TP-Link Archer C7 Wireless Dual Router AC1750

Does anyone know if this is 100% obsolete? If not how much can I get for this? Thank you Hi, 💕 Am selling everything I own except the bare essentials to fund my egg freezing fundraiser of $30k++ bc my insurance doesn’t cover it & I have a health condition = high risk for never being able to have kids. 💕 My rating 4.8/5 Only used for 1 year I did a lot of research before I purchased this and it’s the best! Don’t have the original box! But have all the cords. The instruction manual can be downloaded on their site. Was $129.99 TP-Link Archer C7 Wireless Dual Band Router AC1750
