If you set the Extension Channel to "lower" does something change? I might suggest also posting this to the big monster thread.
Selecting channel 149 only provides "upper" as the extension choice. Selecting 157 provides no choice, extension is blank/empty. Selecting 165 provides "lower". Likewise, channels 136, 140, 144 are all empty extensions.
BTW - selecting and applying a channel with an empty extension causes instability - 5GHz doesn't show, router slows and other issues.
That kind of confirms what I'm thinking. It seems DD-WRT is reserving an entire 80Mhz block so only 149/upper and 165/lower are useable. _________________ Routing:.......Asus RT-AX88U (Asuswrt-Merlin 384.14) Switching:....Netgear GS608_V3 & GS605_V4, TrendNet TEG-S82G & TEG-S50G
Not all channels are available in all Regulatory Domains.
This is also true, although I'm not sure that's the exact issue here. _________________ Routing:.......Asus RT-AX88U (Asuswrt-Merlin 384.14) Switching:....Netgear GS608_V3 & GS605_V4, TrendNet TEG-S82G & TEG-S50G
I was having some great speed and range using the original 167514 firmware from Linksys but decided on trying DD-WRT on my V.1. I love the interface and everything I can do, but I'm not really getting a good and stable connection on my 5Ghz band. 2.4 is disconnected. Nothing I have uses it. Would someone please be able to give me some pointers as to which settings to change? Also, I'm using the official release for the router "DD-WRT v3.0-r28628 std (12/29/15)". Any help or pointers would really be appreciated.
I have a WRT1200AC, but I think it's basically the same hardware as the WRT1900. I have been using my router for quite some time, with very poor transfer speeds. I just thought it was because I had setup openVPN on the router and that was causing the issue. But I didn't understand why it would affect the local traffic.
Anyway, I came across this post while I was searching how to get better speeds. I noticed the issue when I was checking out the Mac's tool "network utility". It will display the link speed when connected to wireless networks. I noticed on my ISP provided router, I was getting 450Mbps and 217Mbps on the 5ghz and 2.4ghz.
On my WRT1200AC running DD_WRT, I was only get 144Mbps on both the 5ghz and 2.4ghz network.
I noticed my 5Ghz network channel width had been set to Full 20Mhz. So I tried changing it to Dynamic 20/40Mhz and then checked the network utility again and I was now getting 300Mbps. WOW!
My transfer speeds are such an improvement now. However, now that I have had a taste, I'm wondering if I can get the link speed to get up to where it should (i.e. 450Mbps).
Anyone know what settings I should set to get this working at this level?
I have tried that, but the result is not good. If I set to channel width of 80, the link speed drops to 144. If I put it back to Wide HT40, channel 48, extension: lower. It will go back to having a link speed of 300. I can't seem to get any better than 300.
Any ideas why? Is this an issue with the dd-wrt firmware for my router?
Anyone else have a WRT1200AC and able to achieve 450 link speed?
