Why are my VeseNet HomePlugs not working well? The second PC Internet connection is very slow. Why?

Question

I use BT Broadband through a BT Voyager 2000 Wireless ADSL Modem. From this I run an ethernet cable into a NetGear 5 port Ethernet switch. From the switch I run an ethernet cable into the PC next to it (this PC!). No problems. To connect the kids PC (in another room) I was recommended two HomePlugs. From the 5 port NetGear switch I run an ethernet cable into what looks like a battery charger. It plugs into the mains. In the other room where the 2nd PC is there's another of these battery charger things plugged into the mains. From this runs an ethernet cable into the 2nd PC. The internet speeds are very slow. Any suggestions?
It used to run ok before (same set up) using different HomePlugs (I think the brand was HomeLink). These broke (blew up) and were replaced by the supplier.
I can't use the wireless part of the modem because the 2nd PC/room is too far away. Would a new router (more powerful?) be better? - I could go wireless again which I would prefer.

Answer 1

Well - the HomePlug standard is not really much of standard. Althought the 1.1 revision suggests a speed of 14mbit, I seldom see that speed. Different brands of HomePlug devices have wildly differing speeds. The reason is that the device takes an ethernet packet, then wraps it into a "homeplug" packet which is then sent via radio frequency using the ground wire of the electric system. So, it's like if you went to Walmart and purchased 10 FM radios. Then took each one into your basement and turned it to a far away station. Every radio would likely deliver a differing quality of sound. Each HomePlug "tranceiver" (battery-pack looking-thing) broadcasts using a tiny amount of power. The other tranceivers listen and tell them to slow down if they have poor reception. So - either get an ethernet cable to the kids room, or switch to wireless and use a wireless repeater if necessary, or go to a store that has a refund policy and and try a new set from a different manufacturer, or finally contact the manufacturer of the current set and tell them that you are having poor quality.

No you could open much and it won't influence something. What may be the factor of having the DMZ function in a router if beginning ports replaced into undesirable? in case you do no longer understand what DMZ is google it. shopper provider human beings these days desire to purpose to bypass the greenback to somebody else fairly of looking the actual reason as a results of fact looking the reason expenses money, at the same time as telling you it is somebody else's fault is plenty some distance greater low priced.
