Q&A:1.My verizon DSL service comes through the phone line. My new wifi router has only ethernet input. Will this product work for me?Answer:No, your DSL service needs a DSL modem between the incoming DSL phone line and your router. The modem will provide a phone port and an ethernet port. This product could then be used to plug into the phone port to use ethernet cable to carry the phone signal across your building where it can be converted back to provide a phone jack connection to plug in your phone.2.Would this work to connect my new printer to my internet modem?Answer:Definitely no. The cable is for connecting a DSL modem with an RJ-11 connector to a wall outlet using an RJ-45 connecting to a CAT5 cable to a whole-house DSL filter. If your printer has Ethernet capability, you need a a CAT5 jumper that can easily be found on Amazon or from other sellers. This jumper can connect from RJ-45 router Ethernet connectors on your modem to the printer.4.Will this enable me to connect an Ethernet cable from network extender to a cable modem with only one WAN port and one called "USB", but looks like phAnswer:NO. it will not work with USB.6.Has anyone tried this with ooma office? i'm trying to connect a phone that has female cat5e ports to an ooma linx phone jack.Answer:The Ooma Linx is a device that connects a plain old telephone system (POTS) type phone to the Ooma Telo which is a voice-over-IP (VOIP) device that can be used with its own wireless handset. If your phone is an old multil-ine POTS type phone that used an 8 contact RJ-45 female connector, it is possible the cable will work with line 1 on the multi-line phone. It may also be possible you are trying to connect a VOIP phone to the Ooma Linx -- which will not work.
