Can I use N150 USB wifi adapter on N300 Router?

[jaye3rd89]

I'm trying to make my desktop internet able via wireless on our Netgear n300 wnr2000v5 router so i was going to buy a USB wifi adapter (preferably this one since Amazon recommended it)

https://www.amazon.com/gp/aw/d/B008IFXQFU/ref=mp_s_a_1_4?ie=UTF8&qid=1515817214&sr=8-4&pi=AC_SX236_SY340_FMwebp_QL65&keywords=Usb+wifi&dpPl=1&dpID=41hApAgDVxL&ref=plSrch

But its N150.

As far as i can tell both support 802.11 b/g/n.

Would I have an issue using this adapter?

Yes, but it's not ideal. Your router's maximum Phy rate is 300 Mbps, and that adapter's Phy rate is 150 Mbps. A good rule of thumb for throughput at zero distance is 40% of the PHY rate, so you might expect 60 Mbps rather than 120 Mbps, and that decreases as the distance and obstructions between the two devices increase. The router's CPU clock and RAM are low, and the adapter is only USB 2.0, so don't expect much.

I'd also like to add that when I went into the router by default the mode it was on was set to "up to 150mbps) I didn't bother increasing it to 300 as I didn't know how that would affect the other wireless devices. (Whenever they are actually used) in the house.

The 54 Mbps mode would be for 802.11g devices, 150 Mbps would be 802.11n SISO (single spatial stream), and 300 Mbps would be 802.11n 2x2 MIMO (two spatial streams). With 300 Mbps, your router tries to use two spatial streams spaced at 40 MHz widths. Whether the 150 or 300 Mbps mode is better depends on the chipset of your other devices, as well as the signal strength where they are.
