wolfdale Posted November 16, 2013 Share Posted November 16, 2013 I was using reaver today for about an hour and the pineapple had a burn smell to it. I measured temperatures (with the case off) with my IR thermometer and the heat seems to come from the RTL8187 chipset (about 50 degrees celsius) and I couldn't keep my finger on it for more than 2 seconds... I then measured idle temps (i gave ifconfig wlan1 down command) and it was 40 degrees. Measurements were taken with the case off so the temperatures would get higher with the case. Whats the operational temperature of the chip? Should i be concerned ( plastic burn smell..) about the temperatures? Thanks in advance.

Mr-Protocol Posted November 16, 2013 Share Posted November 16, 2013 I wouldn't think reaver would cause the chip to heat that much. Have you messed with the TX power at all? Quote Link to comment Share on other sites More sharing options...
C3PBRO Posted November 16, 2013 Share Posted November 16, 2013 Could somebody tell me how the case off? Im curious about my temps aswell... Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted November 16, 2013 Share Posted November 16, 2013 Could somebody tell me how the case off? Im curious about my temps aswell... Same as most other things, removed the rubber feet on the bottom, there should be some screws. Quote Link to comment Share on other sites More sharing options...
wolfdale Posted November 16, 2013 Author Share Posted November 16, 2013 (edited) Didn't touch the txpower. I'll check right now how high it is set by default. Edit: ouch 27 dbm. I tried lowering it but iwconfig wlan1 txpower 20 isn't working :/ Edited November 16, 2013 by wolfdale Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted November 16, 2013 Share Posted November 16, 2013 That might be why it's getting hot. And odd odors are either a red flag/warning or a bad sign. I don't mess with TX Power so I'm not sure how you can lower it if that command didn't work. Quote Link to comment Share on other sites More sharing options...
thesugarat Posted November 16, 2013 Share Posted November 16, 2013 (edited) Try iwconfig wlan1 txpower 20dBm Comes from this thread: https://forums.hak5.org/index.php?/topic/30748-txpower-woes/?p=231588 Edited November 16, 2013 by thesugarat Quote Link to comment Share on other sites More sharing options...
wolfdale Posted November 16, 2013 Author Share Posted November 16, 2013 It shipped with txpower set at 27 dbm. I never messed with it :P My alfa with RTL8187L does get warm also, so maybe its just a hot chip. Try iwconfig wlan1 txpower 20dBm Not working :/ Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted November 16, 2013 Share Posted November 16, 2013 It should be unlocked and able to modify. Quote Link to comment Share on other sites More sharing options...
thesugarat Posted November 16, 2013 Share Posted November 16, 2013 I agree they get hot.... But did you try to bring it down first before changing it? ifconfig wlan1 down Then set power then ifconfig wlan1 up Quote Link to comment Share on other sites More sharing options...
wolfdale Posted November 16, 2013 Author Share Posted November 16, 2013 Yep, still nothing. Quote Link to comment Share on other sites More sharing options...
thesugarat Posted November 16, 2013 Share Posted November 16, 2013 Try 18dBm or other numbers.... It might be an issue with trying to set it to 20. Quote Link to comment Share on other sites More sharing options...
wolfdale Posted November 16, 2013 Author Share Posted November 16, 2013 (edited) Got it working. ifconfig wlan1 down iw reg set IT ifconfig wlan1 up Since Italy allows only 20 dbm transmit power, when the interface comes back up its at 20 dbm. I'll test temps now. Edit: temps are 5 degrees cooler (45) but wash doesn't seem to work correctly with the new regulatory domain.. airodump works fine though. Maybe Seb or Darren want to hop in and tell us what they think about these temps :) Edited November 16, 2013 by wolfdale Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted November 16, 2013 Share Posted November 16, 2013 Hmm you may have to down the interface before changing TX Power. Did you try that? Edit: Nevermind, I just read previous posts. Quote Link to comment Share on other sites More sharing options...
Z4ub4d3 Posted November 16, 2013 Share Posted November 16, 2013 Silly question, but are the antennas connected properly? Quote Link to comment Share on other sites More sharing options...

