Good day everyone, I'm racking my brain trying to figure this out and hoping I can get some help or clarity here, I've tried searching here and haven't found the solution. So here's the setup we some access points connected to a UBNT edgeswitch with a couple of VLANs (1,100), Edgeswitch connected to...

If your goal is just "switch over when one link is down" and the situation is as simple as this, you can just put in 2 static routes with different distance and with nexthop checking. Of course you can use BGP but it is more suited for situations where there are multiple paths amongst 3 o...

Hey everyone, so I have two sites that are currently connected via a PTP link using static routes. I am adding a second PTP link which gives me more bandwidth but I would like to keep the old link as a backup. I would like for them to switch back and forth if the New link goes down and when it comes...

I did a couple of searches on this topic and didn't seem to find anything so here it goes. I am running several ccr routers over several sites (WISP) that hand out DHCP at each site. Most clients don't go outside the norm of plugging our equipment into their routers and only pulling 1 ip address fro...

So what happens to the ubnt client is basically either static electricity build up or a power spike blowing out the LAN port on the radio. Sometimes that's all that happens and we have to replace the radio, but other times it will kind of create a loopback almost where the radio will create a duplic...

I've been racking my brain on this one, here's what I have. I have UBNT clients connecting to UBNT AP's connected to MT Switches and at certain sites those switches connected to Cisco routers (for the time being, they will be swapped out with CCR by end of the year). Now UBNT has this weird glitch t...

It depends on your network, and there's not enough information there for anyone to be able to tell you for sure. You can assign as many subnets and IPs to a routed interface as you want however. The only reason to use a bridge is if you wanted those subnets across multiple layer2 interfaces. well I...

I am making a change from a Cisco 7507 to one of the Cloud core routers. Think I have everything pretty much setup correctly but I wanted to double check on this one thing. On my 7507 the local interface has 3 addresses assigned to it, 2 Public and 1 10.x.x.x address. Now would I add all those to th...

Well shortly after my last post it went down again, decided to get a climber up there to swap the RB2011 out, since then I have yet to have any problems. Knock on wood, I think something was just not working properly with that RB2011 that went up the first time, we'll see.

mherbst01

Ok so it happened again, this time I connected to an AP that reported it was up, I was able to pull an IP address and get online, went to several websites without a problem. When I gave myself an IP address that is whitelisted to connect to my switch I was unable to connect to it. However, when I co...

I have to correct myself from earlier this morning, the AP's plugged into ports 4 & 5 were reporting up and I was even able to communicate with them and customers connected to those AP's. All AP's and devices plugged into ports 6-10 were I was not able to communicate through the switch even thou...

mherbst01

Not sure if I have this in the right section but here it goes. I recently installed an RB2011LS at one of our tower sites, not the first time we've done this, but I've been having all sorts of issues since we've installed it. Last two nights I've had to go out onsite in the middle of the night to ge...

When using a switch chip it completely bypasses the CPU for traffic between the ports, and therefore it never touches the firewall. The router has no way to block that. The closest you will likely get to what you want to do is to create a bridge and bridge all of the ports together. This will then ...

mherbst01

Correct. Just set ports 3-9 to master-port of ether2 and ports 2-9 will be switch together. Well I got the 493G in and have found out that you can't have 2-9 switch together, you create two switch groups. Within that it hasn't solved my issue, I created a firewall rule to drop upd 67-68 from source...

mherbst01

The 493G would probably be the closest. It has 9 ports (1 more than the GS108T) and is also gigabit.

And I would just have it run in switch mode and not in router mode then?

mherbst01

Hey guys, looking for some advice on what I should go with. I am using a Netgear GS108T but recently I can't login to the Switch and its unreachable via ping. I have 4 UBNT Airmax sectors hooked up to it, I am looking to replace the GS108T with a Mikrotik so I can do some firewall to block customers...

mherbst01

if you can change them all, then exchange them. do not know why these cards have poor quality filters, because this problem only I've seen in these models . I never got to thank you for your help on this issue, out of the 11RBs on the network we've had to replace 4 since you recommended this soluti...

mherbst01

I was just pulling customers off that sector on to other ones when I saw your response, looked at the old unit that came down and sure enough they were expanded and one looked to have had a leak. Thank you so much for the info, I am going to order some and replace these, see if it does the trick. Th...

mherbst01

I've pretty much come to my rope's end on this one guys, I've already ordered a Ubiquiti sector to put up instead. I have 9 customers on there that can't get consistent internet so I have to make a change, thank you for the suggestions though guys.

mherbst01

I was just checking the RB using the dude and saw its cpu was at 27%, seemed a little high for what is now only 9 customers. I was wondering could that be causing the problem, getting "overloaded", if so how would I be able to solve that? check the "tool profiler" menu to see wh...

mherbst01

What about wireless card config? Are you using high tx-power? If yes try to set it to 17 or default.

