I am begining to sound like a broken record here on the forums - so please excuse my tone if it is not agreeable....

Why are your bridging your WLAN and Ethernet ports together? You do realize that once bridged that ALL packets from ALL interfaces get sent out TO all interfaces - right? So the way you have it now you have at least doubled your network traffic.

You should be able to do everything you need via routing. You can use either static routing or OSPF (BGP and RIP are also workable but OSPF is easier..). Worse case if you need to make data be in the same networks as something on the ethernet side you could use WDS and/or IPIP or EoIP tunnels.

Do a little more reading on the wiki and/or MT ROS manuals and you'll see what I mean....

I can back him up. He convinced me to avoid bridging for my backbone, and it worked out much better.

I have one virtual AP WDS bridge right now to connect family to my internal network and it is a bandwidth hog. Once I get a few more people on, it'll probably have to go.

Same here, Routing is the way to go. Never been faster/cleaner/happyer customers. thanks Thom

Routing is always the winner in any comparison with bridging here !!!
as I read here its because when bridging , the packets come from one node goes to all nodes ..
I really want to know if this is not hapenning in routing , and what do you mean by bridging ? bridging what ? eth+wlan ?
bridging in the main AP or in all AP's in the network ?
i have this scenario , what do you suggest please ?

Main ROS --- Main AP (RB333) ====== client ( RBxxx ) -----client ROS ---- client network

1- Main ROS : Wan - NAT - Lan .... xx.xx.xx.xx , 192.168.1.1
2- Main AP : eth1 + wlan1 = bridge1 .... 192.168.1.2
3- client RBxxx : eth1 + wlan1 = bridge1 ..... 192.168.1.3
4- client ROS : Wan - NAT - Lan ..... 192.168.1.4 , 192.168.2.1

Hi,

Can u send me an example. I also use bridging between eth and wlans and I would like to use ospf. I use the following: linux router ---[Mkt(eth+wlan1+wlan2)]----cpes(rtl8186). I read from wiki but it did not work.. I would appreciate your answers, meanwhile I get an answer I will be trying to solve it.



best regards,

Sure would be nice for everyone to know how you fixed your issues - that's the purpose of the forum - to share knowledge...

You are already using 192.168.2.x for your client. I prefer to use 10.x.x.x for 'distribution' networks - you can use whatever private addressing scheme you want the info here would still be valid - just change the IP networks to what you want.

1 - Main: WAN - NAT - LAN.... xx.xx.xx.xx, 192.168.1.1 (netmask?) /24?
Add a NAT rule to NAT Client IPs - currently you have 192.168.2.X/?
Add a NAT rule to NAT 10.0.0.0/23 (going to use this for your distribution)
Add a routing rule - src 0.0.0.0/0 dst 0.0.0.0/0 action=lookup table=main
Add default route dst 0.0.0.0/0 gw=xx.xx.xx.xx (WAN)
Add route 192.168.2.x gw= 192.168.1.2 (to Main AP)
Add a route 10.0.0.0/23 gw=192.168.1.2 (to Main AP)

2 - Main AP: LAN ...192.168.1.2 WLAN...10.0.0.1/24
Add a routing rule - src 0.0.0.0/0 dst 0.0.0.0/0 action=lookup table=main
Add a route 192.168.2.x/? gw=10.0.0.2 (to Client RB)
Add a route 10.1.1.0/24 gw=10.0.0.2 (to Client RB)
Add default route dst 0.0.0.0/0 gw=192.168.1.1 (To MAIN)

3 - Client RB: WLAN...10.0.0.2/24 LAN...10.1.1.1/24
Add a routing rule - src 0.0.0.0/0 dst 0.0.0.0/0 action=lookup table=main
Add a route 192.168.2.x/? gw=10.1.1.2 (to Client ROS)
Add default route 0.0.0.0/0 gw=10.0.0.1 (to Main AP)

4 - Client ROS WAN...10.1.1.2/24 LAN...192.168.2.1/?
Add a routing rule - src 0.0.0.0/0 dst 0.0.0.0/0 action=lookup table=main
Add default route 0.0.0.0/0 gw=10.1.1.1 (to Client RB)

