Hi,
I was testing out rt-n56u against a wn612v2 on 2.4ghz performance.
Testing setup: main router 2.4ghz.
Both rtn56u and wnr612v2 at the same spot with only one turned on during testing. They are about 20feet away across two walls from main router. Both are set to station mode (wireless client).
I ran iw wlan0 station dump and notice the following:
rt-n56u:
rx bytes: 37833551
rx packets: 30475
tx bytes: 18052194
tx packets: 23966
tx retries: 13536
tx failed: 799
beacon loss: 0
beacon rx: 298
rx drop misc: 5
signal: -53 dBm
signal avg: -53 dBm
beacon signal avg: 213 dBm
tx bitrate: 144.4 MBit/s MCS 15 short GI
rx bitrate: 78.0 MBit/s MCS 12
expected throughput: 40.191Mbps
wnrt612v2:
rx bytes: 66909517
rx packets: 54627
tx bytes: 11039868
tx packets: 28325
tx retries: 3597
tx failed: 0
beacon loss: 0
beacon rx: 3334
rx drop misc: 8
signal: -49 [-49] dBm
signal avg: -53 [-53] dBm
beacon signal avg: 205 dBm
tx bitrate: 58.5 MBit/s MCS 6
rx bitrate: 58.5 MBit/s MCS 6
expected throughput: 35.705Mbps
rt-n56u has substantially higher retry rate (56.5% vs 12.7%) and tx failure rate (3.33% vs 0%). When I was using rt-n56u as the main router I noticed much slower throughput and random latency spike on the 2.4ghz channel and thats why I decided to test the tx in station mode.
Questions
Is this simply a hardware difference or does it indicate that I have a faulty 2.4ghz chip for tx?
Am I looking at the right place to figure out the performance issue?
ifconfig packets statistics:
RX packets:48634 errors:0 dropped:0 overruns:0 frame:0
TX packets:28854 errors:0 dropped:0 overruns:0 carrier:0
