multiple routers slow down internet

Charter Cable wants to charge me a 2nd internet bill if I add a 2nd modem. I need 2 hardwire connections in my home. My fiance needs a hardwire connection because her work server disconnects with wifi (anyone, not just her, and the server people can't fix it). If she is hardwire connected, no problems. My home office is down the hall, and I have several older devices, including scanners and printers, that connect by hardwire ethernet to my PC. I actually have 3 routers for the network. Modem directly to LInksys 4 port router in her office, one cat 6 cable in the crawlspace from her office to my office, followed by a LInksys 1200E wireless router, then one cable to another Linksys 4 port wired router. All routers are 10/100. Charter gives us max 50 Mbps service, and direct to modem clocks in around 43, which is acceptable. My PC through all 3 routers slows speed down to about 4, around 10% of incoming speed. This is too slow. How can I increase speed for all devices closer to the 50 Mbps that Charter comes into the house with? I've heard that wired is almost always faster than wifi. Should I use a switch instead of a router? Is 10/100 not fast enough for 50 Mbps? Are the devices not configured properly or do I need new devices? Thanks.

A residential situation, even with a home office, rarely needs more than one router.

Incorrectly configured, it introduces all sorts of problems.

Modem/router -> switch -> multiple devices, incl Access Points if needed. Routers can bee turned into access points, but you have to do it correctly.
If you didn't setup a static ip and turn off DHCP on the other two routers, then it's going to cause problems. Only 1 router can be the DHCP server and if you plugged others in without configuring them to run in a multi-router setup, then yes, you will get slow downs, drop offs, discconectes, all kinds of problems.

If you don't need the additional wifi of the other routers, then yes, a switch would solve it all. If you want to use the routers, it can be done, just needs a bit of time and configure.

I'm too cheap to buy new switches but have extra gigabyte routers, so they are used as switches to extend my massive network, and add additional wireless access points. Mine are configured right though. I get 100mb/s from my ISP, and get about 95mb/s at the furthest point so pretty much no loss.

Last count with wired and wireless devices, we have 43 in the house.

You're about 2x mine. 20something devices, 50/50 FiOS, and pretty much full performance all over.

Update: only 1 router is wifi, 2 are wired. The first wired router had DCHP enabled, I just disabled it.

Most replies state that I should configure correctly, yet no one is suggesting how to do that. Where can I find instructions for correct configuration? I have found several online and followed those instructions. DCHP was a missed detail, thanks for that tip.

A lot depends on exactly what you need it to do.