chriswhat Posted November 17, 2013 Share Posted November 17, 2013 (edited) wolfdale, This is how I do it: 1) Connect to your Pineapple via ethernet cable or WiFi 2) SSH into your Pineapple - "ssh root@172.16.42.1" 3) Put wlan1 down - "ifconfig wlan1 down" 4) Set the region to United States - "iw reg set US" 5) Confirm that the region was changed - "iw reg get" Note: You should see "Country US:" 6) Set wlan1's TX-Power to 20dBm or whatever power level you want - "iwconfig wlan1 txpower 20dBm" 7) Put wlan1 up - "ifconfig wlan1 up" 8) Now confirm the TX-Power change - "iwconfig wlan1" Edited November 17, 2013 by chriswhat Quote Link to comment Share on other sites More sharing options...
wolfdale Posted November 17, 2013 Author Share Posted November 17, 2013 (edited) I followed your steps but "iwconfig wlan1 txpower 20dBm" doesn't do anything (txpower stays at 27). It works on your pineapple? Edited November 17, 2013 by wolfdale Quote Link to comment Share on other sites More sharing options...
thesugarat Posted November 17, 2013 Share Posted November 17, 2013 Question are you using iwconfig wlan1 txpower 20 or iwconfig wlan1 txpower 20dBm the dBm part is important... Quote Link to comment Share on other sites More sharing options...
chriswhat Posted November 17, 2013 Share Posted November 17, 2013 Yes, those are the exact steps that I take on my Mk V, and I never have any issues. Not sure why you're having a problem. Make sure wlan1 isn't associated with any access points. ifconfig wlan1 down dhclient -r wlan1 Then complete the steps I gave you above.

Sebkinne Posted November 17, 2013 Share Posted November 17, 2013 Yes, the rtl does get very hot. But it's rated fine for even higher temperatures, so nothing to worry about. Quote Link to comment Share on other sites More sharing options...
wolfdale Posted November 17, 2013 Author Share Posted November 17, 2013 (edited) Question are you using iwconfig wlan1 txpower 20 or iwconfig wlan1 txpower 20dBm the dBm part is important... Yeah i specified dBm. I used to do these same steps on my alfa Yes, those are the exact steps that I take on my Mk V, and I never have any issues. Not sure why you're having a problem. Make sure wlan1 isn't associated with any access points. ifconfig wlan1 down dhclient -r wlan1 Then complete the steps I gave you above. I get can't find dhclient. I even did a reset of the pineapple today, and still nothing. I'm on firmware version 1.0.1, maybe thats the cause? Yes, the rtl does get very hot. But it's rated fine for even higher temperatures, so nothing to worry about. Thanks thats a bit reassuring :) Edited November 17, 2013 by wolfdale Quote Link to comment Share on other sites More sharing options...
Boosted240 Posted November 18, 2013 Share Posted November 18, 2013 I did nano /etc/config/wireless And added the line option txpower '20' To wlan0. I also added the line to wlan1 and wlan2 for '22'. wlan1 is the only one that will change. wlan0 and wlan2 (my Alfa) both remained 18 and 27dBm. I haven't had much luck at all getting tX power to change with the pineapple. I've also tried the process of taking a radio down, changing txpower (with dBm) radio up, and no luck. I tried lots of different numbers. (before I made the changes to the config) Quote Link to comment Share on other sites More sharing options...
wolfdale Posted January 26, 2014 Author Share Posted January 26, 2014 Little update on the topic. I know it's probably not neeed but I added a little RAM heatsink on the chip, and now it's not even warm to the touch! Now it looks really cool :D http://it.tinypic.com/r/dcgbyo/5 Quote Link to comment Share on other sites More sharing options...

Now it looks really cool :D http://it.tinypic.com/r/dcgbyo/5 Very "cool" wolfdale........pun intended. Great mod.........Thanks.... I need to go find a few heatsinks, no need to up my tx power, but one would think being cooler would extend the life of the product. Quote Link to comment Share on other sites More sharing options...
