granted it is a cheap crapyp wireless card and a cheap router.
i tried telling her a better setup would probably do it. BUt she wants a wired setup. so im stuck running wire heh.
even though my router is on the frits. i keeps loseing connection and only works if i unplug and plug it back in. then it works for like 3 hours.
Then I'd say your problem is with the crap wireless card and cheap router. If you want a wireless network to function properly then spend the proper money on it.

For stranded cabling (like a jumper), if you get much beyond 100 feet, it's a crap shoot. The stranded conductors have a lot more loss. If one the NICs is weak, if there's a lot of electrical impulse noise, if the cable gets caught in the vacuum cleaner a couple times (etc) 100 feet can be too long.
FWIW

How in the heck is a cable going to get caught in a vacuum cleaner? Plain and simple, all network devices must adhere to the standard for that technology. If a NIC is weak? Are you for real? It's not a NIC limit, it's a cable limit.
The limit of Cat5 UTP is 100 meters. PERIOD. Now if you're running the cable near power lines or crap then that's another story. But you're spouting off crap that's just going to confuse the OP.

Sorry, but you are wrong; it's just not that cut-and-dried.
First, as Spidey mentioned, the guideline is for 90M solid core, 5M of stranded jumper at each end. Jumpers longer than 5M are, by the guidelines, out of spec.
Second, the EIA/TIA 568a/b "Rules" for structured cabling are guidelines that will ensure proper operation, if all components are compliant, without having to use lab-grade instruments to measure crosstalk, skew, attenuation per foot, a full-bandwidth frequency sweep (and some other tests).
The hard rule is to create a system that operates within a very specific envelope, and the only way to absolutely guarantee compliance is to run a qualified cetification scan.
Most consumers aren't willing to do that. However, many people have done 100 feet with jumpers and it's working to some degree; they're happy with that, in-spec or not.
When you are out-of-spec you will (more often than not, to some degree) surrender some performance; it's the trade-off for convenience.
I worked in a cable certification lab for years, this is the kind of stuff we tested.
The "vacuum cleaner" part came from seeing and hearing stories from homes and businesses about how they treat their data cabling. When it's stretched across the floor (a Very Bad Thing) it's subject to anything from secretarys rolling their chair across it repeatedly to the cleaning lady and her vacuum, to pets (ranging from cats and dogs to a variety of lizards) all doing their best to degrade the performance of otherwise decent cabling.
And finally, to round out the rant, the cabling has to be in good shape and be terminated properly (correct pair order, strain relief, twist maintained, etc). If the cable is stretched, severely bent (even once, even if re-straightened), twisted, crushed, knotted, chewed, or dryed out from exposure, or in a narrow conduit (and much more) it is technically out of spec, and performance is degraded to some degree.
