talormanda Posted July 19, 2015 Share Posted July 19, 2015 My old adapter is the AWUS036H http://www.alfa.com.tw/products_show.php?pc=34&ps=92 I just bought a AWUS036NEH from the hakshop http://www.alfa.com.tw/products_show.php?pc=34&ps=22 The issue is that the newer adapter performs poorer than the old one. I would have thought it would be better? The below picture is when I switch adapters, you can see the RSSI gets worse. Quote Link to comment Share on other sites More sharing options...
i8igmac Posted July 19, 2015 Share Posted July 19, 2015 (edited) Its a strange thing... all the alfa cards show different results... you will see more access points with the NEH but The classic 36h always shows better signal stregth... you have to look more into the connection... packet loss, noise, reliability, disconnects... You may notice lower signal stregth but using wireless N faster speeds... Edited July 19, 2015 by i8igmac Quote Link to comment Share on other sites More sharing options...
talormanda Posted July 20, 2015 Author Share Posted July 20, 2015 I got it connected to my network at it only showed 72Mbps. I thought it was 150? Quote Link to comment Share on other sites More sharing options...
i8igmac Posted July 20, 2015 Share Posted July 20, 2015 It depends on the conditions... also if the access point support it... Quote Link to comment Share on other sites More sharing options...
talormanda Posted July 20, 2015 Author Share Posted July 20, 2015 Well. My AP supports 300Mbps so I would have at least expected 150. I connected another adapter to the same laptop and got 144. Quote Link to comment Share on other sites More sharing options...
i8igmac Posted July 20, 2015 Share Posted July 20, 2015 You can try setting the rate... I forget exactly. Iwconfig wlan0 -rate 150M fixed Lol my brain is not recalling the proper data... Quote Link to comment Share on other sites More sharing options...
digip Posted July 20, 2015 Share Posted July 20, 2015 (edited) It depends on the connection channel, signal, power, etc. Rated wifi routers need to be configured for optimal use. I have two 802.11AC routers, which I get 175mbps bridged between them at the moment, but 200+ when I move them closer together. I have a LOT of dropped packets though since they are at opposite ends of the house, but take into consideration all that I have in between the two, this is way better than expected. Before hand, i was usign 802.11 BGN with 2.5ghz 2.4ghz only and I was getting like 1-5mbps throughput with the same amount if not more packet loss(different gateway router and brand than now though). Brand also makes a difference. I have a Netgear a6200 which gets really great speeds, but poor signal and it doesn't let you change an antenna like a lot of the alphas and realtek cards do. If I could, I would probably get way better speeds and signal though. Wifi is subject to a lot of variance, and even same brand cards can vary among revision updates, or models that add more functionality(ie 802.11 N vs 802.11AC) but they may also change for stability in newer models their transmit power and rate with purposely lower speed settings for stability.

cooper Posted July 20, 2015 Share Posted July 20, 2015 The two cards use completely different chipsets (Realtek 8187L vs RT3070. See the specifications page for each) so some difference is to be expected. Quote Link to comment Share on other sites More sharing options...
