Hi, man iwconfig tells, "Link quality... depends totally on the driver and hardware". I would like to know how to interpret the value for WPEA-127N driven by ath9k - ideally to have a base value for estimation of "useable bandwidth" (i.e. how much data could be sent and received per time).
Is this feasible? Is parsing the output of "iwconfig" in intervals a good approach? Which polling interval would be suited? What would be a better way / correct way? I tried "wpa_cli -p $path signal_poll", but it returns only "FAIL" (however, commands work). Do I something wrong? It would be good to estimate the order of magnitude (if there are 2 or 20 MBits) and having a value to compare several links. Surely this is a very complex topic (Google found heaps of papers about), but I'm looking for a starting point for a rough "guess", but hopefully still a bit reasonable. Any pointers appreciated!
