Posted: Sat Jun 06, 2015 1:58 Post subject: n13U B1 : Internet transmission capped at 10Mbps
WAN to LAN and WAN to Wireless (N). In both scenarios my internet speed is capped at 10Mbps. ISP line is 20mbps and is coming fine when directly connected to modem.
Settings I am using
Step 1 ::
Firmware
- DD-WRT v24-sp2 (04/18/14) std - build 23919
- DD-WRT v24-sp2 (12/22/14) std - build 25697
Physical Interfact RA0 - Primary
Mode - AP
Network - N only
Transmission Mode - Mixed
Channel - Auto
Channel Width - 40 Mhz
Extension Channel - Upper
Security - WPA2 Personal - AES
For this particular router, which is similar to my DIR-615 D2, I would go with build 27119, which doesn't have the WebGUI timeout bug (present in builds 27147 & 27240, you can read more in the changelog in my signature). Build 27119 is here: ftp://ftp.dd-wrt.com/betas/2015/05-30-2015-r27119/asus-rtn13ub1/
Use file Asus-RTN13UB1-webflash.bin to go from ddwrt-to-ddwrt.
Then, set the following on the Physical Interface ra0:
NG-Mixed
Channel: 6
Extension channel: Lower
WPA2/AES is OK for security.
What is strange is that WAN-LAN is capped at 12mbps.
Do you have an idea where should I set speed and duplex setting for eth ports
You don't have to. It should work out of the box.
I would reset to factory defaults and re-configure the router manually from scratch. But since I don't know your particular configuration, I can't really help at this stage. Maybe you can post some snapshots of the Setup, Wireless, Wireless Advanced, etc pages, for me to see. Maybe you have a misconfiguration somewhere... _________________ THERE ARE NO STRANGERS HERE; ONLY FRIENDS YOU HAVEN'T YET MET.

OK. First of all, the only config issues I see are on the Wireless -> Advanced page. Change to:
CTS Protection Mode: Disable
TX Power: 71 mW (Don't set more than this, the WiFi signal will be distorted and you also might burn the radio above 100 mW)
Second of all, the PPTP connection might be buggy. If you check the Changelog in my signature, you'll see that PPTP was modified several times in builds: 27086, 26839, 26587, 26490.
To make sure that PPTP is not the cause of the slowdown, I would try the following builds, one-by-one, to check if the PPTP changes modified anything (regression):
26947
26653
26490
26446
Please test each of these builds thoroughly with speedtest.net over WAN-to-LAN and WAN-to-WiFi. Good luck, and please report back with your findings ! _________________ THERE ARE NO STRANGERS HERE; ONLY FRIENDS YOU HAVEN'T YET MET.

If you've obtained these values in speedtest, with the following settings:
CTS Protection Mode: Disable
TX Power: 71 mW
then, honestly, I've run out of ideas. Something's not right there.
Can you test by connecting the router with Automatic DHCP connection to another router (not with PPTP) ? _________________ THERE ARE NO STRANGERS HERE; ONLY FRIENDS YOU HAVEN'T YET MET.

Yes I have run using
CTS Protection Mode: Disable
TX Power: 71 mW
These values are WAN to LAN. WAN to Wireless are marginally less.
I don't know if the following information can be of any help.
-> I have tried file transfer on wireless at N mode. File transfer speeds were achieved at 2.8 MBps
-> My ISP demoed with DLINK DIR 600M. It was giving WAN-LAN 28Mbps and Wireless at 24Mbps. I will try to procure another router and try.
