Hello to all!!!

I am facing instability problems with my wireless network! My setup is as follows:
There is an ADSL modem (ZXHN H108L) located in a building. My TL-WA7210N (access point mode) is located at the roof connected with 20 meters of LAN cable to one of the 4 free ethernet sockets
of the ZXHN H108L. The purpose of this setup is to give access to any device (smartphone and/or PC) to the internet within a distance of 200meters. Unfortunately the network
cannot operate continuously with out problems. Frequently, there is limited access and no connection to internet of course! There are times that i am not even able to access the
TL-WA7210N typing its IP address in any internet browser.
Following i am attaching some photos to give you an idea of the setup!

First setup of the ADSL modem:









Setup of the WA7210:
















Any help will be greatly appreciated!!

On this picture you need to shorten the dhcp pool of your main router change 253 to 200

On this picture you can see you are using 253 as ip and if you had changed, you where using a number in the dhcp pool and that's wrong
Disable IGMP proxy too

You mean the connection is always unstable? or it becomes unstable after a while?

Try this beta of new drivers.

Also I need to mention communication is always bidirectional. If there are obstacles in the way it is hard for the smartphones/clients to talk back to the AP.

Seriously? That's quite impossible as smartphones etc. just don't have the output power to be "heard" by the access point.
The devices "hear" the beacons of the access point and try to answer thus disturbing each other.
With smartphones you can barely span a distance of 50m.

If you know a magic way to make this setup work please tell the Freifunk community...

This is the classic answer you read at UBIQUITI forum, sounds copy & pasted
In the particular case of 7210, I had (now is replaced by a CPE510) one set up as AP, distance, 778 mts. and in those days I had a IPHONE 4, a Dell Laptop and a iPad 2, with the 3 devices I surfed Internet from my daughter balcony, signal 3 bars, surfing wasn't fasr,
Note: a year before with a 5210, it could be done too.
200 mts for 7210 it's a piece of cake.
If you ask me if today with 510, I still can do it, don't know, cause MAXTream is enabled

I've developed a software for visualising and interpolating 2.4 and 5GHz wave propagation, am a ham and Freifunk activist. I've never experienced anything that comes close to what you describe with ordinary consumer oriented hardware. Yes, we did 30km+ links, but only with directional antennae and 1W with 20db+ antenna gain.I must admit that I've never performed measurements in an environment without radio interferences. But really?! A stable 700m+ connection with an iPhone? There weren't any cell phone towers or other wifi networks around, were they?

I posted surfing wasn't fars (meant fast) you posted stable
That 778 mts is a link, when ever I went to her Loft I tested with my iPhone 4 the connection and all worked
Give me some days, now I'm in my high season (school endings) my business is photography, and this year is a great one, once it finishes I will disable MAXTream on 510 and with iphone 6 I will replicate the test and post screenshots and pictures of the link.
I will let you know in this Thread, and will send you a PM let it you know the update.
Never seen you here before its your 13teen post, Wellcome, people like you it's what this forum needs, hope you stay long.
