Which 400mW is best - Atheros or Senao?

I'm looking for some input as to the best 400mW B/G card. I was considering the following:

NMP-8602 Senao A/B/G
ubiquiti sr2-80211BG Atheros based

What's the performance difference between the two? Any issues with either?

nmp-8602 is Atheros based too

SR2 is only b/g.

I would prefer SR2 between those 2, but I would prefer another card if i had choice.

Oh, I didn't realize the Senao is Atheros too. What do you recommend?

i've tested both of theme and the SR2 is far better than 8602.
The SR2 is the best minipci card ever for me - impressive sensityivity and power. Some guys claim that this great sensitivity can be disadvantage in high interference area - it is possible. The price of SR2 isn't advantage too :)

Rumor has it that there will be another choice by the end of 1Q2007.

Is your preference based on features or price or both?

I tryed the Senao cards, the first ones I got were ok. but the ones after that were nothing but truble. I only use the SR cards now.

I prefer Tonze 684HG and CM9 depends on the case.

P.S. Mostly on Price and the Maxim: I don't want to s**t o*f the ether.

I'm primarily concerned with stability and range for AP use. The extra cost of the SR2 is not a big deal for an AP. implementation.

The 8602 is unmitigated, unrelenting, unreliable crap.

It doesn't like cold, doesn't like work, doesn't like even the most minimial ESD.

It is a pathetic excuse for a wireless card.

If you ask nicely, I'll tell you how I REALLY feel about it. :evil:

We had to pull about 60 back out of the field so far and we are NOT amused.

On the other hand we do like Ubiquiti, but have found the extra power output is largely unnecessary in a well designed system unless you are talking about SR9s where alternatives are both scarce and expensive.

i agree..the nmp-8602s should be illegal.

never use them..ever.

Using the nmp-8602 in b-only mode has limited success, but as everyone else says unmitigated crap in 5ghz. These cards pop more often than any other radio I have tried!

Dear George,

Could you tell us how that card fare ?
And why you have to pull out them ?

Your information could help other mt user
from trying and get the same or worse problem from NMP8602

High Regards,
Andrei

We pulled a bunch because the just died. CM9s and various generations of MT atheros cards ran just fine in the same circumstances.

We pulled another bunch becuase they died at -14*C. CM9s will run fine well down into the -30s.

We finally pulled the rest because they like to start to reboot routerboards. You can drop the transmit power to reduce the problem, but frequently the rebooting comes back regardess of your efforts to stop it.

Replace the 8602 with a CM9 or R52 and everything is golden again.

We were never sure what was doing to go wrong next.

They are very, very, VERY bad news.

Ubiquity SR2 is definately a great card, I use them in all AP's now. The Senao 8602 is not a terrible card, IMO, but not as good as the SR2.

How many 8602s do you have in service Nickb? I thought they were fine to start with but the variation between batches was horrific.
