can turn off any wi-fi in the fibre modem ...assuming it has any.

now unplug the fibre modem and plug in the 2nd router, log in, disable DHCP and set its LAN IP Address (not the range) to the address you free'd up previously... e.g. (or then apply & save - you will now use that IP Address to access this router instead of

now with both unplugged and powered down/off, plug in the Fibre Modem and turn it on, give it time to connect to internet, then plug a LAN cable from one of its LAN ports to any of the 2nd routers LAN ports, plug in and turn on the 2nd router and wait for a while - you should now be able to use its LAN ports and its Wi-Fi connection :)

EDIT: as far as im aware its possible to have the 2nd routers IP Address both INSIDE or OUTSIDE (this method) the DHCP Range of the first modem/router, ive seen advice where both have worked.

as for your TV, it sounds like you are trying to Network them together so you can browse/watch files on your TV from your laptop..right? - your TV would have instructions on how to do this if it uses a specific utility/app supplied with the TV, but normally you would have Homegroup running in Windows 7 and this is what networks the computers together, you would then enable sharing on the folders you want too access via the TV, so in laptop right-click on folder (root folder would give access to all folders and files within) , choose PROPERTIES, then SHARING then ADVANCED SHARING and check 'SHARE THIS FOLDER' and click OK - now any computer connected to the router/network via LAN or WIFI can access this folder by accessing the NETWORK link in Start Menu and using the Homegroup password when prompted - but your TV is specific and will/should have its own instructions, disable password on laptops homegroup, this will make it easier.

My fiber modem is not accessiable.My ISP has a set up box which has 8ports.I was given one of those ports the fiber modem is inside the setup box which is not accessiable......

So is there any alternative way and do you know why the bridging technique didn't work....???

And coming back to my tv I have to use all share application in my laptop to access my hdd media files in my tv I have tried that I have connected my spare modems LAN to the tv and my laptop to its wifi but it's not working I tried to do the same using my other laptop instead of my tv then it worked fine but it's not working with the tv and I have enabled home sharing all other options...

- and have you made folders accessible? (sharing the folders so other computers are allowed access to them)
- is this ALL SHARE application something your TV uses also?
- does your TV use Ethernet in the manner your trying to use it? -it may just use ethernet to access internet but not actually see and access other devices on the network.

it could be that HOMEGROUP is getting in the way? perhaps the TV does not recognise this service, it may help if you disable the password

you should still be able to piggy back the spare router onto the Fibre Modem because as far as im aware it works both ways...when the 2nd router is both inside OR outside the range of the DHCP of the first router - this means you could just set the 2nd routers IP to and turn off DHCP and it should still work (this is assuming both routers use 192.168.0 range - if first fibre modem uses or to access it then you will need to change the spare routers IP to the difference here is making sure the first 3 lots of digits match the fibre modems first 3 lots of digits , broadcast range (which is always same range you access its interface on - e.g. if you access your router on then it would mean its broadcasting to , so your spare router would need its IP changed to , 200 is a nice high even number thats easy to remember and your unlikely to have 199 other devices connected all at same time

so.... turn off your fibre modem (so I know your not connected to it, even by wifi) - then plug in and turn on your 2nd router - enable the wifi, turn off DHCP and change its IP ADDRESS so first 3 lots of digits match your fibre modem and last lot of digits is 200 (e.g. - apply/save these settings and unplug and turn off the router (important) - now plug in the fibre modem, give it time to connect to internet, then plug a lan cable from it to the 2nd router (any port) and then turn it on - after that you should be able to use the 2nd router by LAN or WIFI - what happens is the fibre modem assigns devices IP Addresses when connected via 2nd router because DHCP is off its passed through to the Fibre Modem as it is the primary DHCP server...

if your fibre modem is a BT Openreach one (UK) you can install hacked firmware which allows access
