Multiple routers on one connection.

Dear people of Tom's Hardware,

I have a bit of a wifi problem. Two fairly big buildings use the same wifi through a chain of routers, and there is a loss of speed. The cable comes into the first router (Cisco EPC3928S EuroDocsis 3.0 2-PORT). Then there is around 10m-15m(meters) of ethernet going to router two(TL-WR841N). Then there is approximately 30m going to router 3(TL-WR940N) which is in the second building second floor. From that router, there's two cables going to the first floor, cable one around 10m(not important router[router 4]), and cable 2 35m(TL-MR3420[Router 5]). All this is used by around 15 devices so it shouldn't be too much.(laptops and phones)

So that's the grid. The internet package is 80mbps download speeds, and that was provided from router 3 quite well until we added router 5 into the grid. As i am writing this post, The speed is 25mbps(speedtest.net) and occasionally goes up to 40mbps.

Do you have any idea what i could do to boost the speeds? Are any routers in the grid bottlenecking the grid from full potential, if so which? Would it be better to have one cable for each router coming from the cisco? Would a better firmware change anything?

It would be really nice to have all 80mbps pumping throughout the whole grid.(In the near future, might upgrade to 120mbps.)

Thank you.
 
You need to run these devices as AP not routers. Generally that means plugging the lan ports together and not using the wan.

When you do this the router is acting more as a switch that also has wireless interfaces. You want to test from a wired port. If it is a wireless issue check to be sure the devices do not overlap channels on the AP that are close. If they are fairly close the AP may have options to reduce the transmit power which would reduce the signal that bleeds over into the other area.
 


Will test and see what happens. Thanks
