Has anyone used wifi extenders are they reliable, i want a LAN connection to my pc it did not have wifi module so looking at the wifi extenders with a lan port , this one is looking into this but not sure how much this is reliable any reviews?

I'd prefer buying a regular 5Ghz router and using that as an extender. They usually have better performance and coverage. Almost all brands support extender mode. But for best performance, try to connect both the routers with LAN cable if possible.

Wifi extenders used to wirelessly extend networks drop speeds by 50% and higher as the distance increases. I have personally experienced this and then switched to extending via a physical lan cable and having a proper router at the end which can be placed close to your PC. So wireless repeating is not recommend at all.

Extenders are not reliable. Unless you are plugging in a LAN cable to the extender, you will see massive drop in speeds when you try to hop off from wifi -> wifi. Things may have slightly improved now, but a few years ago, I had gone the extender route. The 8 Mbps wifi connection would drop to 2 Mbps on the extender. So I would not recommend it. If pulling a wire is not possible, try and get one of those mesh routers. I have been using the Deco M4s for a while now and can recommend. They have reasonably priced E4s but limited to 100 Mbps. But even these are not infallible. Things like closed doors, many walls, etc. affect their speeds. But still you can expect decently workable speeds with these compared to using wifi to wifi extenders.

@loud-glass-33663 I have a 75mbps plan & wifi router is currently placed in 1st of a room & the same room in the 2nd floor is what I use for my work needs, My Wifi speed dips to over 10-20Mbps, if I had to measure the distance vertically in height it’s somewhere around 30 ft or so. Do you think getting a mesh router can help solve the problem? What would you suggest between M4s & E4s to me? Getting a LAN connection is kinda tricky & needs some drilling to the infrastructure which I want to avoid at all costs.

@mammoth-kilobyte-43714 In my experience - mesh routers REALLY help with dead zones. And only slightly with speed bumps. I have a deco router right outside my door - but when I kept my door closed (kids) during calls, I noticed drop in video / freeze frames every now and then. If you have an open space, then it should be fine. But If you have walls and doors in between, I don't think you may experience a substantial boost in speeds. I eventually pulled a CAT 6 flat cable through the door to my computer. Pulling a wire is the most headache-free solution. The flat ones are decently concealable and you can close the door and have it pass between the gaps (unless you have a really tight fitting door). If you do decide to go for mesh, get the E4 only if you don't see yourself getting > 100 Mpbs internet connection in the next 2-3 years. The M4 will be more future proof that ways (even though more expensive today). Hope this helps.
