WAP broadcasts wifi all the time?


[link to this post]
 
I have a TPLink WAP. Should the WAP broadcast the same wifi signal strength no matter if it is connected to a router or not?

I can see that without connection to a router it would not broadcast an internet signal but am I wrong to expect it to still sent out a wifi signal. In othet words if I only want it to link just my home devices should it do that? Devices are a Galaxy S5 phone and Google Chromecast Audio on same 5G wifi network.

A WAP should be able to be used independently of a separate network. However, it would need an IP address (set the WAP to a static IP) and either the WAP would need to offer DHCP for the clients or the clients would need static IP addresses set in the same subnet as the WAP. But, doing that it should be possible to create a full private network without any other equipment.

Thank you.
I am not sure I understand all you said but will continue to experiment with WAP/Poweline units to get a reliable signal to my Chromecast Audio. I actually need internet because I both stream ftom the internal micro SD card and stream from apps on my Galaxy S5.

Sometimes the Audio stays connected all day, other times it drops every half hour or so; WAP stays in same pkace all the time.

The IP address of all your devices comes from the main router, so say I link my WAP to a BT HomeHub, when I connect a device to the WAP, the device gets its IP address from the BT HomeHub, not the WAP. In the absence of the BT HomeHub devices do not get an IP.

Some devices may have additional options and functionality, but a WAP is generally linked to a main router of some sorts - and best to stick with that.

If linking your WAP via powerline please stop, run an ethernet from your main router to the WAP, do it right it'll save you a potential headache down the line.

I understand not using Powerline; use cat 5 instead BUT her indoors will not accept more holes!! I should have put cat 5 in the listenening room before I last decorated!!

So you actually do want it connected to the Internet? If that is the case then my post isn't relevant - you seemed to be suggesting you wanted to create a private network without external connections but I may have misread it.

I would expect it to broadcast when powered up regardless of any router as that would allow two wifi devices with fixed IP addresses to communicate.

Depends on the AP, some APs are setup to disable SSID broadcast if they lose contact to the main router / wireless controller, this is setup so a bad AP does not mess up the overall network (e.g. imagine you had 100 APs) over a large area, you'd rather users fallback to a further AP than one with no connection out.

[re: ukhardy07] [link to this post]
 
My reason for askjng this question is because I am getting dropouts from the Chromecast Audio(CA). So I thought it would be worth asking firstly if the WAP would broadcast wifi without intetnet connection. I have now tried with the internet cable removed from the WAP but cannot get the CA to work via that setup.Noted the reference to a WAP not working if no internet connection. Will have to see if my TPLink AC750 is like that.

I have had the CA working faultlessly for over two days but since it dropouts a random times; maybe evey couple of hours, sometimes in 30 minutes or even much shorter.

One thing I have noticed is that 5Ghz seems mord reliable that 2.4.Also the distance between the WAP and CA does not make that much difference, in fact the over two days was with the WAP in the next room, seperated french windows

One thing I may be able to do is bring an ethernet cable near the CA; at present to be near the CA I have to use Powerline.

Powerline are notorious for dropping out.

You have a main router - powerline - access point - wireless link to chromecast audio

The chrome cast audio is getting an IP from the main router, when the powerline link fails it will drop out.

Just to rule out a faulty chromecast audio, if you connect it to the main router not the access point do the issues go away? If they do, the issue is the access point, and most likely those powerline plugs.

Note I said if you are linking over powerline to stop and run a cable, these kinds of issues are exactly why I said that. In some homes they work fine but in a lot of homes they are a nightmare.

No, a typical WAP will not let you talk to all other devices on the network without a connection to the router. Some may be able to do this, but then they're more than just a standard WAP. You might be able to get it working via Static IPs - but I'm not sure if that's something you'd want to try?

There's a difference between connecting to the router, and connecting to the internet. As long as you have a router connected up, everything should be able to talk to each other and you won't need an internet connection. To this extent, you could get rid of the WAP and get a cheap wifi router to replace it as anything connected to this wifi network will be on the same network.

Without knowing any of the finer details and knowing the reliability of powerline adapters, the dropouts could most likely be related to the powerline and not the WAP itself.

Then I'd do that, and then buy the Ethernet adapter for your Chromecast Audio

Davey_H that looks like a good solution. Getting the ethernet to the CA will be bit of a pain and will involve a long cable but do able.

Will buy unit and report back when running.

Why are you bringing Ethernet to the chromecast audio?!?! THE Chromecast Audio can connect over WiFi as intended.

Just link the access point via Ethernet, putting the AP close to the chromecast and let the chromecast audio connect via WiFi as intended. Itís not designed out the box to use Ethernet thereís no need.

With this setup all devices can benefit the improved WiFi coverage from the access point.

As was said earlier better to plan for the future e.g. a new receiver (current amp has developed a problem that may not be solverable) that has built in Chromecast that also had ethenet input.

I have in fact just setup my WAP as you suggest; WAP now along side CA with ethernet plugged and CA using now improved wifi. However wifi in the area the WAP was, is now poorer; my summer listening maybe affected; WAP was there to give better/useable wifi in conservatory.

I had assumed your chromecast received a good signal from the AP, if that was the case switching the location of the AP to beside the chromecast should give a good signal in the original AP location. Itís now just sending it back to where it originally was.

Given you have moved the AP besides the chromecast, and now WiFi is poor where the AP originally was, this must mean the signal from the original location to the chromecast was also poor.

You may have just identified the issue all along.

The chromecast audio has very weak internal WiFi and you need a good signal to it.

You need to ensure you connect the APs with Ethernet for best performance and that signal is adequate to the chromecast. Ideally ensure -70RSSI or better throughout the property.

Your issue generally sounds like you have inadequate WiFi coverage around the house, and connecting with homeplugs isnít helping either.

If you inagine all traffic must go via the original router, you donít want a slow homeplug which may drop out in the middle, unless you know your home wiring is perfect.

Connecting the chromecast audio with Ethernet is just a band aid, hiding the fact the WiFi signal is inadequate in that location, fix the real issue which is poor WiFi. What happens when you want to add something else like a smart tv or new technology in future, or perhaps use an iPad in the weak signal area? Itís much easier to hop onto a good WiFi network, for example I can get 400Mbps all over my home on wireless, so I donít need to wire anything in. I have 4 access points around the home, and I use a mesh wireless network similar to the BT whole home wifi (its an option for you, itís wireless but expensive). What Iím saying is once you get it right it just works.

[re: ukhardy07] [link to this post]
 
Thank you all for the advice.

Ukhardy07

My way of measuring signal strength is by the Andriod app Wifi Analyzer; I realise that this app is not a real meter so only gives a guide. However at the WAP I get - 50dBm which the CA can now use. But in my conservatory I am getting under -70dBm.

Whether I will ensure good hifi coverage all over the house depends on my future plans for high tec TV etc. My wife's cinema room (sounds posh but just back bedroom with large screen and surround sound) is the site of the Virgin Hub 3.0, so she has very good wifi there. That room is the most likely to have a more high tec TV (being researched now) than our lounge. Lounge being my domain and, being a miserable so and so, I rarely watch TVsmile

Provided youíre closer to -70 and not -80 it should be ok!

I checked this morning and on my tablet still just touching -70 but my phone, which I use to feed the Chromecast, is just over -70; but as I said "meter" is only an app.

Last evening Chromecast and phone stayed connected for over 5 hours.

Thank you for helping me and a Merry Christmas.

I should hsve said which ethernet device I bought; this one:-

Works well i.e no unexpected drop outs
