Hi there,

Really stupid question - what is the power supply requirements for the Mega 100WR?

someone has taken my router's power supply and now I am stuck! I know it is 9V DC but what AMPS - I don't what to blow it.

Thanks
 
Amps does not work like that.

Amps will be the maximum that the router can draw from the power supply before the power supply cannot cope.

The worst that will happen is that the router does not get enough power and cannot startup.

If it's drawing more than 1 amp then there is something seriously wrong with your router. My ALCATEL ADSL modem says 0.2A on it's base.
 
I just checked my 100WR's power supply, and it's just a solid box with no specifications on it. If it is 9V you could probably get away with any DC 9V transformer with 1000mA and up.. maybe even less
 
I have a Microcom Router, it looks exactly like the Mega 100/105, it just has a differnt colour and the web interface is green whereas the Mega is blue, the PSU is 9V 1000mA
 
I got a spare mega 100 psu that you can have for free if you're in the pta area.
 
A while back I hooked up my Mega100WR to a meter. Running, it drew 0.02A, 4W, 6VA.

Any 9V PSU should do, but don't forgot some kind of surge protector. The one supplied by Telkom claims to include surge protection (has sockets for the phone line as well).
 
Sorry to be bumping an old thread, but just though i'd let you guys know, my Mega 100WR runs on a 12V @ 1000mA, not 9V as previously thought !
=)
 
Hi All,

The Mega 100WR, Mega 100WR2 and the Mega 105WR all use 9V PSU's.
The actual current drawn depends on how you are using the Router ( How many PC's are connected, whether USB, WiFi are been used, connection speed, Data been downloaded etc) what we supply the router with is a PSU capable of 1 A (or 1000mA if you prefer it in mA)

If you are going to use an alternative supply, which in terms of warrentee we do not recommend, you should try to match these values. Using an under rated supply may work, but but could result in unstable operation at times.

While using a 12 V Psu will work, it will result in the router running hotter, wich will result in reduced router lifespan.

I can recomend the use of a surge protecting supply, due to current electricity supply conditions, as will as the upcoming lightning season.

Hope this helps.
 
Interestingly, I had a lightening surge on my phone line while it was plugged into the surge protector on this power supply. The lightening blew the rectifier, two caps and EVERY trace clean off the power supply's PC board. The porcelain surge protector thingy was still intact.

Luckily the phone line was unplugged from the router, but my network cable (which runs through the attic) must have picked up some current and blew the ethernet ports on the router. The router still works through USB though, with some phantom flashes on the E1 led.

Whoah... yeah I find when lightning strikes, the easiest things to go always seem to be network cards, switches, and of course anything connected to the phone line. I've not once lost equipment through powerline, but then again I do have like three snapper surge protectors plugged into each other in series. Whether that makes things better or worse in theory, I dont know, but as I say fortunately I've never had any noticable damage from lightning that came through the power sockets; and yet I've lost MANY phones and modems through the telephone line!

Well it's not like they last anything longer than six months anyways, so what's to lose?

? Mine's lasted over a year now. assuming you dont get hit by lightning, it should last many years

Mine started giving issues after 8 months, I updated the firmware and now the WPA doesn't work. Can't do anything else with it. I HAVE to restart it every 24 hours, otherwise my internet just stops working...
Sure it "lasts" over a year, it just doesn't mean it's working.
