My ISP provides a 50M(bps) download line for me. But my both laptops only have 802.11g Wi-Fi network card, so my Asus RT-N12 router (firmware upgraded to DD-WRT) has been configured to 802.11g AP with max download 20M. I am not happy with this since the other 30MB is not being used.
I was wondering if I set up 2 SSID on Asus router, and have both SSID uses its own 20M bandwidth? That way I can utilize 40M. Is this possible?
EDIT: It's my router with almost default settings. These are some facts:
- testing speed from several sites, and all got similar results.
- wire connection has 50M download speed, where wireless connection has 20M
- wireless security mode is "WPA2 personal mixed". (not sure if this effects the throughput)
- no QoS
- wireless channel bandwidth = 20MHz (default, unchanged)
- MTU = manual 1492 (default, unchanged)
One of the laptop is Lenovo T420. My NIC is showing "1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter" in device manager. In the property > advance tab, these are properties I saw:
- 802.11d = disable
- Beacon Interval = 100
- Preamble Mode = Short & long
- Roaming Sensitivity Level = Low
- TX Power Level = Auto
- Wiress Mode = IEEE 802.11b/g/n
When setting my AP to 802.11n only mode, my T420 wouldn't connect to the AP. It only connects when AP is set to 802.11g/n mixed mode or below that mode. How could I get 802.11n mode working? Am I having wrong driver?
