HELP ME PLEASE: MY TIME CAPSULE IS NO LONGER WORKING FOR ME

Question

Due to a recent move,  my Time Capsule doesn't seem to have the range & strength that it once did.
- A Local Internet Provider (MEDIACOM) installed their Router for our Internet/Internet Phone Service. 
- Due to the required use of the Provider's Router, I had to set my Time Capsule in "Bridge Mode" to function. 
- Although my computer can recognize BOTH (MEDIACOM & my Time Capsule) networks, I select & use my Time Capsule for my Home Wireless Network. 
- It seems to me, that in "Bridge Mode" my Time Capsule doesn't have the range & strength that it once did. For whatever the reason, I need to increase my Wireless range. 
- I ONLY use the Wireless WiFi (My Home Network) to access my e-mail/Internet from my iMac or IPAD.  All "other" Internet access (streaming) is done through my TV system, which is hard wired to the Internet.  Again, the Internet is hard-wired and directly connected to the TV's receiver. Thus, there isn't a huge demand for my Wireless Home Network. It's also password protected so nobody else is using it.
- I will admit that I'm now in a much bigger house (about twice as big as the previous home).  Also, I usually have to access it on the opposite end of the house.
How do I extend my Wireless range? Any suggestions, How To's, or useful websites would be most appreciated. In other words, what hardware do I need to purchase & how do I set it up?  My Tech knowledge is very limited. I think the solution will need to also be wireless because the distance is to great for ETHERNET.  That is, unless I can use what is already wired into my home.  For example, I'm told there is a CAT 5 Access point (whatever that is) very near the vicinity of where I need wireless access.  Would the purchase of another Time Capsule potentially solve my problem?

It must have the same strength it always had. .but the new environment blocks or absorbs wifi.. some houses are like a black hole.. nothing gets out.

Being in bridge or being in router mode makes no difference whatsoever to wireless output.. however range is affected dramatically by environment and perhaps by operating next to a much higher wireless power device in the Mediacom router.

If I give you useful sites.. apple mods will delete my posts.. so you should google yourself for "extend lan"
  That is, unless I can use what is already wired into my home.  For example, I'm told there is a CAT 5 Access point (whatever that is) very near the vicinity of where I need wireless access. 
This is the best method.. you do not need another TC.. plug the existing one into the Cat5 access point on the wall.. plug the other end into any LAN Port on the Mediacom router.. and as long as the cable is in good condition it will work great.
Make sure you are doing the setup correctly.
You bridge the TC.
You also create a wireless network.. it can be the same name as the mediacom router or different .. that is up to you. You do not attempt to extend the wireless.. this is most important.
Try it now.. all you need is a patch cord or two.
