We were attempting to use a RB44gv for one of our core routers in a server, but ran into similar problems found in other threads. I have looked over the list http://wiki.mikrotik.com/wiki/Supported_Hardware#Ethernet_chipsets but wanted to see if anyone had any recommendations for decently priced gig...

We have recently updated the passwords on our Dude install. However, when I type the new password into The Dude when opening it up, it still is remembering the old password. How can I reset this so that it will save the new password with the "remember password" box checked? Where is this i...

We have tried that in the past, and we also just tried that with the situation that is ongoing on our network. Any other suggestions?

There appears to be a bug in the latest version of the Hotspot code. We are running multiple Hotspots on 3.0. We are also running numerous other hotspots on 3.11 - 3.30. The problem is with communicating with devices behind the Hotspot that are bypassed with either the Walled Garden IP list or with ...

I was trying to add an RDP probe today by adding a new TCP probe and setting the port to 3389 and checking the "Connect Only" check box.

This does not work.

I think the "Connect Only" option on probes is just broken in The Dude 3.4.

Can anyone confirm this?

cramerit

Thanks for the reply. I've sent over an email to support with all of the information I could find.

There is definitely a consistent repeatable situation here with the dude.exe client.

cramerit

I am getting an application hang on dude.exe 3.3 on two different computers. One is within Parallels (latest version) running on a Mac. The other is on the Dude Server itself when accessed through Windows Remote Desktop. The client actually does run for a while but eventually hangs and crashes. On s...

cramerit

We recently upgraded from Dude 2.2 to version 3.1. Ever since then the client has been intermittently freezing or hanging and crashing. This happens on several different computers and even when remote desktopping into the server. Sometimes the client will start functioning again and other times it w...

cramerit

Thanks for your reply sergejs. We run a number of hotspots and see them partially crash at various times. The crashes are not always catastrophic and it usually seems that some portion of the firewall or proxy stops functioning. With all of the hotspots that we run, I can't find a common condition f...

Tanker:
Can you tell me what enclosure you used in this photo: http://s279.photobucket.com/albums/kk12 ... LEANUP.jpg

Does anyone know where I can order this enclosure?

It looks great.

cramerit

Just chiming in and confirming that I am seeing the exact same problems. We attempted to upgrade a working 2.9.51 hotspot to 3.10 and 3.11 and we saw the same problems with a crash. We had about 200+ users going all at once, so we saw the deterioration happen very rapidly (about 1 minute) as was des...

cramerit

What about the "HTTP Proxy" setting in the Server Profiles where you can specify an external proxy server to use?

If we did set up an external proxy server and configured hotspot to use it, would this completely bypass the internal proxy server?

cramerit

I tried the SBE DS3 PCI card in 3.x and it does not seem to work. The card shows up in ROS, but is disabled after every reboot and doesn't seem to function after you enable it.

This card has been discontinued and is no longer available through the manufacturer.

It works fine in 2.9.x.

I remember turning on Transparent Proxy on the default user profile sometime during our testing, but the majority of testing was done with Transparent Proxy on. What is the recommended configuration for this scenario? Is there some specific configuration involving Transparent Proxy on the default us...

Update: After downgrading from 3.11 to 3.10 the problem persisted. We just downgraded from 3.10 to 2.9.51 and now the redirect through the Walled Garden is working again. It appears that there is definitely a problem with 3.x hotspot and redirecting through walled garden. We suspect that it is based...

cramerit

Thanks for your reply. I actually saw that post earlier as we were trying to troubleshoot this and tried it. Things didn't seem to change at all and we were still having the problems.

Any other ideas? Is there a real issue with ROS 3.x hotspot that has not yet been resolved?

cramerit

We are also experiencing this problem. We're trying everything mentioned here and nothing seems to be working. Walled Garden addresses in Hotspot on 3.x are not working.

Has anyone tried using an external proxy server?

cramerit

We are having a similar problem. We just upgraded our 2.9.49 hotspot to 3.11 and are receiving some strange behavior. This system had been working for a couple years prior, then after upgrading it to 3.11, attempting to access our hotspot homepage through the walled garden results in half loaded web...

I wanted to recount a recent situation that we put a lot of time into. I hope this helps some other folks out along the way. We recently put MT gear up on a 300' tower. We had the following setup: * PtP Backhaul with RB333 / XR5 / 28dbi Solid Dish w/ Radome * 5 GHz AP with RB333 / XR5 / 90 deg 5 GHz...

cramerit

Just getting back to you on this matter. I thought that they were clicking the connect button too, because when you click the connect button, it does change the mode to station and sets the SSID. However, there is really an issue here with the mode being reset from Station-WDS to "Station"...

cramerit

We're still seeing this. We set the client to "Station-WDS" mode or "Station-Pseudobridge" Mode and it will immediately switch itself to "Station" mode before attempting to connect.

