E4200 as a Access Point - Won't Work

    hi there,

    I have a linksys E4200 (Ver. 1) connected to my wired router at home (my main router) all i want is that the E4200 will act as an access point, to wireless clients.

    This is the Version i have:

    Code:
    Tomato RAF
    Version 1.28.9014 series (Beta)
    * BY the way, is this a recommended version?

    So after reading here on the forum, i set up my router as the fallowing;

    Wireless settings;

    - and the E4200 is connected to my wired LAN like said,,
    everything seems to be set up ok. but clients are unable to connect.
    I see the SSID on my Iphone. but unable to connect..

    Ensure DHCP is disabled on the E4200.

    E4200 Should be connected to the gateway router through LAN port or you need to select Bridge WAN port to primary LAN.

    In the routing section, change from Gateway to Router.

    Change both routers to 20MHz channel width. If you are dead set on using 40MHz, then at least make sure one device is on Channel 1 and the other is on Channel 11.

    Hi,

    Yes the E4200 is connected to to the gateway Router Via LAN Port #3. (the Gateway Router is in the 1st floor)
    the E4200 is on the 2nd floor.

    I set up like u said in the Routing Section from gateway to router.

    [​IMG]

    When i am on the 3rd floor (in my house) and try to connect Via my Iphone (Using Wireless).
    i see the network but i still unable to join.

    here is a a bit more information.
    my main router in the 1st floor, is also an access point - it works fine while i am in the 1st floor of the house. the SSID in both Routers (Main gateway + E4200) is the same name.

    The Channels - Should i use in both routers 20Mhz. a Friend of mine recommended that i use 40Mhz and in each router choose a different channel (Main Router Channel 1, E4200 is channel 6)
    Is that OK?

    Use different SSIDs or use WDS instead.

    Can u Please explain ? what is WDS?
    i prefer that it will be the same SSID, instead of changing the WiFi network every-time i go upstairs ..

    This is not an appropriate situation for WDS. It's an AP wired to the primary router/gateway.

    40MHz channel width should be avoided, especially if you are using channels other than 1 or 11. Switch both to 20MHz, scan for nearby networks, and choose channels 1, 6, or 11 based on the fewest adjacent channels in use. If your wireless environment is crowded, it's sometimes better to choose the same channel as a neighbor than choosing an overlapping channel. (eg. Neighbours on channel 3 and 11, you may want to use channel 11.)

    As a troubleshooting step, change the SSID on the E4200 and see if you can connect to either router and, if so, where in the house each one works. There could be issues in the configuration of the gateway, AP, or client. Separating the SSID may point us in the right direction.

    Almost forgot, on the advanced wireless settings, change E4200v1 to region Singapore and transmission power 0 (hardware default).

    Hi Marcel Tunks and Thanks for your help.
    so there is some development,
    First i changed like u said to 20Mhz. - i was able to change it only on the E4200, there was no settings in the Main Netgear Router.
    this is a screen shot of the E4200, after i scan to networks;

    [​IMG]

    I am not clear what Channel i need to choose. The SSID of the Main router IS Vaknin (as u can see in channel 1- that's what the main router is using)) and i gave the E4200 another SSID name like u said (Which is named Vaknin1)

    For the time being i choose channel 1, and disabled security.

    after doing that, i am able to connect :)

    Now.. Is there a way i can have the same SSID ?
    the main router is for the 1st floor of the house.. and the E4200 is for floors 2+3..

    you certainly should be able to set the same SSID.
    are you using the same security on both routers? remember, WPA2+WPA is not the same as WPA2.
    you can use either the same or different channels. n my house, i have mulitiple access points on the same SSID and channel. clients move between them with little difficulty. when a client switches accesspoints is somewheat unredictable; most wireless drivers allow you to set a threshold to keep a signal or drop it.

    what is your main router? In my experience, clients connect preferentially to atheros-based access points, even if a broadcom one is closer and has stronger signal. There may be client-dependent negotiation issues that make broadcom connections a little slower. you might try turning off your first floor access point temporaily to reduce interference, and then make sure all your clients can connect to the E4200 when there is no compettion.

    HI,

    things are really weird... i have some problems i just can't understand..
    i will tell you about the network in my house;
    So i have 3 floors in my house. on the first floor i have my main Router, that is also a modem (Build In)
    it's a Netgear VEGN2610. -
    Basically - clients on the first floor connect to the netgear.
    on the second floor i have the E4200 that is connect wired to the Netgear downstairs. so clients on the 2nd and 3rd floor connect to the E4200.

    you can see from previous screenshots How i set-up the E4200.
    when i try to give the E4200 the Same SSID as the netgear. and also the same security:

    On the Netgear it's on WPA2-PSK [AES].
    And the E4200 is on WPA2 Personal \ Encryption: AES

    *Both Security settings are the same as i understand..


    But i'm unable to connect to the wireless network, my Iphone says "unable to Join" and on my laptop it says "Unable to Authenticate"

    - i have another problem that after several hours suddenly devices can't see each other.. and only a reboot to the main router will fix it..
    but for now it's more impotent to fix the wireless problem..

    i don't know anything about your main router, but when i had a netgear as my gateway with stock firmware, i had to do frequent reboots.
    some questions:
    1. do you have qos or transfer limits on your main router? if so, maybe you are maxed out.
    2. are you sure the netmask is 255.255.255.0 on the netgear? the default netmask for class A networks os 255.0.0.0.
    3. are the IP addresses of your access points excluded from the dhcp region for your main router? what i mean is: if your AP is 10.0.0.2, and your main router hands out DHCP addresses over the range 10.0.0.2 -10.0.0.254, then you could get a conflict when a new client gets assigned the same IP as your AP.
    - there are two ways to remedy this:
    - change the DHCP range on your main router
    - assign a fixed address to your AP's using DHCP reservations.

    that's all i have for now.

    My netgear is a special edition like that was created for my ISP.
    so the netmask is 255.255.255.0

    [​IMG]

    the E4200 is outside the dhcp - with the address of 10.0.0.2

    the QOS is off.

    I am going to try to give the E4200 same ssid as the main router..
    maybe disabling the broadcast of the ssid on the E4200?

    And another question;
    should i enable here STP?

    don't enable stp.
    don't disable ssid broadcast.

    did you try disabling wireless on main router to see if you can connect to the AP at all?

    I don't know what just happened.. but it's working now..
    i changed the ssid on the E4200 to match the one on my router.
    re-insert the security settings, went upstairs.. and walla! i am able to connect..
    i see the signal is excellent.. so it must be the signal from the E4200 one floor down..
