Why can't ZTE BLade connect to 802.11n?

[Guest GoodGosh]

Hi there, I was messing about with my wireless router and I heard that 802.11n is the most secure protocol so I changed the settings from 802.11g/802.11n to only 802.11n.

Then when I tried to connect the phone it just kept saying connecting.....disconnected over and over again.

Does the phone only work on 802.11g?

Thanks for any advice

Doesn't have the hardware to do it, it'll only work on b and g networks (possibly a too, but not seen one of them in a while!)

I'm not sure about 802.11n is the 'most secure protocol' - I could set up an 802.11g network with a 63 character randomly generated ascii key and secure it with WPA2, then I could set up an open 802.11n network beside it. Which is more secure?

I have my blade connected to a 802.11n router, but the blade lacks the hardware tp recieve the highest speeds, the fastest i've seen my blade is 7Mbps on a 50Mbps line.

the 802.11n structure for wireless is more to do with the speed that it can support not the security of your wireless. Too increase security make sure you use a WPA2 key and maybe even disable SSID broadcasting.

a/b/g/n refers to speed, I think, with wifi-n being the quickest. Wireless security is based on whether it's WEP, WPA-2, WPA-TSK (AES) et cetera. Most electronics use wifi b or g.

It only has a 802.11g chip in it, therefore it will never be able to connect to a 802.11n network. - Change the router settings back.

More Secure... nope, just that it generally operates on a higher frequency this gives the *Selling Point* (not fact) that it is more secure... as technically speaking, there are less receivers for it's signal out there which can be portrayed as being more secure. And less interference with other devices, therefore again... more speed/coverage. (devices with older 802.11n such as the draft/draft2 operate on the same frequency as 802.11g)

The encryption available over each signal range is the same, therefore the real level of security is exactly identical... really the only difference, is speed and coverage. (Full 802.11n having a kicker speed of 400mbps and about 40% more coverage than it's 802.11g/n-draft partners)

Hi guys, thanks very much for the information. I understand now that it's the WPA2 key that's the most important for security and I switched back to 802.11g/802.11n

I also took your advice and unchecked the SSID box. My phone couldn't find the network then but I manually added the SSID name and then it connected no problem. I take it that is how it is meant to be set up.

Do the Wireless Channel, Extension Channel or Bandwidth settings matter much?

Thanks again for sorting me out :)

yes g or n has nothing to do with security

my blade at home is connected at 54 meg bits (802.11G)

wpa2

i haven't tried to connect it in N because the hotspot is limited to G

if someone succeed to connect the blade in N would be great to know :)

I think I have... my router is an N router and the OSF connects to it perfectly - I doubt that the settings are changed to g speed... I'll have a look and report :)

802.11n will provide speeds of up to 300Mbps - note the use of the phrase up to. That means that if you have other wifi equipment that is also 802.11n compliant, they will work together to give the max speed. If, however, you have an 802.11n router but only 802.11b (11Mbps) or 802.11g (54Mbps) clients, the router will "downgrade" itself to work at those lower speeds - but it will work.

-- Presuming they are on the same signal, a 802.11g client won't see or connect to a 802.11n network in most cases... as they are simply trying to communicate on different levels. (The exception here is 802.11n Draft routers, as they are using the same signal frequency and bandwidth 802.11g)

802.11g = 2.4GHz @ 20MHz

802.11n = 5GHz @ 40MHz (2.4GHz @ 20MHz for Draft/Draft2 Devices) -- You can also use upto 4 streams with most of the latter 802.11n routers compared to just one with 802.11g, each stream having a rated throughput of 150Mbps (so the max in theory is 600Mbps, but I've NEVER heard of anyone actually achieving this even at point blank -- The Sorcerer is correct in saying 300Mbsp, as most clients only use dual stream... I'm yet to see a quad stream client)

This is why some routers come with both 802.11g and 802.11n, if all 802.11g clients were compatible with 802.11n then what would be the point of sticking the extra chip in... would just be wasting their profit margin there.

You'll have it set to broadcast a mixed signal. So it can connect to devices using different wifi protocols.

...

Most definitely, if there are multiple routers all using the same channel then the signal will become very degraded due to all the interference so take a look at what networks you have in the area... and pick a quiet channel to use.

Bandwidth will directly impact on speed and coverage (see the chart on the wiki page in my other post, and it'll pretty much clear that question I think)... however there

s no point setting it at 40Mhz~ if your client can only reach 20~, you'r router's signal might be blasting away down to the local pub... but that's not gonna do you any good if you can't even connect to it sitting on top of the box :)

I stand corrected - my router (Linksys WAG325N) is a Draft n which is probably why it can see the various other b's and g's.

So do I, http://justinlee.sg/2011/04/08/linksys-e42...e-in-singapore/ -- triple channel and therefore 450Mbps max, not quite the 600Mbps theoretical max... but still.

And I only have the Linksys E3000 :) lolz

Its strange but you'll have it set to broadcast a mixed signal. So it can connect to devices using different wifi protocols.

Hi Stephen J. Knill, thanks a lot for the excellent info. Sorry for one more newbie question but regarding Channels, when you said check what networks are in your area what does that mean please?

[Guest ColdEmbrace]

Hi Stephen J. Knill, thanks a lot for the excellent info. Sorry for one more newbie question but regarding Channels, when you said check what networks are in your area what does that mean please?

You can get a tool which scans for your local wireless networks and picks u the best channel

[Guest Stephen J. Knill]

Hi Stephen J. Knill, thanks a lot for the excellent info. Sorry for one more newbie question but regarding Channels, when you said check what networks are in your area what does that mean please?

Majorly late response... as ColdEmbrace mentions above you can use an app for this, I suggest using "WiFi Analyzer" which is freely downloadable from the Android Market.

The reason that this is advised is so that you can see what channel other networks in your area are operating on, this way you can pick a "free" channel to avoid signal interference (which will greatly impact speed and performance of BOTH networks). -- The App mentioned above is capable of telling you what channel is best to use.

... Hope it still helps, someone :P
