Help fix my internet
 

Right lets start off with some of the hardware involved:

Shaw BB50 Internet

Cisco DPC3825 Modem/Router from shaw
Linksys E2500 Router
TP Link something x2

The problem i am getting is that the Cisco is not giving internet access to the Linksys. I have the Cisco located in the basement, with 2 ethernet ports being used; one to the Linksys upstairs, one to the TP Link (1) on the ground floor. Everything was working at this point.

Today i tried to add another TP Link(2) to the Cisco for my basement suite's WiFi. Something went horribly wrong and now it refuses to give any internet to the Linksys. The TP Link (2) has since been removed and the TP Link (1) is functioning properly.

If i bypass the Linksys and go from the Cisco to my computer itself using ethernet cable, internet works but is choppy (says that there is no connection at random then connects again repeats 3-4x)

Ive tried everything including taking everything and putting them infront of a fan for half an hour. The cisco simply refuses to give the linksys internet.

I googled it and found a bunch of stuff on mac addresses and played around with that too. I think i messed it up so i pressed the reset buttons on every device.

Sorry if its a bit confusing. :okay:

Im thinking thats its 3 possibilities:
-Cisco shaw router/modem thing broken
-Linksys e2500 broken
-Ethernet cable that runs from one end of my house to another is broken.

Thanks in advance for all the help.

ethernet cable's don't just break
it's very likely a setting/configuration
are TP-link routers or switches?
you could try going into the admin page of the Cisco gateway and put the Linksys under DMZ mode

I would suggest powerline ethernet.. 1 goes into the shaw modem, other powerline you can plug anywhere that has a power outlet and use up 16 units... pretty much no configuring as they are plug and play and no more cables...

Are both the Cisco and Linksys running as routers? Only one of them should be running DHCP. Personally, I would disable DHCP on the Linksys, and make sure it's connected to the Cisco via one of the LAN ports and not the WAN.

You need 3 wireless routers in your house?? It must be massive to need that sort of coverage.

Call shaw. Make sure your Cisco is set to Bridge mode. This will disable all routing/wireless features on it since you don't need them. Then all 3 of your routers can be configured independently via their own config pages.

Well one router is at one end of the house and the other is at the other end of the house so there are some weak spots around. Shaw said the Cisco was already in bridge mode so it must've been something wrong with router settings

This man knows what hes talking bout :fullofwin:

IM FIXED :awwyeah:

Thanks for all the helps guys
