I have Frontier as an ISP. I say throttleing because sometimes my download/upload which is supposed to be 3616 Kbps / 896 Kbps , will be like less then 500kbps/ 100kbps. Also i get frequent disconnects which i think are from packet loss. My wifi extender is set up optimally so while i know it isn't as ideal as directly hooked up to the router via ethernet it doubt it would cause bandwith throttling/packet loss to that degree.
Frequent disconnects from wifi or from internet, two very very different things here.
So I am assuming you have DSL then at those speeds. DSL is more severely impacted by network congestion of your neighbors/other frontier customers, as well as more greatly affected by how far you are from your network hub (you use copper from your house to that node hub, while that node hub to the main office should be fiber optic cable at this point).
WiFi extenders are single radio devices that play middle man. So lets say you have an older 54mbps wireless G wifi setup. So once you account for real world speed performance, signal loss from distance/obstacles, and other factors you are probably really only getting around 15 mbps real speed received by the WiFi extender. Except the extender is a middle man with only 1 radio so it has to split that 15mbps in half because it has to talk to yoru computer, stop, talk to the router, stop, so on and so on. So that 15 gets split in half and with a little loss you end up getting about 5 mbps at yoru device.
Not to mention most people install them incorrectly and instead of installing them at the halfway point where the signal is still good, they install them right near the desitnation point where the signal already sucks. If the repeater is only getting 1-2 bars that is going to output next to nothing for wifi speeds, and there will be a tremendous delay doing it.
If your getting discconects from the internet itself then you need to be calling Frontier to get them to inspect the connection to the house and that the connection to the modem is solid.
Are you using the filter's that should have came with your modem? If not your phone system can be causing very noticeable interference with your dsl modem and be causing the problems you are having.
