Last hope before I call a professional

Continue to have problem....
replaced router with Linksys WRT54 GX,(had previous WRT54 GX for over 2 years no problem, Linksys sent a free one to replace what they said was a defective router) signal still drops off after 60 feet. one Pc (2 years old) has Linksys WPC300N adapter other has integrated intel wireless G( 1 year old). Plus A new MBP. All notebooks have same problem. Need help solving this problem.
Should I switch to Airport Extreme(or other N router)? Would it work with the linksys WPC300N and integrated intel G, or will it slow down the network? I'm willing to buy an adapter to replace the intel wireless g if needed. I was under the impression that you need the same brand router and adapter to achieve best performance. thanks for any help....
Or should have a more knowledgable person come to my home and troubleshoot the problem...

 

If you are having problems with range, Install High Gain Antennas will help a lot. Most wireless routers only have 2 dbi, install 5+ dbi. Not sure you can change them on that MIMO router.

I no longer like linksys WRT54 series ever since Sisco started making major changes to their hardware with out changing there model numbers.

If you want a better performance, I would move to a stand along AP. I have a 54G (125mbps) that will cover my whole house on LOW power, while penetrating 4 walls. NOT USING MIMO. With a AP you will be able to position it so you get the best coverage, only need to run 1 cat5e to it. MIMO tech uses 2 channels (not all) so if you have other networks a round you will have problems. And you need matching cards for it to work.

 

Blue I'm not a total newbie but I would like a little more detail, you seem to be one of the most knowledgable posters when it comes to wireless. I am connecting via cable modem and need security. I have one desktop (no wireless card) and 3 notebooks, one is a Mac.
1-Are you saying that all I need is Access point and no router.
2-If so which access point and cards would you suggest

Thanks for your help

 

apes, you will still need a router to assign your multiple computers an IP address. the access point will be connected to the router via cat5 and will distribute a wireless signal in an area of the house that is lacking. This is a good solution as using a repeater will cut your bandwidth in that particular area of your house in half

 

Can the Access point be next to the router or would this defeat the purpose of buying an access point. If I need to locate the access point to central location I would need someone to come in and wire the cat5.

 

You can locate the AP next to the router. Being a seperate unit it will out preform a wireless router. Plus if you find out later on that you need to relocate it, then do so at that time. At the lease put the AP up High to get above items that can block your signal.

 

any interference? cordless phones etc?
