Cisco 1841 - Talk Talk Configuration

Hi All,

Hoping you can help. I have recently replaced a terrible ISP router with a Cisco 1841 router which seems configured correctly however ever since connecting this up I am having very weird internet issues.. 

 

For example when trying to browse a webpage it will give me "page cannot be displayed" however if I try a few times it loads but not correctly - However if i get the website to load correctly after a good few times it then seems to load OK (As if it is cached) but as soon as I go on a webpage I have not used it either slow or "page cannot be displayed"

 

I tried plugging my technicolour router back in and I get normal internet again. Please see below the config and advise me if anything is incorrect. The internet is that intermittent I have had to plug the Technicolour back in until I get a resolve.

 

I have DNS / DHCP running on a Domain controller - The router is simply the default gateway & the device my ADSL plugs into.

I have also tried plugging direct into fa0/0 (Which is where the Fortinet device sits) and giving myself a static IP and I still get a kind of intermittent Internet connection, which is cleared up if I plug in the router provided by talk talk.


 


I suspect I have a config error somewhere however the router is not providing any feedback so your feedback would be great.


 


thanks

After banging my head on every wall in the house and having my father patch up the plastering I finally found a configuration that works with Talk Talk if you opt to use a Cisco router. The configuration is below - I have *** the personal config which will need replacing with your configuration.

 

I am even kind enough to provide you with a MOTD :D

Ignore the IP NAT Statements - They are an example incase they are needed - I use these for Exchange Server.
 
This also has no DHCP configured as I am running DHCP separate. If you require DHCP you will need to add this by running the command
 
IP dhcp pool *DHCP POOL Name" IP Address, Subnet mask

Glad you got it sorted, by talking to yourself! :D

 

I'm no use, as I never deal with Cisco kit....

Yeah there is no guide out there that helps with Talk Talk and Cisco Kit that works... I thought by posting on here the configuration that actually works it should be a high traffic post :)
