Hi,
As i write in this post i've send back my n9 to vendor 'cause I think 802.11n problem is due to hardware. so, I only write here for your information ...
As many N9 users I know that I'll have to "bidouille"/hack it to have the best phone ever, but, if something like wifi donesn't work properly ...
It was very difficult to manage my email account, update mail box (only headers), read mail and get SIP account working over wifi ...
I didn't read anything about any link between screen lock and wifi but, in my test to make it work i used ping (ping -t rm696) rm696 is default dns name of n9 on my local network.
ping lost many packets, until my n9 get in "spleep mode" (screen locked after few seconds) and suddenly all pings came back ! I Unlocked phone and again, ping get lost, I locked screen and ping came back !
Of course, as I was running these experiments, all my mails were downloaded, my SIP account connected and so on ! but of course, unable to download mail content when screen is on and SIP get in netwok search mode
Of course, in connection manager, wifi appear to be connected with good signal strength.
I use 300mb/s 802.11n network with wmm active on a netgear wnap320
I really think it's a hardware problem due to screen.

Smells like screen taking up too much CPU and network dropping in lower CPU usage priortiy...
As if it would be hardware, locking the screen would not necessarily fix the issue...
But interesting topic!! I have had problems with Wifi too (apart of the usual bugs). It would be *great* to improve this!
Please don't give up!

ok, but do you have problem with 802.11n wifi.
I successfully get my n9 work on 802.11g access point but once at home, with 300mb/s 802.11n, like many users on this post, connection was unusable...
what is your wifi class ?
[edit] sorry, I didn't see you are author of post ... your N9 seems to work better than mine on 11n wifi.

But I know that some other N9 users said they had no problems with their 802.11n routers.. maybe in neighbour topics on this forum. Can somebody evaluate actual Wi-Fi N speed in a similar way and post the results here so that we can compare different users' experience?
P.S. "M/s" means "Megabytes per a second" - it's not a bitrate, it's a real file transfer speed.
Not a good wifi benchmark per se, but it gives some idea about the relative performance. N9's 802.11n peaks at about 4.3 MB/s. The wifi signal isn't the best possible (router next room, behind a wall) and seems to affect n9's wifi performance more compared to a laptop using g standard wifi, which is slower but gives more consistent readings.

Some good news.
Before trying to recompile wireless driver or going to NITdroid forum I decided to reflash my Nokia N9. You see, many errors and misconfiguration problems are possible due to updating the phone over the air several times, so it's certainly better to make a "clean install" of phone firmware. So I followed these instructions to zeroize and reflash my N9: http://talk.maemo.org/showpost.php?p...16&postcount=1 .
Then I turned on my phone, installed developer-mode, networking utilities (including wget), and redone all my measurments.
First I set up AP configuration with QoS disabled; here is a part of my hostapd config:
I tried to download a large file and the average speed was ~ 2.6 M/s (according to wget output). It seemed to be usual 802.11g speed.Code:hw_mode=g ieee80211n=1 ht_capab=[HT20+][SHORT-GI-20] channel=6
Then I edited hostapd config and enabled QoS:
The result was exciting. Enabling QoS improved the speed, not reduced it. The average speed was ~ 2.9 M/s. Sometimes it jumped up to 3.1 M/s (!). Such a result is unreachable with 802.11g-only mode.Code:ieee80211n=1 wmm_enabled=1 ht_capab=[HT20+][SHORT-GI-20] channel=6
Okay, then I made hostapd use [HT40+] instead of [HT20+]. The speed reduced. It was ~ 1 M/s again. With QoS disabled it raised up to stable 2.6 M/s . And such a result isn't surprising, because according to iw output, N9's wireless module supports only HT20 and SHORT-GI-20 capabilities, so using QoS with HT40 results in reducing speed. I think it's quite normal.
But at least I've managed to get my 802.11n work properly with HT20 and QoS enabled. The speed is 2.9 - 3.1 M/s now (it's definetely higher than usual 802.11g speed), the connection is stable, so I'm able to use Internet, ssh and http file transfer without any problems. I'm very glad.
But I know that some other N9 users said they had no problems with their 802.11n routers.. maybe in neighbour topics on this forum. Can somebody evaluate actual Wi-Fi N speed in a similar way and post the results here so that we can compare different users' experience?
P.S. "M/s" means "Megabytes per a second" - it's not a bitrate, it's a real file transfer speed.
