Ok so I have this Billion BiPac 7300 router which I used at my old house then I moved and when I set it up again it just wouldnt sync. So after $200 for a ISP tech to come and check my setup and phone cable wiring the ISP gave me a Netcomm NB5 Router to use instead also the ISP had to set a special profile to actually get sync.

 

Anyways last night we decided to move some furniture around and now my desk is about 6-8 feet away from where it was and while cleaning up I decide to try the old Billion router again and presto it seems to work again, syncs with a better D/L speed but lower U/L speed, weird?

 

The location where the router was before is right near 2 flouros and a large mains power section in the roof (possibly dodgy electrician work for the fluros) my only conclusion is the Billion have really **** sheilding in their routers and was affected by the fluros.

 

Initially the ISP was telling me it was my T.V or video type appliances or the nearby T.V & Radio towers (nearby as in at least 10 km away)

 

Anyone else experienced anything like this?

I have a mobile tower about 900m up the hill next to me, dont think it does much...

 

router isnt near anything else, 1m to the nearest power boards and my pc.

Gruanch, Electical wiring Emits a Magnetic field which can indeed stuff with any data/communications cable/instalations close to it. Its relative to Current flow, so if you have data **** close to you're mains then yes chances are there could be some/alot of interferance. These days its actually illegal to wire Electricity next to data, and can cost the installer a pretty big fine per offence.

Yeah house isn't that new and the 2nd lounge is actually a verandah thats' been converted so it's possible that the fluros wiring could have been dodgy, the phone cable actually runs down the wall cavity and pops out next to a 240V mains socket that is also part of the room conversion.

Granted, but the respective wires should be adequately shield if there's a remote chance of main interference.

 

I'd be speaking to your cabling dude and asking him if he used shielded wires or not.

Generally in Domestic sites Installers don't use Sheilded cables due to expense and practicallity. the two main ways of seperating Electic with data is with physical barriers and/or distance.

For cables that there's no anticipation of mains interference, yes, but here in Canberra if there's a likelihood of interference, we use shielded copper.

 

At least that's what we did when I worked in TransACT and installed Ether and the TransACT cables. Not sure what other people do.

not so much wiring but sort of related. i used to have a microwave and fridge on the other side of the wall to my adsl router, this was then networked into another room to another router. the adsl router lasted 3 days then was shagged. funny how you realize only when its too late.

rig gal the wires that fixes everything , sounds more like bad plugs

florescent lighting generates allot of noise

when i say noise i mean the stuff that plays with the data in wires

and in my basic cable laying class i was told putting non shielded wires next to a fluro light is a big no no

but if you want to try a cheap way to defeat the noise produced by any thing electric

get some tin foil wrap it and then earth it

you must earth it or it will make it worse

Well having done some cabling jobs (i'm the lacky), shielded data cabling isn't used unless specifically requested by the client. However, we never put data cable within 300mm of an electrical cable due to interference as a rule. All data points should also be at least 300mm away from any mains power points.

No wonder our school computer system is so freakin' slow :disgust:

So really I should rip my connection out and run it elsewhere

Hmm.. So maybe my efforts at dropping cable down the walls had some flaws... Damn - saved some money though ;o)

I just used Cat 5e cable I think (bought 30m roll of it). Generally dont think I am within 30cm of power though, unless cable has slumped in the wall. Heck I even left a string tied up there to help pull other stuff through next time, was well pleased with myself!

lol that reminds me, back when i was at school and even where i work now you see power point, power point, data connection. side by side. ahh good old cheapo leckies. where would we be without them

Yeah, is a damn good idea to leave that string there for 'next time' (o:

 

Nother way of doing that is to undo the cable you've already run, tie string at the bottom end, then pull back up through the wall cavity, attach new cable then pull string to bring em both down. Had to do that a couple of times (o:

 

Re the 300mm rule that we work by, haven't seen anything written down anywhere regarding it (bloke i work with told me, he's been a rigger/radio tech for donkey's years), but is apparently done like that if you want your cabling certified to CAT6 standards. When i did cabling at TAFE they never mentioned it either, altho they didn't say much about the regs on cabling, think it was a filler course (o:

as a qualified cabler and krone master installer i could give you an 8 inch high pile of rules and specs about running data and other services. but ill just give you a few pointers. from the cabling rules

(AS/ACIF S009:2006) and electrical wireing rules (AS3000:2007)

 

1. any and all cabling (other that power (covered by different rules)) including the phone line, installed into commercial and residential premises must be installed by a qualified and registered cabler, and let me tell you there are big fines if you are not.

