Will this work with links router?

I assume you meant Linksys. Yes, the RE315 should work as an Extender with any common router including Linksys. However, the RE315 OneMesh functionality is designed to work with certain tp-link OneMesh routers. The tp-link web page has a list of their Routers and Extenders that work together to have the OneMesh capability.

Can I plug this into an extension cord?

Yes that is exactly what I have done. I have an outside camera and the download speed was not very good. So I hooked one of these up to an extension and moved it close to an outside wall that has a router on the other side. In addition I put it in one of the little green electrical boxes to keep it covered. I went from 1 meg down load to 6-7 meg download by doing that. The signal needs to go thru the little green plastic box and a vinyl & wood wall to reach the router. I still get 6-7 meg download speed.

Can I connect an Ethernet cable to "feed" the device and not just use it as a wifi extender? i.e, Router cable to this device and then use it as wifi

Absolutely, the ethernet port can be used to create a wired 'Access Point' from your router, thereby providing a Wi-Fi signal in another part of your home where a Wi-Fi signal may have been weak or non-existent. This is the ideal way to use this device if you have the option, i.e., if you have an ethernet feed in a convenient location. Unfortunately that's usually not the case so most people connect the extender to their router via Wi-Fi which will weaken the signal but will often provide a usable Wi-Fi signal where you didn't previously have one. When not in 'Access Point' mode the extender's ethernet port can provide a wired connection for a device like a smart TV, for example.

Does this work with the arris surfboard modem?

Although I don't have specific info about your modem, assuming it has wi-fi and you know the access point name and password, you can easily install the app on your phone and set up the extender to have the same name and password for seem-less connections. Recall that, at best, because of the way this extender works it's maximum speed will be half that of the native wi-fi. But it should significantly increase boost the signal and speed in most cases.

Good Wi-Fi Extender, Easy to Set Up

Very good extender and easy to install. Setup was not plug and play and needed work around for 15 mins in the app which can be simplified. It helped me get strong Wi-Fi coverage in every corner of my apartment. The device supports both 2.4 GHz and 5 GHz bands, extending my main router’s signal with consistently good speed. Satisfied with the performance!

I’ve been really impressed with this TP-Link product so far. Setup was quick and straightforward, and the instructions were easy to follow. The connection has been stable and reliable, with noticeably better speed and coverage compared to what I was using before.

Very happy with my purchase. What i like about this wifi extender is that you can change the passwords within the Tether app, something you cant do with the cheaper models. Would buy again if required

We have a large shop that is a metal building, very poor reception for data 1 bar at best right in front of the doors and 2 bars of wifi from the house but only in the front of the garage. This was a recommendation on several websites and it definitely delivers and at 35.99 is very reasonable. We now have great wifi in the garage and can therefore make and receive calls as well as texts while in the garage. Set up was easy and it worked flawlessly the 1st time
