 dmesg | grep iwl  [   22.101948] iwlagn: intel(r) wireless wifi link agn driver linux, in-tree:  [   22.101953] iwlagn: copyright(c) 2003-2011 intel corporation  [   22.102025] iwlagn 0000:03:00.0: pci int -> gsi 18 (level, low) -> irq 18  [   22.102035] iwlagn 0000:03:00.0: setting latency timer 64  [   22.102062] iwlagn 0000:03:00.0: detected intel(r) wifi link 5100 agn, rev=0x54  [   22.124221] iwlagn 0000:03:00.0: device eeprom ver=0x11f, calib=0x4  [   22.124224] iwlagn 0000:03:00.0: device sku: 0xb  [   22.127777] iwlagn 0000:03:00.0: tunable channels: 13 802.11bg, 24 802.11a channels  [   22.127915] iwlagn 0000:03:00.0: irq 47 msi/msi-x  [   22.435246] iwlagn 0000:03:00.0: loaded firmware version 8.83.5.1 build 33692  [   22.453312] ieee80211 phy0: selected rate control algorithm 'iwl-agn-rs'  [   65.785062] iwlagn 0000:03:00.0: aggregation not enabled tid 0 because load = 3  [   71.659853] iwlagn 0000:03:00.0: aggregation not enabled tid 0 because load = 7  [   82.666252] iwlagn 0000:03:00.0: aggregation not enabled tid 0 because load = 0  [   88.330188] iwlagn 0000:03:00.0: aggregation not enabled tid 0 because load = 6  [   93.785809] iwlagn 0000:03:00.0: aggregation not enabled tid 0 because load = 2  [   97.752041] iwlagn 0000:03:00.0: iwlagn_tx_agg_start on ra = 00:26:5a:5a:db:78 tid = 0  [  130.841542] iwlagn 0000:03:00.0: aggregation not enabled tid 6 because load = 0  [  314.447807] iwlagn 0000:03:00.0: aggregation not enabled tid 6 because load = 2
i'm getting these "aggregation not enabled" messages, , don't have clue means.

code:
lspci -nnk | grep -ia2 network  03:00.0 network controller [0280]: intel corporation wifi link 5100 [8086:4232]  	subsystem: intel corporation wifi link 5100 agn [8086:1201]  	kernel driver in use: iwlagn
i made research , got install these files:

linux-headers-3.0.0-0300rc2_3.0.0-0300rc2.201106081532_all.deb
linux-headers-3.0.0-0300rc2-generic_3.0.0-0300rc2.201106081532_i386.deb
linux-image-3.0.0-0300rc2-generic_3.0.0-0300rc2.201106081532_i386.deb

i've got problem when installing 1 of them:

setting linux-headers-3.0.0-0300rc2 (3.0.0-0300rc2.201106081532) ...
setting linux-headers-3.0.0-0300rc2-generic (3.0.0-0300rc2.201106081532) ...
examining /etc/kernel/header_postinst.d.

error! not locate dkms.conf file.
file: not exist

the n-mode of driver buggy, deactivate via

code:
echo "options iwlagn 11n_disable=1" | sudo tee /etc/modprobe.d/iwlagn.conf  sudo modprobe -rfv iwlagn  sudo modprobe -v iwlagn

how devide circle equal parts reggie,   depending on version, may able use free divide (length) script available here, setting number,   http://park12.wakwak.com/~shp/lc/et/en_aics_script.html   or may (smart guides friends):   1) use polar grid tool right size of circle, 0 concentric dividers , desired number of radial dividers, , ungroup; 2) extend radial dividers; 3) select circle , use scissors tool @ intersections (smart guides intersect ), may need select remaining parts underway.   or may (smart guides friends):   1) create vertical line through top , bottom (or left , right) anchor points line tool; 2) rotate copies @ relevant angles (to half number of cuts division); 3) select circle , use scissors tool @ intersections (smart guides intersect ), may need select remaining parts underway.
