Asus RT-N12+ I can't get 300mbps!

[SKREFI]

I have an Asus RT-N12+ and it is supposed to handle 300mbps. Today I made a upgrade from 100mbps to 300mbps. If I plug the cable right in the PC, the 300mbps works but if I use the wireless it stuck at 100mbps.

That router CAN NOT provide 300Mbit on wired or wireless. All the wired ports are 100Mbit -- https://www.asus.com/Networking/RTN12Plus/specifications/ The 300Mbit rating is just marketing for the wireless. The maximum wireless throughput is 150Mbit (1/2 the advertised rate because WIFI is half duplex). BUT the 100mbit wired port limit it below that. You will get 80 - 90 Mbit from that device.

What ? I see it have 300mbps... and on it says: 300mb bla bla bla............... On the box the same... I bought it only for 300mb, already had a 100 wireless.

Welcome to the world of marketing vs engineering. The 300 number only represent a speed in some lab test that does not correspond to any real world installation.

What it really is a short hand representation of a complex list of data encoding, modulation and data streams. If you really want to see it search MCS index. It mostly represents a short hand for how data is placed into the wireless radio signal.

But because of how things really work no wireless can run that fast. The reason the router only has 100m ports is you will never get close to 100m on using a 300m wireless encoding scheme. Even using the most complex one there is for the 2.4g band that uses a number of 600 you still only get about 100m.

Even using the most advance 802.11ac router and very rare 4 antenna network cards for your pc you will have a hard job getting 300m consistently.

You bought the wrong router.

Your LINK RATE -- what Windows says the speed between the router and the PC may show 300Mbit. BUT, the amount of data that can be transferred is 150Mbit. WIFI -- by definition -- is half duplex. That means that a WIFI device can either transmit OR receive but not both at the same time. So 1/2 the time is spent by the router transmitting at 300Mbit and 1/2 the time is spent by the router receiving at 300Mbit -- Consequently the throughput is 150Mbit. That router has 100Mbit wired ports. That is the limiting factor. Nothing can change that.

Wait, so there is no router capable of 300mbps ? -_-
