... btw: there is no problem ... I am just curious ... and inquiring
if someone can explain the following behavior ...
... my DIR-655 wireless-router reports connection " RATE"(s) (i.e. "STATUS - WIRELESS" )
that seem inconsistant with my understanding of the 802.11n, wifi data-rates : -- see tables published eslewhere ---> [ ...search ... 1) wiki : mcs data rates or 2) google : mcsindex ]
The Wireless Configuration for DIR-655 router & DAP-1522 bridge (client) is:
The router reports signal strength from client is 100%, which is v. good.
My confusion arises from the "RATE: i.e. client connection speeds" as reported by the router.
These rate reported most is
241Mbps, but is sometimes
214Mbps, or else it is reported as
... FIRST curiousity ...
The rates reported by the DIR-655 do NOT coincide exactly
with the MCS-index/data-rate tables.
---> [ ? 2 spatial-streams ... ? 64-QAM ? ]
reported:214M is similar to 216Mbps (MCS 13 | 800GI)
reported:241M is similar to 243Mbps (MCS 14 | 800GI) or
reported:241M is similar to 240Mbps (MCS 13 | 400GI)
reported:268M is similar to 270Mbps (MCS 15 | 800GI) or
reported:268M is similar to 270Mbps (MCS 14 | 400GI)
? what could be the reason for this ~2M discrepancy ?
Is the small discrepancy due to wireless/processing header/overhead,
non-data transmission-rate compensation/correction ...
or is it something more sinister ? lol
... SECOND curiousity ...
With BOTH the DIR-655(router) and the DAP-1522(client) configured for "SHORT GI" ( i.e. 400GI) ...
... why would ANY connection-rate associated with the " 800GI " setting be possible? (refer to above-data as reported in "FIRST curiosity" )
