thanks for replying! Could you help me understand the difference between those two routers? Also the wireless adapters i installed in the desktops are only 2.4ghz is the 5ghz a major difference? What would you recommend for the repeater should i use the same brand to ensure compatability?
The difference has to do with age, price, and features for the most part.
5Ghz is less congested, as a result it won't receive interference from your cordless phones (unless you have the DECT 6.0 phones) or the microwave. The speeds aren't really that different. Most of the devices work well with other brands, but you could keep the same brand if you want. The options the poster above listed are decent low-cost options, but I don't know a thing about TP-Link. I'm not super familiar with the consumer wireless repeaters, as I work with and own enterprise gear.
