RT-N66U: Signal Drop Issue

[shobhitk]

Hi everyone,
i am new here and i am very excited to find this hot and happening community on networking!

after reading many reviews of this router (many of them on SNB) i finally purchased it. i am using it and i must say that i am impressed! signal strength and connection stability are awesome! even the previously dead zones are now receiving 180 mbps connection on 40mhz band!

now today i encountered an issue with the signal strength which is described as under:

i have been using it for last 3 days and the signal strength in the 3rd room from router was constantly above 216mbps, mostly between 216-243mbps; sometimes it even hit full 300 mbps! (on 2.4ghz freq, 40mhz band)

the router was set to default value of 80mW on transmit power. i didnt want more but just for the sake of experiment i raised it to 150mW for just 2 mins. as i did not find any perceivable difference i switched it back to 80mW default setting. now from here onwards my signal strength took a SERIOUS hit. now my laptop was only receiving 54-80mbps !!

not a single thing was changed except the transmit power which was reverted back within 2 mins. thats it! nothing else changed, not even environmentally. but my wifi connection now showed only 54mbp!

i was confused so finally i pushed the reset button and bang....i was again receiving 216-243mbps of rock solid wireless connection.

so guys am still unable to understand this bizarre behaviour. can someone please throw some light....i am sure 150mW for 2 mins. was not too much.

Thanks

How long time did you wait to se if that returned back to you expected speed?

Most people think it's a catastrof when theirs wifi don't show full speed. (300mbps). The importent here is what speed you get when you send files RX/TX. Normal behave is to show with no transfer ~300mbps and when transfer that decrease to a much smaller value and that is how it works.

almost for 2-3 hours. i know octopus that 300mbps is only theoretical but atleast i would get 150mbps of actual throughput. something did go wrong...because otherwise why would it show 216mbps initially and then come down to 54 mbps??
at 54mbps i would only get 27mbps of actual throughput...

10 mbps = 1.25 MBps and that is the speed on a 10/10 LAN.
27 mbps = 3.375 MBps that is god throughput on a wifi connection.
150 mbps = 18,75 MBps.

I think you can't expect more than that.

The numbers you are citing are link rates, not "signal strength".

Since the problem was solved by a router reset (or maybe could have been solved via a simple reboot), you most likely hit a bug.

@octopus i am not saying that 54mbps is a bad speed but the point here is that in the first place why did it fall from 216 to 54 mbps? because if i have to get 54mbps on n66u then for that matter my ISP's b/g modem was also doing a solid 54mbps!....so thats the main issue.
was just trying to understand whether it is safe to fiddle at all with the mW setting.

@thiggins yup my bad...well lets hope that it was a temporary bug.