Anyone else seeing this?

cramerit

Ok, we are seeing this same issue with all Mikrotik Gear. We've recently been putting up installations using an assortment of MT Access Points (RB 532 and RB 333) and an assortment of radio cards (8602S, SR5, CM9). The clients are also mainly RB 411s and some RB 133s. We've been trying to run exclus...

cramerit

I can confirm that we have seen this same exact issue with several RB411 boards. It doesn't happen all the time and we have not seen it with any other boards other than the RB411. We can not reliably reproduce it - it seems to happen intermittently. The general scenario is: 1. Se up the client in St...

cramerit

Just to let you know, we tried the NSTREME suggestion with framer-policy=best fit and framer-limit=4000. This did not change the problem. We also tried RC13 and we're still seeing the same results. Extremely easy for us to reproduce: simply put up a PtP with RB333 and RC9 through 13. Choose any wire...

With RB333 ptp link (RC9 and RC11), we've seen good wireless connectivity until we we load the link with actual traffic from lots of users. When the link is loaded, the wireless connection then bounces often and immediately reconnects. We had this same problem with RC9 on RB532. After rolling back t...

We are running a mikrotik hotspot in a location with many users. They are set to authenticate to a freeradius server, which has been up and running fine for some time now. Recently, we have had two specific problems with users not being able to log in on this specific hotspot router (we have others ...

cramerit

We are having very similar problems running hotspot. It seems to affect things going through IP Binding bypass. When we add IP addresses into the IP Binding Bypass list on hotspot, they will not get access to some websites. The TCP MSS rules don't help in this case.

Any word on this?

cramerit

We are currently using an SBE T3 PCI card in our Mikrotik Router to pull in a partial rate DS-3 service.

Does anyone have any more of these that they would be willing to sell? I would like to pick up a spare and have one or more available for additional feeds coming in.

cramerit

In response to the closed topic: http://forum.mikrotik.com/viewtopic.php?f=7&t=15647&st=0&sk=t&sd=a I would like to post the following solution / explanation for the problem that has been discussed at length. After wrestling with this issue for over a year and reading every post I co...

cramerit

We have this problem on several sectors.

We have added static ARP entries for the offending clients and this solves the problem.

We do not have an explanation for why this occurs in some situations and not others.

cramerit

FYI:
The problem here ended up being that we put one of the 5.8 units into NStream mode. This caused the problem. When we disabled NStream on the one unit (so neither unit is running NStream) the performance went back to normal.

cramerit

We are seeing the same problem here.

cramerit

We did try cloning the MAC on our AP, but they still would not associate.

Any other ideas?

cramerit

We just tried this again for the second time and it DID NOT work. We had an MT box with a Prism radio in it and about 20 clients connected. The clients are a mix of MT CPEs connected in station mode and Tranzeo CPEs. We cloned the settings on the original AP and then replaced it with a new one and a...

cramerit

I suppose we could try, but I have another 5.8 link that is the same distance (7.5 mi) running right next to it and the throughput on that is 10 Mbps no problem. Mikrotik Support suggested trying Dynamic Framing Policy in NStreme, but I have no idea if that will do anything. I have to bounce this li...

cramerit

Yes, the ack timeout is set to dynamic.

What else should I check?

cramerit

I have one 5.8 Sector with 5 clients on it. 4 of the clients are fairly close in (< 0.5 miles). One of the clients is far away (~ 7.5 miles). All of the clients have great signal strength and very low noise. Signal strength is around greater than -72 for all of them and noise is -102 throughout. We ...

cramerit

Maybe I could rephrase my question. Is there a way to mark a packet by the URL address in the HTTP header?

For instance: with http traffic coming in on port 80 to ptr.domainname.tld, can I mangle mark the packet with "packet mark"?

cramerit

do you know if RouterOS affords the ability to filter / direct traffic based on the incoming URL of the traffic?

For instance
http://www.yourdomain.com DST NAT --> 10.0.0.1
http://www.yourdomain2.com DST NAT --> 10.0.0.2

Any help is greatly appreciated.

The Dude Windows client is great. The Dude Web access is also great. But how many applications and web sites do you want to have to go to? I don't know about you, but I've got plenty. If we can publish network information via RSS, then there is no limit to where we can have network status informatio...

cramerit

This makes no sense. http://www.cdw3.com/SR9_Shot.jpg See the reported noise floor? And the connected signal strength? I get great ping times and can push though 2+ Mbps both ways. I'm not complaining, but I just spent several weeks trying to get it to work on channel 2437 with a noise floor of -78...

Any chance we can get RSS feeds added to this thing?

Enabling connection tracking does seem to do the trick.

Thanks for your help!

cramerit

So are you saying that enabling connection tracking may help this issue?

cramerit

do you have any ipsec policies on the box? I just learned ipsec policies can modify packets even if peers aren't configured / connected. Don't fragment bit can be cleared or set - although I can't make it work, maybe it's part of it. We're not using any ipsec on any of our boxes, but if we could us...

I had some trouble last night with an EoIP tunnel that was established over a wireless link. This tunnel had been working well for some time (months), but after a reboot of Router B (see below) the EoIP tunnel would no longer pass packets greater than 1458bytes in size. Any packets 1458 bytes or les...

cramerit

This happens to us but only if the server loses power. On a normal reboot, it will keep settings, but if power is lost, Dude comes back up with no settings.

cramerit

Is it possible to use the hotspot function and still apply some kind of global traffic shaping all in one router? It seems like the hotspot function uses up the Mangle flow mark and makes any other kind of QoS difficult to do.

Can this be done with 2.9?

cramerit

I believe you would just enable proxy-arp on one of your interfaces to make this work.
