In reply to a post by RobertoS:
I always fix my channel at a low combination point of the surrounding signals. I don't see the point of setting it to 1, 6, or 11, ever. Unless I'm mistaken, I am fixing my strongest signal away from all other strong signals.

Doesn't always work, as the interim channels are affected by someone close by on 1, 6, 11.

I had WiFi in my flat in 2002. Nobody else on the entire estate had WiFi. Now I have to live with neighbours with faulty routers that keep moving channels on top of what ever I select - and the solution for me is 5GHz as it solves the issue in my flat, and only just reaches my bedroom. Hopefully my neighbours are far enough away even if they get 5GHz, I will keep working.

Many phones and tablets don't yet support 5GHz, and often only the more expensive laptops do - but this is changing fast. (the iPhone 5 is the first iPhone to do 5GHz, but ALL the iPads do back to the iPad 1 for example).

Yes, I agree re the overlap. I always assess this before choosing, using the 2.4GHz graph you just referred the OP to. That's the most useful part of the display, in my opinion, as it's very quickly obvious which stations are the ones to avoid as their signal strength fluctuates.

The problem with any fixed channel is of course that a lot of the surrounding ones move around afterwards. So it isn't a one-off exercise anyway. It needs regular review.

Yes - and you need to do performance testing, as many networks are transmitting 24x7 but used very infrequently, or for low bandwidth uses. I moved to 5GHz when my neighbours started using their connections more than for web surfing/email (I assume streaming video). I had a performance fall of 50% (speedtests, and downloading large files)

Yes, which is why I advised the OP to buy the Mac app.

kasg, what a patronising post. Clearly you are knowledgeable about computers and networks, however I am not and I suspect neither are many people who come to this forum to seek advice. As others have already highlighted I was incorrect that it was the fault of the ISP which I was pleased about.

However, thanks to the users who have actually replied with helpful posts. I actually don't live in a block of flats, but a semi-detached house on a fairly new build housing development. There are lots of houses in close proximity to my house which must be why there are so many wi-fi networks showing. I've taken your advice and invested in a pair of home plugs, and I now get speeds of 45mbps on my computer upstairs smile This obviously doesn't solve the wireless issue for my other devices and I will consider investing in a 5ghz router.

One option if friendly with neighbours is to try and co-operate to experiment and find the optimum setup for everyone, e.g. what arrangement of wifi channels gives everyone the best speeds. Or if a home does not actually use the WiFi at all to turn it off and remove a little more interference.

In theory the 5GHz band has more channels, so should avoid the congestion issue for sometime.

Even for those of us who struggled with the first 802.11b routers years ago, Wi-Fi and what works best is still an experiment as each local situation is often very different e.g. some people have poor range simply because they have foil backed plasterboard, or a neighbour using a video sender.

Agreeing generally with most of the suggestions, can your Router be set to AUTO to automatically find the best WiFi Channel?

Regarding a 5 GHz Router, basically most of not all of your PCs etc will have to be equipped to work in that band. If not, you will have to ensure that the new Router will work "simultaneously" on both bands. Apparently some do not.

I believe there are other complications such as although the "new" Router is capable of working in both bands, it will automatically restrict itself to the lower 2.4 GHz band if any other device in your network is using that band.

As others have mentioned, the 5 GHz band generally does not give as wide coverage as the 2.4 GHz equipment.

"Laws of Physics".

5 GHz is nearer the frequency/spectrum of Light, so has greater attenuation going through walls and such-like.

================================

As well as Video Senders mentioned by Andrew, there are several other types of devices that all share the same radio spectrum/frequencies as the 2.4 GHz WiFi - BUT these do NOT show up in WiFi detection software such as basic, free, inSSIDer.

What may look like an unused or quiet part of that spectrum, may be due to all the other Routers in the vicinity are avoiding that Channel, as they are set to AUTO.

That is, what is apparently the quietest part could in fact be from a radio aspect, the noisiest part of the 2.4 GHz allocation, hence the worst to attempt to use.

Rather like trying to have a two-way conversation in a noisy environment, whether that noise is arising from others also trying to engage in their own conversations; or there are other "noise" sources such as muzak, vacuum cleaners etc.

There are other, non-specific devices which can also cause problems, such as plasma-screen TV sets.

The OP seems to have mostly apple kit, so it is likely to have 5GHz WiFi built in. The iMac will have (My mid 2010 iMac does as does my mid 2007 MacBook Pro). iPhones prior to the iPhone 5 do not.

I use an Airport extreme in my BT Infinity setup instead of the HH3 (simply because I had it already), it is expensive but does work and is simultaneous dual band.

In reply to a post by R0NSKI:
What he eventually found was that if he put the wireless router in the lounge he instantly got better speed, put it back in his office and the performance plummeted. He still has no idea what's causing the problem when the router is in his office.

Radiation pattern of router antenna(s), metal in path of signal when transmitter is in office, location of receivers, orientation of receiver antennas and their receiving pattern etc

My recommendation would generally be to try a dual simultaneous band 5GHz router for anything that needs to be wireless, twinned with some fast powerline adapters for anything fixed. In terms of routers, I'm a big fan of Apple's ones and they're stupidly easy to set up, though The Wirecutter like the ASUS RT-N66U. When it comes to powerline adapters, while I haven't used them myself, considering all the reviews I've seen, I'd go for these ones from Solwise myself.

Some do work, but some (such as the VM superdud) have a habit of all SSIDs ending up on the same channel. (It HAS to be bug, but I've watched my neighbours dance around the channel numbers for the last year).

Regarding a 5 GHz Router, basically most of not all of your PCs etc will have to be equipped to work in that band. If not, you will have to ensure that the new Router will work "simultaneously" on both bands. Apparently some do not.

The rubbish ones (e.g. draytek) are switchable. The original virgin media superdud is switchable. Anything modern is simultaneously dual band, and the best third party ones seem to be the around £85 TPLINK or the £100 ASUS. (I went for the ASUS before I learnt about the TPLINK).

I believe there are other complications such as although the "new" Router is capable of working in both bands, it will automatically restrict itself to the lower 2.4 GHz band if any other device in your network is using that band.
Sounds like a non-simultaneous unit - the ASUS has two separate WiFi lights and two separate SSIDs for 2.4 and 5 GHz.

As others have mentioned, the 5 GHz band generally does not give as wide coverage as the 2.4 GHz equipment.

Even in my small flat, where my router is situated right in the middle, I can have reception problems on 5GHz at the edges. This is good for usage in the same room, and not interfering with neighbours though!!

There are other, non-specific devices which can also cause problems, such as plasma-screen TV sets.


Yes, I agree with your points - and a WiSpy/Channeliser that can pick up the microwave ovens and other transmissions would be worth renting for many people smile
