Is Wireless in 4.x and N reliable?

Wed Oct 20, 2010 3:59 am

Hello

I had a perfectly stable 3.30 link running with a -60 in A mode that could pull 25mbit no problems

I changed to a N card and 4.11 thinking I can go faster.

Speed is OK but it disconnects ever few hours for a couple of seconds, says not polled too long, Ive change HW retries to 15 and turn of periodic calibration with no luck.

Is this a v4.11 problem or an N problem?

Thanks

:-)

if you get disconnects in v4, adjust the hw-retries time

You got alignment issues then, when i switched from 3.10 wireless to 3.30 wireless-test (the same of 4.x) i lost some user links..
When i investigated on them, all of them had some obstacles between or bad fresnel..
If you need a good link, fix them with a good installation, following some simple rules. Then you can play with software settings...
Old wireless module was less sensible, but the quality was lower than the newer one..
to the other side, NV2 is more stable on trouble links than normal nstreme, but it's still beta, use at your own risk.

Hello

Is this a v4.11 problem or an N problem?
It's probably a "you" problem. :) My 802.11n works relatively well.

N works well-ish in 4.11 and the 5.0 beta. I will say that (for whatever reason) that you should expect to achieve a slightly less stable CCQ (i.e., 90%+ rather than solid 100%) with 802.11n than 802.11a but I do not know if that is related to ROS or just the nature of 802.11n.

Thanks

This link is 500meters, I can see the other side and signal is perfect (-60)

I think it's v4, if I downgrade teh link is stable, put v4 on and its disconnects twice a day or so.

Perhaps v4 is faster in the lab, but it's definitely more sensitive imho.

I just find it funny that the OP says he changed the HW retries then normis replies by saying adjust HW retries.. LOL