Yea it is set to default and I guess I spoke too soon about it never giving me a problem during the day because its rebooted 5 times since I logged in at 9:54am.

mherbst01

Ok so I was up late last night so I decided to watch the sector see what it was doing, I would be logged in and I would lose connection, after it came back up the uptime had reset like it had rebooted, in the logs however it just says interface info: ether1 link up (speed100M, full duplex). Didn't s...

mherbst01

Hi, I would enable some of the logging options and also save them using to disk option and not echo. That way you don't lose all the info on reboot and you could maybe see what is happening before the unit actually 'reboots'. Rgds, Mark. Ok I set them all to disk, hopefully this gives me some more ...

mherbst01

Get a 24v POE. You are probably losing too much voltage over that long of a run. XR5 is a power hungry card. I ran into similar issues with the SR9 and 133C combo. One side ran fine 90% of the time, the other (my side, luckily), had some quirks. Bottom line, if you run any high powered UBNT cards, ...

mherbst01

Well it did it again this morning, came in and it has an uptime of 1:40:22.. so it "lost power" about 7:50am, I checked every device on that tower that are plugged into that UPS and surge protector, none of those devices lost power. Guys I am really pulling whatever hair I have left out, I...

mherbst01

Hi, What you might need a higher power PoE unit as in delivering Amps. This is where the power draw is. If your RB and the XR cards have high usage, then you are going to draw a bit more power than is normal. What are your 18vdc units rated at? Rgds, Mark. 18v 1amp.. I took some customers off that ...

mherbst01

Hi, When you say 'switched out PoE' did you replace with an identical one? It might be a good idea to change one with different voltage/power and see what happens then (don't go over 24vdc). Rgds, Mark. Yes we did swap PoE with an identical brand new out of the box PoE, it had been working for a ye...

mherbst01

I disabled it last night but when I came in this morning it had lost power and rebooted about 1.5hrs ago. The good thing is that it seems to be "losing power" not proper shutdown and coming back up, previously we would lose it for hours then it would come back and have that error. Now its ...

mherbst01

First, check the watchdog timer and disable it.

I've never enabled that, so if its a default setting it is set on all my routerboards, yet this is the only one that has been giving me this issue. I'll give it a try though.

mherbst01

I have an RB433 + XR5 that has been losing power just about every night, goes down and comes back up after a couple of hours. We tried switching out PoE, moving it to a different port on the switch, tried a new patch cable. That still didn't work, it did it the next day, well yesterday we changed th...

mherbst01

Did you change any RouterOS configuration before reboots started?

No none, hadn't messed with that radio in quite a while, just kept working. Haven't had any rain or anything, being we're in Texas, just seems really really odd to me that it does this at night and not during the day.

mherbst01

I have an RB433 that really hasn't given me any problems since the day I installed it about 1-2years ago. Over the last couple of nights its just going up and down up and down, basically rebooting, I monitor it with The Dude and have notifications sending me texts when its up and down, I got 65 text...

mherbst01

Thanks for your response Brad, I don't have Periodic Calibration enabled on any of my sectors, as far as the noise floor threshold, that won't really stop it from going below that will it? I'm really looking for something automatic that if the noise floor drops below say -90 it either sends me an al...

mherbst01

First the background.. RB433ah XR5 Occasionally I have this sector's noise floor go from -94 to -83 or lower, when it does that it drops customers from the normal 21 to maybe 13 or so. When I see this I will disable the sector and enable it after 3 seconds and it will fix it. I use the dude to monit...

mherbst01

Whenever I have my tower climbers work on these radios up in the air (rb433ah + XR5's) If we need to swap the radios out I always shut the board down. Can these things be hot swapped? Say if I just disable the one they need to work on, they swap it out and then I enable it once they insert the new r...

mherbst01

I just recently revisted this issue, I am trying to set my Cisco switch to 100/full for the port going to the RB800, the RB800 is set 100/full as well auto negotiate off. The port however on the switch reads 100/half, so I set the port on the switch to 100/full and it drops connectivity to the rb800...

mherbst01

So it happened again this morning, I have a script that runs on my 300 sector that disables at 6am then enables 3 seconds later, it did that correctly then 12 mins later dropped everyone. I got up at about 7 and saw this immediately disabled and enabled and everyone came back up, didn't see what the...

mherbst01

Do you have wireless logging turned on? (System/Logging) Some 600 boards in the past have had reboot problems for various problems, including firmware (not RouterOS) rev level. This is addressed in many other threads. Just read the log and see if you have a red watchdog reboot message in it. Or, wh...

