Buffalo WZR-HP-G450H Post 20025 Firmware Solution

[n9yty]

I just wish that the dd-wrt community builds could bring up the power levels to the Buffalo versions.  I had to revert to the Buffalo version just because the community builds could not cover the area sufficiently.  The community builds are so much better in every other regard, though. I saw some posts on dd-wrt forums about this, but no responses. {sigh}

@n9yty

Power Levels ARE in the DD-WRT and Buffalo Builds... Have a look at mine on G450H...

They are located Under Wireless->Advanced Settings (Tick Box)-->Tx Power and Antennae Gain

Remember you SHOULD NOT put the antennae gain higher than 5dB as they are only calibrated for that in hardware terms, any higher, you are not using the router as intended and lifespan is shortened as well as an increased risk of overheating (My G125 has a permanent Brown Plastic Burn for example due to a high gain test that went a little wrong)

Hi, I just change my G450H from Friendly firmware to DD WRT - v24-sp2 (04/18/14) std - build 23919 and my Ping Test is now stable. However, there is a new problem.

Here my setting:

Wireless Mode: AP
Wireless Network Mode: NG Mixed
Channel Width: Full 20 MHZ
Wireless Channel : 6 (can't change)
Wireless Network Name (SSID) : mywifi
Wireless SSID Broadcast: Enable
Advanced Settings:
TX P = 20 dBm
RX P = 5 dBm
ACT Timing = 300.


I can't not change the Channel, if i change my channel to another one, my RX rate will drop to 19M, so i just can choose 6 however, sometime, it still drop down but better than changing to another channel.

My computer cannot connect when i change Wireless Channel to 40MHZ. Just connect when i set it 20. However, my phone still connect >"<!

Plz help me, or just suggest some other version of firmware.

Thanks and Regards

The Turbo/40MHz setting is only supported on some devices, not all, the reason your phone works and not your PC is most likely down to the PC's wireless adapter not supporting the 40Mhz channel width... Changing the routers firmware will not change your devices ability to connect to a 40MHz channel... Changing your wireless devices firmware MIGHT allow you to connect to the router if the manufacturer has released such an update...

I will need a bit more information on exactly how you are testing your Rx rate and what devices you are using to see if the drop is firmware related (I doubt it though; many factors affect throughput, firmware problems are some of the least likely causes particularly when talking about wireless connections)...

JacobD84, I updated the router with build 23919 version. And I noticed that the range of wirelles was getting weaker or achieve in every room of my house, with original build before reached in the whole house. Below is a config prints and where the router is located. Thanks for listening, I await your help.

I can not go back to the original firmware, where do the installation, it is still in build 23919. Any help please?

[bohdee]

JacobD84, are you there?

So has anyone tried the latest r24461?

[JaniN83]

23919 does seem to have a definite range problem.  On the other hand, there is a great improvement in wireless speed. 

I used to be able to go over 100 yds from my house with r23838.  (I live in a rural area.)

My antenna gain might have been reduced to 0 after this upgrade.  Note I never reset during a flash.  The moderators of DD-WRT almost always advise against it.  Changing antenna gain to 5 db has increased the range.  I wish remembered what the setting was before the upgrade.

So is it best to use these settings?

TX Power 20 dBm
Antenna Gain 5 dBi
TX Antenna Chains 1+2+3
RX Antenna Chains 1+2+3

Does r23919 have the NTFS support?

Check on the DDWRT website. There are wikis for this.
