[HELP] [REPEATER - RB951ui-2hnd] only Laptop can get DHCP, smartphone not

RouterOS Wireless Networking

Hi Everyone,

I have a RB951ui-2hnd and it was configed as repeater.
My Laptop can connect and get IP, but my smartphones (Android, iOS) can’t. What do I need to check ?

Thanks for your support.

Check WPA/WPA2 and TKIP/AES support in your smartphone.
Maybe you need to reconfigure WiFi settings to common denominator for laptop and phone.

Hi,

I’m facing pretty much the same problem: I use a mAP 2n as a repeater and no smart phone or tablet gets a DHCP adress from the DHCP server, allthough the Laptops do. The WLAN connections of the mobile devices to the mAP 2n work, the log in the mAP 2n shows the successful WLAN connection of the mobile devices. If I “torch” into the base WLAN Interface I can see the DHCP broadcasts, but no reply at all.

I’m out of ideas. Is anybody out there, who already solved this problem, can give a hint or give some guidance where to proceed with the problem analysis.

Thanks in advance.
Frank

Hi,
here’s the export for the “interface” tree:

/interface lte
set [ find ] mac-address=0C:5B:8F:27:9A:64 name=lte1
/interface bridge
add name=br-Home
add name=br-WLAN
add name=br-dummy
add admin-mac=6C:3B:6B:20:E9:87 auto-mac=no name=bridge
add name=bridge1 protocol-mode=none
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
add authentication-types=wpa2-psk eap-methods="" management-protection=\
    allowed mode=dynamic-keys name=Home supplicant-identity="" \
    wpa2-pre-shared-key=secret1
add authentication-types=wpa2-psk eap-methods="" management-protection=\
    allowed mode=dynamic-keys name=DMZ supplicant-identity="" \
    wpa2-pre-shared-key=secret2
add authentication-types=wpa2-psk eap-methods="" management-protection=\
    allowed mode=dynamic-keys name=Game supplicant-identity="" \
    wpa2-pre-shared-key=secret1
add authentication-types=wpa2-psk mode=dynamic-keys name=\
    InternetWLAN-DownUnder-repeater wpa2-pre-shared-key=secret1
/interface wireless
set [ find default-name=wlan1 ] band=2ghz-b/g/n disabled=no frequency=2457 \
    mode=station-pseudobridge name=InternetWLAN security-profile=\
    InternetWLAN-DownUnder-repeater ssid=DownUnder
add disabled=no mac-address=6E:3B:6B:20:E9:87 master-interface=InternetWLAN \
    mode=ap-bridge name=wlan1 security-profile=\
    InternetWLAN-DownUnder-repeater ssid=DownUnder
/interface bridge port
add bridge=bridge interface=ether2
add bridge=bridge interface=ether1
add bridge=bridge1 interface=wlan1
add bridge=bridge1 interface=InternetWLAN

As you can see, I’ve setup an universal repeater. I’m testing against an Asus WLAN-base and an Mikrotik cAP. Again, it works with a notebook with W10, it doesn’t work with smartphones and Tab (Samsung / Sony).

If more information is needed please let me kow.