mherbst01

Take a 411 and a new XR5 in it and connect the sector antenna to it. If this makes a difference, too many cards in the same band in a 433. If you have 2-XR cards, it is possible that could happen, but your scenario looks a little different. I have had this 'rising and lowering' noise floor issue at...

mherbst01

I noticed this weekend on one radio that had dropped clients the noise floor was down to -83, I disabled and enabled the radio and it jumped up to -95. Also saw another radio down at about the same maybe even lower -80, it wasn't dropping anyone but ccq's were extremely low which normally they aren'...

mherbst01

Just can't seem to figure this one out everybody.. I changed frequencies on this radio and it dropped on me today, didn't notice though until about 30mins after the event(our dude server is overloaded).. I'm looking at it now and client tx/rx ccq's are good everyone is consistently 75/75 or better, ...

mherbst01

Here's what gets me, its only affecting one area, off this tower we have about 100 or so people in one area, so we've stacked a few AP's to focus on that area. 3 radios on 3 different boards all broadcasting 20-40mhz apart in frequency and it's only affecting those 3 radios. Friday night it was hor...

Sector antenna is a Vertical polarization and all clients are set to Vertical.

mherbst01

I've been fighting with this thing all night, couldn't enjoy a night out with friends because I kept logging in and checking sure enough I had to disable and enable the sector several times tonight. Well finally I am home and monitoring the sector, It dropped, went from 30 clients connected to 3. I ...

mherbst01

I'm using RB433ah + XR5 with clients using NS5's, PS5 to connect. Over the last couple of days out of nowhere clients connected to a sector all drop off, as a matter of fact it just happened a few mins ago. The radio is still enabled but nobody connected to it, when a few mins. ago it had 20-30 unit...

mherbst01

I set the device to 100/full and had it ping a device on the same switch 10000 times, dropped 2 packets. So it seems to have solved the issue, thank you everyone for your help.

mherbst01

Try disable auto negotiation on RB800 and set speed to 100Mbit. What cable length you use? PoE cable length is probably 60ft max, jumper to switch 7ft, I tired taking it off auto negotiate and getting about 3% packet loss, gonna keep a ping going all day just to make sure it works. Before it would ...

mherbst01

I just put up an RB800 + XR5, I've been noticing its dropping its ethernet link, Its being powered by pacwireles 48v PoE, its connected to a Cisco2950G. I have 3 other boards 433AH on that same switch and none are dropping, has anyone else seen this happen before? I did a /system routerboard setting...

mherbst01

I put that in and I haven't seen it take affect.. it claims its run but it doesn't appear to have run. Do I need to put something under /system scripts also?

mherbst01

Thank you very much, just put it in for tomorrow... Thanks again

mherbst01

I've never done a script and I use winbox to configure and monitor my RB's.. I would like a script that would run every morning and just disable and enable one of my wlan. Is this possible and would anyone please help me in accomplishing this?

mherbst01

I am using an RB433AH with two XR5's, I did do a /system health and it was at 22.1 V, of course this was after it had happened, and if I look now its at 22.3. I have about 51 NS5's connected to these XR5's, 31 on one radio and 20 on the other. just as I was finishing this post I looked again and the...

mherbst01

So I upgraded to 4.2 over the weekend on Saturday night actually, really thought that solved it but today just before lunch I noticed it did it once again. I think this weekend I might just have the PoE injector swapped out, see if that's it, I did just email support thought with the supout file.

mherbst01

my rb's are being powered via 24volt PoE, each RB has its own PoE, cables Ethernet isn't longer than 25ft. What i meant by same source is they are plugged into same surge protector.

mherbst01

So this week my routerboard has been working fine but out of nowhere it drops from the network, i can connect to it from the radio side and I'll just reboot it and it comes back up. Then I get swamped with other things and forget all about it, well it happened just a few mins ago, logged in, looked ...

mherbst01

well as of late the problem hasn't been the bottleneck, its been uploads are very slow. Customers are hitting their down speeds but I got an email from a customer today saying he was only getting 50k when he's paying for 1024k UP. I've messed with rts/cts turned them both ON, 433ah+xr5 and the NS5's...

mherbst01

ok so i uploaded the wireless test package and i think It seems to have improved, I've got download up to 14mbps overall and no one seems to lag. My issue lately though has been upload, i'll run a speedtest pull 6-8mbps and my upload will be 1-2mbps where it use to be more or less on par with the do...

mherbst01

bump...

Medianet mentioned that 7-8mbps is where things would bottleneck for him as well, has anyone else seen this and been able to resolve this as well. I would hate to have to put up more sectors because we can only use 8mbps of traffic per sector, anyone got suggestions?
