my computer is all confused with connections

I was trying to reinstall vista-x64 onto my laptop, and I updated the intel wifi driver. Unfortunately I also changed the security from 64 bit 10 hex to 128 bit 26 hex on my network. The ensuing result is that my laptop is now having LOTS of problems because it's picking up 3 different "networks" from my router and I have to manually choose which one to go with. How do I tell the router to just send out the 128 bit 26 hex and to STOP sending out all the other false signals?

My second problem is that my laptop cannot remember for the life of it the key for the linksys router, Every so often it requires that i retype in the name of the network and the key to it... I don't know if it's because of something I did, but it's becoming increasingly aggravating that every time I try to go wifi it asks me to log in as if i'm a complete outsider. How do I reverse this? (having to remember a sequence of 26 numbers and letters is NOT fun.) Is there something in the linksys router I can reverse so that it automatically goes to the right connection, the first time, every time like it did before I reformatted?

Edited to add: The Linksys_SES_8281 and Linksys_SES_8281 2 are using the same radio and SSID, but i want to get rid of the one that doesn't work (the latter, SES_8281 2) because it's annoying to have to manually choose it. What should I do?

well..... bring it back to the normal set up
bottomline, i don't think it's the computer, i think it's how you set up your router, something went wrong or became complicated

 

I just did a hard reset, that reset it, but now you have to set it manually every time it starts up.
