well i dont know anything about it thats why i came for advice and not judgment here. However, what i get from some ppl here is-i told u its interference and u dumb didnt trust me,now enjoy with you low speed.
I tried to do everything u sugested and it didnt work so i went for reset. If there is an interference at 5ghz then i dont know how ppl get over 100 in other huge cities(apartment i live in is nothing compared to other countries apartments)...or they live in a small village with one access point?

Hey now, that was uncalled for. You're being very vague on your answers which makes you difficult to try and help. He raised a very good point here and it could be worth investing in.

And this is my 2000th post.

congratulations lol

and i also wanted to ask about the connection.so we have like a small black box with 6 wires coming out of it.they are wired to LINE Modem and phone.wires which are going to the modem connected to the small white box.and this white box is connected to the modem.I also have a phone directly connected to the point on the wall.is that right or something is missing/wrong here?bcz before phone has been connected to kind of a splitter and now it directly connected to the wall

Are all these speed tests being done from a wired ethernet device or not?

If there's nothing wrong with a wired test, you know it's Wi-Fi, the problem is that easy to solve and you could just be wasting time and energy troubleshooting a line (if it's yours and not the landlords or Chorus) if that's not the problem.

Why is there a filter hanging from a socket on the wall like that? If the filter was installed by Chorus at that point in an apartment and they consider the end of their network or apartment owners wiring (not the tenants) then I wouldn't be playing with it.

If the problem is the line, you probably don't have the right tools to be splicing the wires? So I'd leave it to a pro. If you're convinced it's Chorus' network, then log a job with them to check it. Yes it will cost if there isn't a problem with it.

But the first thing they are going to want to know, what is the problem, and if the words Wi-Fi are involved you're going to have to prove it's their issue unless there's an obvious problem based on their minimum standards on the line. But any tests would certainly not involve Wi-Fi full stop, that's none of their business.

speed test has been done from ipad 2 and galaxy s4.now i am using standart modem provided by telecom and dont use my dsl-n55u.The only modification i have done so far is changed to the first channel and switched off power saving feature.Also the modem is pluged directly to the power socket.I couldnt understand what sort of powerful radio things you were talking about and tried to find the answer regarding that in the net.However, all i find in the internet is about moving things which work on the same frequency away....all i have is a phone connected to the wall and i dont have other things which could potentially cause interference. My past expereince also shows that 5ghz is not stable and can provide different speed from 10 to 27(not stable at all and vary all the time).

Bigfox,

A bit more on the background of Power line modems, in case as you do not seem to be aware of them. Basically they do not use wireless but generate a very high frequency signal and radiate it along the internal power lines in your apartment. They generally are safe from interference as they do not "fight" for spectrum in the 2.4GHz or 5GHz bands. They do not travel from apartment to apartment generally because the switchboard to each apartment acts as a low pass filter and so a barrier. Easy to install- just plug one in at each end, also some come as a "master" and allow multiple slaves.

Your installation does look a little rushed, was it installed by a Chorus Tech ? I would have suspected he would have installed the master splitter in the wall behind the jack for safety and tidiness. It would be wise not the try swapping wires etc- you seem to have a good rate from Telecom so that part is obviously OK. It is reticulation of the internet around your apartment that seems to be the issue, and given the difficulty in finding available WiFi spectrum the power line modem way is how I would go ( I spend a number of hours with an Electrician running fixed Cat 6 cable right through my house). Your only other option I could see would be to put Wifi repeaters in a number of power points and "brute force" your way to higher bandwidth. But that would probably not make you popular with any other Wifi users around.

One other thing to consider is that there still is contention even if you are on VDSL - 30Mbps down and 10Mbps up is only as far as the DSLAM in the cabinet or exchange. You are sharing spectrum everywhere else -especially internationally- soon a Saturday Night don't expect total/much reliability of overseas feeds.

