Right lets start off with some of the hardware involved:
Shaw BB50 Internet
Cisco DPC3825 Modem/Router
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)
Ive tried everything including taking all the hardware involved 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.
Sorry if its a bit confusing.
Thanks in advance for all the help.
