CHanging TX power/OC and bufferbloat

[John DeLuca]

Hello I was wondering if there was a way to increase the TX strength of a rt-ac5300? If I OC it is there any estimates for what I should set it too? Lastly is there any settings or scrips I can run to decrease buffer bloat because I have a lot of bloat lol.

two questions....

1) increasing tx power - nope - locked down - in any event, doesn't help much.

2) define bloat - it's a bit overdone, but the QoS settings can help out here - tweak and test as general guidance here depends on many inputs...

You can no longer overclock on the latest release routers....ASUS has locked that down as well. If you try, the router will be crippled by going to a severely underclocked state.

The asus routers dont seem to suffer from buffer bloat
but your link to your isp may add jitter

I use no qos at all infact its not even compiled into the firmware

 

[John DeLuca]

Yeah I tried to overclock the router the other day using a script and found it to be even slower then before. So even if I were to add high gain antennas and were able to increase the tx strength (like with Dd-wrt) I wouldn't see much increase in range or decrease in ping

Did you try it with the service-stop approach as outlined here?

I strongly suggest to stay away from antenna change - typically it does not bring much, but it can make things worse - was discussed many times in the forum!

I have an rt-ac3100. It must be a counterfeit unit.
I get a D.

And it has also been documented, with repeated measurements, that if one understands the characteristics of gain antennas the range (and the throughput in previously-weak signal areas) can both be improved.

Antennas cannot "create" power. They just redirect it in defined directions, like a spotlight. And yes, the improvement applies to both the transmitted and received signals.

yeah its odd i have qos set up to adaptive but im still getting crazy buffer bloat.

 

[John DeLuca]

I reflashed the router after trying out dd-wtr and seeing trash preformance on it. This is the bufferbloat i was talking about. Could i run SQM some how on merlin?
This is on powerline

this is on 5ghz

anyone have any ideas qos didn't seem to help much

I must have 2 dud units.
I get terrible BB on the AC88U and AC66U.
If i qos / bandwidth limit i get all A's.

 

[KevTech]

Bufferbloat might be related to what modem you use as well.

Testing three different modems without any change on the router I had these results on every test.

Qos or bandwidth limiting turned off on the router.

Zoom 5370 gets C.

Netgear CM600 gets B.

Arris SB6190 gets A.

Not sure if this is because of bonding more channels or what.

On the 5370 I bond 16/4

On the CM600 and SB6190 I bond 24/4.

how low did you set the limits? i have 110meg down by 6 meg up i set my qos limits to 105 x 5.

you may have to lower your limits. if you had 20meg down by 2 meg up i would start at 18meg down limit and 1.8 limit on the upload

Another thing to bear in mind is that ISP's tend to quote their speeds in multiples of 1000's of bits per second, whereas the QoS values are based on multiples of 1024. So, as always, verify your actual speeds beforehand using something like www.speedtest.net.

For example, if an ISP were to quote a line speed of 110Mbps they mean 110,000,000bps. Which is 104.9Mbps based on 1024.

yeah sorry i didnt mention i calculated my speed from speedtest.net.
