Hp r033tx wifi

[Malav_2000]

I have a Hp R033tx which had  RT3290 wifi card and I replaced it with intel centrino n 2230 and it worked for me but only increased the speed slightly. I wanted to know if I can use a 5ghz card on my laptop. If someone knows or can suggest a good card which will give me good speed then please let me know. It worked with centrino card so I suppose it should work with other cards too!

One antenna or 2?

When I removed the old RT3290 it had only one antenna...by antenna you mean the wire connected to it right?

[Huffer]

Yes. Your laptop has no whitelist but having a single antenna greatly limits your options. Almost all 5ghz cards require 2 antennae. You can add one, but it is a major job.

Actually when I placed in centrino card I did place in 2 antennas which improved the range! I connected another antenna and routed the antenna on the other side as well! I do have 2 antennas and have made simple modifications to integrate one more...lemme clear one thing...placing 2 antennas means connecting a new one on the other side right? I don't have to make any modifications to the motherboard...right?

No modifications to the motherboard. Its the number of antenna leads connected to the card. Ideally, you would disassemble the laptop and route the second antenna next to the other one and then up the opposite side of the display housing. Sounds like you maybe even have 3 antenna leads. So yes you can install an 802.11ac 5ghz card. The best is this one:

Thanks a lot! That really did help me! And yes I opened the screen area and routed another antenna! And I'll soon post if I'm able to get 5ghz...thanks a lot!!!