That should do it........ Of course you have to take everything out of the bridge.... The easiest way to do this is assign the addressing scheme you want to use to the interfaces indicated, but assign them TO the interfaces, not the bridges. Add the routes, NATs and Route Rules. Then - starting at the client ROS, disable the bridges one at a time. Now it make take a few minutes to get the units back after you take them out of bridge mode.....so wait for each unit to come back in turn before proceeding to the next unit. That way if you mis-type something you should be able to get back in via MAC telnet and fix it from the unit 'before' the one that you disabled the bridge on.

razvan_fzl - Too many variables to do OSPF here on the forum...the Wiki has the right info - just watch the version you are using, and be warned that some of the 3.x versions do not work well....

for us it was enough to keep the signals at -85(max) , so we had to take over the 5 client that were over that limit and the problem was solved ,

Wow scary to run customers anywhere near that signal...

Wow scary to run customers anywhere near that signal...

I have one with that high of signal (PISSING) me off he is 700 feet from it. Clients that are a mile away from it have a 75 signal..... I dont know what it is im thinking interference with a client.... Goign to have to Line it in the best i can. all the others are in the 70 lows and Highs depending on weather/.. -Jordan

Could be in the shadow if the tower doesn't have enough downtilt.

Could be in the shadow if the tower doesn't have enough downtilt.

im guessing that would be correct John, 15 DBI antenna, Yea i know smaller Dbi.... but it is what i had. I will do my best to make it work for now..... I will have to put a 12 dbi or 10 dbi on the tower. However the tower is only 50 feet high.. anywho -Jordan

Even a 15dbi antenna should have plenty of downwards coverage for someone 700 feet away if it's only 50' up. What kind of CPE/antenna?

airbridge, cpe unit. 100 mw 15 dbi directional antenna, Tree tops in the way but very little. -Jordan

What is your signal strength at each end?

R/

signal ON AP end is anyweres from 79-89 usually around 80-86

CPE end runs an Rssi of 80-85 Percent, and signal quality of 90 % -Jordan

Hi Jordan....

I would say there is your problem - the -80 to -86 signal level.... Once you get in to the -80 territory things can get interesting.... Is it possible for you to set the client end for say 802.11b only and/or set the TX/RX (on the client end) for 1, 2, and /or 5.5mbps (.11b standards) only, this may bring their signal level up to a more acceptable level....which would cure your issue (until the trees get in the way more....)

Yea, i will have to relocate the antenna or re-aim in better, The way it is right now i am restrcited to a degree on how far i can move it. All my other CPE units run in the 70-78 range. when i run out of these units im going to go with mikrotik gear, and much higher DBI antenna or yagi's to focus the signal in. 21-28 dbi with good wireless cards in it. -Jordan

hi!..
i'm using RB532 with XR2 ptmp to my end-user client..

i'm having trouble when the traffic >200kbps, ping rate to all my client increasing highly (3 digit)..
but when the traffic is <200 kbps, ping rate at 1 digit..

i am using POE with 48V, 0,4A..

does if i change to 18V 3A will help much?


i used to have R52 on this board, and it doesnt problem at all..

ponywaterhouse -

Changing the PoE won't make any difference with only one XR2 in an RB532.

More than likely you have a 'bad actor' - one of your clients has low power to/from your PtMP link. Something like less than -80db. When you have a client like that it can cause issues for everyone on the link.

The difference between (receiver) the R52 and the XR2 is that the R52 has a more sensitive RX function than the XR2. So the lower power from the one client does not impact the entire link as bad. Pretty much if I have a client that comes in at -78db or less I try and put a WPOP closer to them or I don't service them until I can. Saves me a lot of trouble...

When I say less than -80db it means the number portion is higher like; -82db, -85db etc... these are less than (power now) than -80db.

What kind of CPE's are on your clients end? Whats the signal strengths on these links? What is your noise floor? is this LOS? Or NLOS? how far away are they from the AP? all these questions will help us solve your issue. -Jordan

Hi..

on my all client, i use JAHT4001BR..
i suppose all of the link is LOS.. (the one i installed on client is LOS, but i don't know whether it si LOS or nor if my client installed it themself)

the noise floor on my XR2 is -95
and the signal strength is variance beetween -65 to -85 (depends on location)

bandwith per client is only 128 kbs (burst 256 kbps), so i didn't use mikrotik RB for my client..
in other side, it still to expensive for me & my client..

if the problem is on XR2 card, are there any recomended minipci (with high power)?

thanks for the respond guys..
