Computer connected 23,262,326 23,092,309 under two ports connected a network cable docking looked worktop connection port 2309 and LS-S2326TP-EI-AC    more than 50% , regardless of the opening did not open loopback-detect all the same, to open the 2326 stp useless , 2326 and 2309 are open stp useful exchange 2309 not too stupid machine
