Because the house is constructed of cement and rebar the wireless signal is blocked in all but one room...I had a cable 20meters long made with 5e catagory cable with 8 pin connectors {a long patch cord if you will}. My two meter cord works great, the 20 meter keeps saying "unplugged" what is the most distance I can run? Any advice greatly appreciated!!

20M is well in the normal range for direct connect or 10M for a patch cable check your wiring diagrams against this:
http://www.networktechinc.com/standard.html
TIA/EIA 568A this is the industry standard.
But TIA/EIA 568B is used in CAT5e to reduce crosstalk.
Category 5e
Cat 5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. It was formally defined in 1973 in the TIA/EIA-568-B standard, which no longer recognizes the original Cat 5 specification. Although 1000BASE-T was designed for use with Cat 5 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BASE-T. Despite the stricter performance specifications, Cat 5e cable does not enable longer cable distances for Ethernet networks: cables are still limited to a maximum of 100m (328ft) in length (normal practice is to limit fixed ("horizontal") cables to 90m to allow for up to 5m of patch cable at each end). Cat 5e cable performance characteristics and test methods are defined in TIA/EIA-568-B.2-2001.
For Solid UTP:
Fast Ethernet 100baseT 100 Meters (328 feet)
Twisted Pair Ethernet 10baseT 100 Meters (328 feet)
Recommended maximum lengths for Patch Cables made from stranded cable:
Fast Ethernet 100baseT 10 Meters (33 feet)
Twisted Pair Ethernet 10baseT 10 Meters (33 feet)
Hope this helps

Why make up a cable, they are quite cheap to buy. You have either got an incorrect cable sequence or a bad crimp. They are quite difficult to get right, you really need a lan cable tester for these jobs. You do NOT need any special wiring for distance, it is exactly the same. 150 meters is the quoted CAT5E range, I have seen 250 meters work.

Chances are the cable is simply badly made . . . Cat5e should run to 50m+ with no problems
Also compare the end plugs on teh 2 cables, is 1 patch (all cables in same order) and 1 a crossover (not same order in 2 plugs) ?

You wired it wrong, for that distant, you cant just use straight 8 to 8, theres a special wiring layout for it, not at work now so I dont have the diagram in front of me, but from your description, thats the cause of the 'unplugged' error.
Seen that, got a T-shirt for 'Wasted a whole day on a single cable' :)

Hmmm.. That shouldnt be too long. Ive got a good 100ft etween my router ond one of my pc's. Maybe the dsl modem isnt strong enough to push it that far? Mine goes through the modem to a linksys router to my pc.

Must be bad ends or damaged cable. Ethernet can run to hundreds of feet without error (even further than their specified lengths)

20 meters is nothing. You should be able to go 300 meters before you have any signal degradation.