 

2. cables are to have a minimum of 150mm separation or a permanent rigid barrier from low voltage power cables (less than 1000vac/1500vdc) if not mechanically protected, conduit is a good mechanical barrier.

 

3. power and data points can be as close as you like if you have appropriate mechanical protection, a small plastic cover for the back of the points and some short lenghts of condiut usually do the trick.

 

4. lighting circuits must be separated from any power circuits.

 

5. the 300mm rule for separation from LV electrical servicesis not general wiring standard, it is a KRONE standard used to minimise interfearence it has just been generaly used by force of habbit.

 

6. shielded cable is not generally needed un less oyu are in a high EM area, shelded cable actually gives you worse performance even if installed correctly

 

as has been stated correctly above, all electrical devices, even hte cable in the walls have a electromagnetic field surrounding them, the more power or current the device uses the greater the field.

this can affect sensitive electronics like routers and comphters.

Fluro lights can create noise on an electrical circuit (but you shouldnt have tehm on a power circuit unless you have dodgey wiring.) they also have a much higher EM field than most other devices.

 

Try separating your phone/data wiring from the power cords under your desk.strong Radio wave interfearence can also affect sensative electronics.

 

I could go on for ever about all htis stuff. it takes over 2 weeks just to learn the basics of this stuff. and dont get me stated on fibre.

if anyon has any questions feel free to ask.

HMMMMMMMM 60, 000 VDC........Its warm and tingly.

 

Seriously if you go near Extra High Voltage Sub stations you start to get warm and tingly.

upgrade to Cat 7 cables.... or our cat 6a leads which are also shielded...

 

Nexans is the cable manufacturer... ask for them at local electrcal wholesaler.. Not sure...but, I think we have patch leads made for cat6a... cat 7 leads wont fit RJ45 ends... uses GG45 plugs..

 

Cat7 by the way is individually & overall screened pairs.. PS.. Nexans owns Olex..

 

From my limited knowledge guys... EM interference is everywhere.. But.. you are looking at a wiring fault if you get enough EM interference from some fluro's then I think the ballast is fudubilated.. or maybe under voltage (wild guess that!)

 

EM interference is mainly derived from variable speed drives & contained with shielded power & / or control cables..

As others have mentioned, fluorescent lighting is particularly evil. The reason your download sync speed can be affected differently to your upload sync speed is because the upload and download areas of the spectrum are at different frequencies (put simply) so the impact of interference will depend on its frequency.

 

You're probably best off running the router from a location away from the fluoros (and their cabling).

Hmmm now I'm starting to think that the fluoros are running of the mains power circuit at that end of the room (back room is converted verandah) thats probably not a great start. Might pay to get some one to come relocate the cable and set a new wall socket?

Graunch I am having a VERY similar issue to you (See here: http://forums.whirlpool.net.au/forum-replies.cfm?t=1068630)

 

If a phone is plugged into the VoIP port when it is powered on it will keep dropping sync, I have to plug it in after its synced.

 

Now that you mention this issue though I may try getting the phone cord away from power sockets and boards and other devices of interference.

From memory lights aren't meant to be on the same circuit as power outlets, but I could be wrong about that. I'm not saying someone hasn't dodged up such a configuration in your place though!

 

With the Billion in its working location, is it still plugged into the same phone socket as it was previously, or a different one? Is it a different power outlet?

 

Sounds like a different issue to me, poncho - either a hardware issue, configuration issue or compatibility issue with the phone. AJP's suggestions in that thread sound interesting (for you) though.

Easy to test - turn off mains, pull one fuse at a time and retest to see whether waal socket and lights come on together - they should have a different fuse if on different circuit... My dad's a lecky ;o) That's why we always had switches that we never knew what they did

Phone cable still comes out wall socket next to the power point, just cable and moden run 12 ft away from fluoros rather than right next to them. I think the Billion must sensitive, You say your having issues with a Billion router Poncho?