But you must understand, that's Wi-Fi, there's no such thing as perfect Wi-Fi, it's a free for to use spectrum interference and all by everything else using the same space.

Radio devices (such as access points) output a certain signal strength based on how much power is put in to the antenna (to keep it simple). Most only have a few 10's of millwatts RF power output. There are other's that have right up to 4 Watts (4,000 milliwatts like mine that got for miles). But the more pro gear generally isn't on the shop shelve or talked about among home users.

Here is a 1 Watt access point for example http://www.gowifi.co.nz/mikrotik-routerboard/mikrotik-integrated-solutions.html

They don't generally have a xDSL modem in them, so you'd connect them via Ethernet to your existing modem as they are more specialised routers/access points. That will provide a much stronger signal so would help blow interference out the window. But it could still be hit an miss if there's just to much demand on the spectrum being used in such a built up area.

You can try a higher gain antenna, might cost you $30 or thereabouts on trade me for a replacement high gain omni, or a directional antenna if your router allows a replacement external antenna. Or another whole access point with better radio chipset in it and more power.

But if any tests aren't being done via ethernet, they have nothing to do with Chorus.

It really sounds like you're stuck with what you have though. That's the nature of Wi-Fi. You might not get much gain by spending more money on it.

I don't see anyone calling names around and certainly not making it personal, so don't play that card. People are trying to help.

I never trust ANY speedtest over WiFi. Also different devices over WiFi will have different speeds - a laptop, a tablet and a phone all will have different characteristics even when connected to the same Access Point.

From what I see in this topic (and it's getting too long already), it's a wireless problem. The ethernet over power lines suggestion is not a bad one. Check it...

Sorry for confusion (I'm an ex broadcaster), I think in Watts mroe often than dBW or dBm.

You'll see in the spec sheet the TX Power section for say 802.11g, it says the max output is 30dBm. That's around 1 Watt or 1,000 milliwatts. You can google a dBm to watt conversion chart.

A cheap Netgear/Cisco home router or Belkin etc... only put out about 16 to 18dBm. It's not even half the output power, it's even less, under 100 milliwatts as dB is logarithmic not linear.

So a 1 Watt access point is much better at sending a strong signal than 0.1W. Higher output is better than higher gain antenna when in a bad interference environment. But it will also make it worse on other neighbours around you.

Bigfox: speed test has been done from ipad 2 and galaxy s4.

Both of which, obviously are connecting via Wifi. Your modem is syncing at ~34mbps down / 5mbps up. Your wifi performance is most likely the problem. You said in one of your earlier posts that when you tried "with a wire" - presumably a laptop connected via ethernet instead of wifi - that you got 33mbps on a speedtest. Given this information, Telecom can't fix it. This is getting repetitive and painful, and you seem to be getting defensive about people making suggestions, so I'm going to suggest you just pay some sort of on-site home support tech to come and help with your local network/wifi setup to ensure it's as good as it can be.

sorry just trying to understand everything you wrote to me.Thanks a lot for your help. Yes wired test i made on my desktop.my main testers for wi fi are s4 ipad and lap top sometimes.i use everything in order to make sure that its a problem with a signal and not with a net card in a device.

Which is good... But pretty much points out to be a WiFi problem now.

i want to get a power line adapter anf see how it goes.But what i cant understand is when u plug it in the wall it creates an internet circut in the wires?..And i can connect a tv to this power line adapter?And i also want to get a repeater for another room to make sure that my signal is strong.But this power line adapter will help me only if i directly connect something to it and it wont help my wirless signal?

The powerline adapters allow you to extend your LAN using existing power wires, instead of running ethernet. It's not IMO going to benefit your wifi, unless you need to use it to add an additional wifi AP for coverage reasons. It would allow you to, say, use ethernet -> power -> ethernet to connect a PC or other device via ethernet without running a cable through rooms etc.

thats a cool thing.So i can just plug a repeater in this power adapter and force other signals out?sounds like a plan=)do i need two of these things or only one?
