Repeater + Android 4.2.2 + Android web server
Hey guys
I have a stupid problem.. Mas that is the opposite of everyone else (so no Google can help me)
I want my android phone (my personal server) to connect directly to the router, and never to the repeater (the port 80 is blocked this way)
How can I do this magic?
Thanks

I didn't fully understand, but I think a quick drawing would help to get the overview of your setup and what exactly you want to achieve (who is connecting to which service, and so on)

Wtf is the repeater blocking port 80?
Shouldn't a repeater just... Well... Repeat whatever message is flying by?

If the repeater is able to block something, I guess it actually is a Router with Access Point.
Does your 'Repeater' show up as Device in the Main-Router?

So... Probably you have this setup:
You have one Access Point set up by the Router. Let's call that AP1.
Another Device (your 'Repeater') wirelessly connected to AP1 with one Wifi-Interface setting up another Access Point AP2 using a second Wifi-Interface.
AP1 and AP2 are configured to use the same SSID (WiFi Name), same Password etc.

If so... Just change the SSID of AP2.
Every other device will automatically choose the SSID with the stronger signal and automatically switch between the APs.
The Smartphone can be set up to connect only to SSID1 and therefore always connect to AP1.

Or go into the Settings of AP2, which probably is also just a Router like AP1, and forward Port 80.

I had to configure the router to allow the cellphone to foward trough port 80... I'm gessing that I can't access it from outside the network because the repeater is acting as the midle man (so the router assumes that the repeater is trying to use port 80)
BTW When that shit happens insted of accessing the site I get a download file, when I open it its blank or gives a error 502...
I can't access the repeater (unfortualy, that would be nice), and I don't know why, I just turned wifi off on the phone, then on, and its working again...
Guess that for some reason it connected to the repeater at some point during the night... and It's next to the router now. I'll see how it goes tomorow...
Or Ill just turn off the repater
but I bought the repeater so that my pa can access tha Internet from his phone, on the living room, so that's a no-no...
BTW repeater already has a different SSID. On my server I can't see it because it's android 4.2, on my Xiaomi A1 (Android ) I can see both, and the repeater ads _5G (wird name, but still)... so that wont really work...

Frustrated... I want to share my page with my colleges, so that they get motivated to give me their own tool tables...

Btw, the page is http://rjpf.ddns.net/ If you want to check it out, I'll be glad to accept tips, since I'm again noob in Html, just learned CSS and I didn't even pick a color pallete yet

@2erXre5 'll try to give all the details
I have a cellphone, Alcatel Pop7 4core, 1gb ram with root
I have a server app (Ultimate Servers Pro) with a DDNS updater, a web server (lighttpd, static)

I hate a router that connects to the internet (cable and wi-fi)
On the server config I configured the cellphone to use port 80 from the outside

I have a repeater , two rooms from the router
When it is on the server (cellphone) can't be acessed to the ouside.
When I turn it off I can access it from the outside

The cellphone, because it's android 4.2 doesn't show different SSIDs for the router and the repeater, both will show the same name when connected.

Best solution: Force the cellphone to only connect to the router

And... that's where i'm suck, since google resolts are for people who can't connect to the repeater (the oposite), actualy had another cellphone that doesn't connect trough a repeater, so I understand their problem.

I usualy like to search for this kind of problems, I learn a lot more then just asking, but since i'm stuck.... HELPPPP!!!

@RodrigoF ok, now I get the picture. it seems that your repeater is doing some kind of NAT or has even a firewall in place. ads_5g means probably 5ghz network. Is your WLAN which is propagated from the router also on 5ghz or on 2.4ghz? If it is on 2.4ghz then the repeater might have its own network segment (running on 5ghz) where you are only able to go one way (from 5ghz to 2.4ghz to internet and not the other way round). in that case you can only try to give a separate SSID for the repeater network and drop that SSID from your cellphone config, so that your cellphone connects with the router's WLAN only.

@RodrigoF
The _5GHz doesn't have anything to do with the differentiation between "Router" and "Repeater".
It just means that one Device (probably the "Repeater") spans up two Wifi networks one with the usual SSID and the other with SSID_5G.
It uses a 5GHz Wifi module for the second one, which increases speed while decreasing range. 5GHz is pretty common in newer phones but uncommon in older/cheap devices.
@2erXre5 already explained that.

So... I'm guessing the "Repeater" is not just a dumb device which will send out every package it gets in (one repeater repeats every network in its neighbourhood), but a Router configured to connect to the main Router as Client and setting up a own Network again.
If you can't access its configuration, how did you specify the Network it should connect to?
What Model is the Repeater?
Can you access the Webinterface of Router 1, if you are connected to the Repeater?
If you can, make sure you are connected to the Repeater and do a traceroute to Router 1.

I connect to the router trough rj45 (3x the speed)
The repeater is a 300mbps TP-Link , To configure I plugged a rj45 to it, and the only config is to pick the SSID of the router and password (no other options)
It's cheap for a 300 mbps router , and works really well for the price.
have another one, another Tp-link 150mbps but phones won't work with that one, so I don't use it

@2erXre5 First thing I tried was to drop the ssid of the repeater, but on the cellphone it only shows the ssid for the router (it connects to the repeater but shows the same SSID)
In my new phone with android 7 I can pick one or another, but not in the 4.2 Android server
Btw, the trick worked

I first moved the cellphone next to the router, so it would only connect to it, but bugged the next day;
That night I turned off wi-fi and on again and didn't connect to the repeater till now
My first problem was to not reset the wi-fi when I moved it, with luck it will stick like this.
Still, there must be a way to only connect to one SSID (router) or not connect to the repeater...
Right now, and if it sticks (continues to not fail) I'm still interested to learn how to do It...

Btw sorry for the mistakes and misspeling.... Burnout + Overwork and I've been in ZombieMode for a few days

As you explained:
You connect the Repeater to the Router using a Ethernet Cable.

This means the 'Repeater' doesn't connect to the router via WiFi and therefore doesn't need to know the SSID of the main router.
This also means, it can't be a real repeater (device which aplifies WiFi signals), but is a completely separate Router/Access Point on it's own.
You can set the SSID via some interface. You don't need to set the same SSID, as the main-router uses.
Just set another SSID.
Like... Append "_2" to the SSID of the second router. Then you will see three WiFi Networks. One with the usual name, which will always connect to the main router directly. One with '_2' appended and probably one with '_2_5G' appended, which will both connect to the second Access Point ('Repeater'). If you connect your phone to the usual SSID and don't save the other SSIDs in the phone, it will always connect directly to the main router.
Every other device should know all three SSIDs to switch automatically.
