I need help for wireless link R52Hn & 433AH

RouterOS Wireless Networking
1

Hello ,
Im sorry about my English . I have install one wireless link with : RB433AH , R52Hn , 2*MikroTik Dish antenna 30dBi V&H for about 14Km My routerOS version is 5rc1 I have 159mbps BW for send and 162mbps for receive and 87mbps(S)/77mbps(R) in btest ping time is ok , i dont have any time out when btest in running

——
But my problem is :
I am in SiteA
When i connect my cable from POE to switch , I can ping only the Routerbourd in siteA and the other site (siteB) is Time out .
I can connect to RB siteA with winbox and i can connect to RB (siteB) with MACtelnet in RB SiteA
Winbox show me in search box these two RB but i can`t connect to RB siteB
and when i disconnect the cable from switch and connect it to my computer every thing is OK .

———
I change first two switch in siteA and aiteB with new switch

I change the new switch with RB450 in two site

Disable RSTP on two site

Upgrade RouterOS to 5rc3 and upgrade firmware from 2.23 to 2.28 on two site

Change WDS mode to EOIP tunnel

Disable auto negotiate

Disable ethernet1 on siteB

change wireless mode in siteA and siteB (station-bridge) ( when i change Ping work about 2min then time out)

Check my connector and high voltage power near it

change my POE (24V 0.8A)

My cable is 24m cat-e-5e FTP Unicom in siteA and 52m in siteB

Now what I can do ?

What ip/subnets are you using on each unit and interface? May be a routing challenge.

3

I change my ip address , the local subnet is 10.78.91.0/24 with no route to 192.168.88.1,2/24
this is my structure
in siteA :
1:My laptop(ip address is 192.168.88.1) 2 : RB450 (Bridge all port with RSTP and ip:192.168.88.254) 3: RB433AH+R52Hn+30dBiANT IP address is 192.168.88.2
in siteB :
1: laptop (ip :192.168.88.4) 2:RB450 (Bridge all port with RSTP and ip:192.168.88.253) 3: RB433AH+R52Hn+30dBiANT IP:192.168.88.3

4

I Set all ip address on Bridge interface

5

If that is the setup you want, then you need to set the radios to WDS. On both aps:

/interface wireless
set X wds-mode=dynamic
set X wds-default-bridge=wds-bridge

The “/interface bridge” in each router should be named “wds-bridge”.

6

the first configuration on my router is :
site A :
Mode : bridge
band : 5ghz-onlyN (20)
freq(5700) superch
scanlist:5700
NV2 nstream
—

wds-mode : dynamic wds-d-b:bridge1

—
HT : any - above control - chain 0 , 1 - 0

site B :
mode: station-WDS
band 5ghz-onlyN
freq : 5700 super
scanlist: 5700
any
——
wds-mode: dyn wds-d-b: bridge1
—
HT : any-above control -chain 0,1 −0

——
then you said to me that I have to change the bridge name frome bridge1 to wds-bridge then my problem is solved.

7

The name “wds-bridge” is the suggested bridge name. It should work with “wds-default-bridge=bridge1” as long as the “/interface bridge” is named “bridge1” in each router.

8

now ,!? i have another problem … !!! some time when i connect to siteB (bridge mode) with WDS configuration , with MAC telnet on siteB routerbourd … I don`t see the (DAC)wds interface under WLAN1 interface . and when deleting the bridge interface and rebuild the bridge interface and ports (ether1&wlan1) ping is OK for about 10sec … but after 10 sec ping is time out
I check the wds … it is OK … every thing is ok but ping is time out … when i disconnect cable and connect it to my computer ping is ok
then I change the WDS configuration to EOIP tunnel

9

Maybe you should post “/ip address” from each router. It may help if I see it.
And please post “/ip route” also.

10

OK , you think my problem only about my ip configuration ?
I delete all my ip address on my routerboards … then when the poe cable connect to my computer I can ping the computer on siteB then when the POE cable connect to switch I can not ping the siteB computer

11

You should not delete the ip assignments on your bridges. You should have in the internet (ap-bridge) router:

/ip address
add address=192.168.88.1/24 interface=bridge1

in the other (station) router:

/ip address
add address=192.168.88.2/24 interface=bridge1

connection tracking will remember routes for 10 seconds. Does that time sound familiar?
If you use dhcp, insure you dhcp server does not issue 192.168.88.2.

12

Um.. and the another … this link and the same link with 6 km distance is work about 14 days with this configuration … and my problem is start today … my costumers said to me the power is turn off and turn on again and the problem is start …
all routerboard is connect to online UPS

13

If your setup was unstable, then when they requested an ip address (dhcp) on the station side of the bridge, maybe they did not get one.

ADD: And since you are redoing the setup, insure the dhcp server for the 192.168.88.0/24 net is setup on “bridge1” in the ap-bridge router. No dhcp-server on the station router.
/ip dhcp-server

14

Thank you for you help ,
Oh I don`t check for any dhcp server …
Thank you again …
Can I e-mail you my conf picture and support.rif if my problem is not solved?

15

I prefer to do things here on the forum. There may be someone else here who will see something in your setup that I don’t.
Set up the dhcp server in the ap-bridge router, then see if clients on the station side are being issued ips.
/ip dhcp-server lease

16

Thank you very much
I check this way .

17

When you set up the dhcp server on the bridge interface, insure to change the address range from
192.168.88.2-192.168.88.254
to
192.168.88.16-192.168.88.254
That will leave you ips to assign to remote equipment and bridges. Then 192.168.88.2 to 192.168.88.15 can be assigned as static.

My problem about (drop my ping ) is solved.
I change my configuration from ;
station side :
Bridge : rstp
port : ether1 , wlan1

Wireless: mode : Station-WDS , band 5GHZ-Onlyn , WDS-mode:dynamic , wds-d-b:bridge1 , wireless-protocol:any HT:any-above control , chain0 , chain1

AP Side :

bridge : rstp
Port : ether1 , wlan1
Wireless: mode : bridge , band 5GHZ-Onlyn , WDS-mode:dynamic , wds-d-b:bridge1 , wireless-protocol:NV2-nstreme HT:any-above control , chain0 , chain1

to this conf :

station side :
Bridge : rstp
port : ether1 , wlan1

Wireless: mode : Station-WDS , band 5GHZ-Onlyn , WDS-mode:DISABLE , wds-d-b:NONE , wireless-protocol:any HT:any-above control , chain0 , chain1

AP Side :

bridge : rstp
Port : ONLEether1
Wireless: mode : bridge , band 5GHZ-Onlyn , WDS-mode:dynamic , wds-d-b:bridge1 , wireless-protocol:NV2-nstreme HT:any-above control , chain0 , chain1

Now I have on Btest (Bouth S/R) 87 Mbps for send and 85Mbps on receive , with RB433AH and R52Hn , Dish antenna 30dBi
Thank you for your help.
