I have seen this kind of behavior that shows traffic in disabled port with broken switch chip. Chip was broken by over-voltage caused by thunder.

LTE interface number changes in update. I have many Baseboxes with Sierra MC7710 LTE card in remote locations. During update LTE1 interface changes to LTE2 interface. This breaks up DHCP client and firewall rules that are still trying to use LTE1 interface after update. This prevents updating remot...

Default l2mtu (about 1520 depending board) is enough to bridge standard packets with vlan headers. You don't need to create vlan interfaces, but it could be handy to create one vlan interface connected to bridge for administration if your link do not accept untagged packets. This works good if you d...

does RB260GS will have IGMP support? MikroTik product page don't mention anything about IGMP or Spanning Tree support. But if you see Atheros chip details there should be IGMP and Spanning Tree support in switch chip. http://www.qca.qualcomm.com/technology/technology.php?nav1=48&product=102 I j...

It could be some analog link too. I have seen analog wireless security cameras using 2.4 GHz in some sites. This blocks all wlan communication in channels affected.

Attachment shows analog security camera in about ch1 blocking about half of 2.4 GHz wlan channels. Then it was turned off.

What kind client do you have? I dont have that board, but others with 52n cards. I have seen bad wireless performance with old broadcom G chipsets if preamble if set both or short. With long preamble my laptops with old broadcom radios work ok. And run spectrum scan in dude. I have had problems with...

Yes, it's possible to use jQuery and any other browser based things.

You can put any static files (jquery.js in this case) into hotspot directory in router. Or allow them to be loaded from internet using walled garden.

I would say that most of adsl modems work good in bridge mode. As long as you do natting etc in good router like Mikrotik :) Many adsl modems have weak processor and low memory, so they will come a bottleneck if trying to do nat etc. in them. I have installed few cheap Tp-link adsl modems (8840T in ...

Try to re-install RouterOS using netinstall.

can you all please test the "Latvia" download mirror? What speeds to you get in your country (name it). Is it higher than ususal?

Finland, about 80 Mbps. Lightning fast compared to old mirror.

pin-status: "waiting for network personalization PIN" It is waiting some PIN code. Have you tried to disable sim-card pin using a normal phone just to be sure it is not causing problem? But I think your Sierra card could be operator locked. So it will work only with that operator card who...

I just got Sierra Wireless MC8792 card and it seems to work (tested with RB411U and ROS 5.2). Now I have to consider what antenna I will use. Do anyone have a good antenna recommendations for indoor and outdoor use? Must support 900 and 2100 MHz bands. For quick indoor test I used Mikrotik swivel an...

You have to set ipv6 address to your lan interface too. Now you have only set ipv6 address to tunnel interface. You can find your Hurricane Electric routed prefix on their site. That is the address space that you can use in your lan. They have example config for Mikrotik available too! But it do not...

That USB power reset feature is only in latest models, SXT for now I think. I have been thinking try to make some self made usb power reset implementation. Basically it should be easy by few electronic components and short usb extension cable (parts costing few euros). And by using userled as trigge...

Try with latest RouterOS versions. I noticed that something has changed to RouterOS 5.0RCs, since my 433AH now identified and formatted one sandisk card that not worked with some 4.x version when tested long time ago. But I don't see much usage for it, because it is quite slow reading and writing ca...

It's ok. Normally it is enabled like yours.

But if it is manually set to disabled then it could cause problems if not set correctly in both sides of link.

Did you try other cable? Sometimes problem could be bad or broken cable.

After that it is more and more likely faulty ethernet chip.

I have now done some testing with Nokia CS-17 usb modem, since I wanted to test some other brand than Huawei stick. Support for this Nokia stick is probably coming to ROS 5.0. Thanks to Mikrotik for adding it! (If someone interested datachannel=2 and infochannel=4) Sadly I have to report that CS-17 ...

You have to connect ethernet cable and have ethernet link up running (link led on) to blink command able to blink. Your interface print shows that ethernet is not running, so it can't blink. Are you disabled auto-negoation on ethernet interface? That could cause problems. /interface ethernet print d...

I have used 411U in car with 12 volt system, powered from cigarette lighter connector. Sometimes starting car causes such big drop in voltage that board will boot. Maybe I should get new battery to car. Otherwise I don't have had problems using it in car. What comes to 3G, I have only tested with un...

By my testing it just do not respond if there is no address to give. If client tries to renew some old address and server has some new address to give it should first send NAK response to client to tell that old address is not valid anynome. And then client should request new address and server repl...

Thanks ghiooo but those old models are not good for me. I also found those old models cheaply in ebay. In Finland we have 2100 MHz and 900 MHz 3G networks in use. 2100 MHz is used only in cities and 900 MHz in other areas. From Sierra Wireless 3G modules I would be needing quite new model that suppo...

RB411UARH

You can reset the power on the USB port aswell.

Just remembering that RB411UAHR would need external power for usb and STX is first board that implements power reset feature. Or have I missed some hw changes somewhere?

I think that good modem should not need that kind of trick to work.

mikko

Thanks for Sierra Wireless tip. I have been thinking what 3G modem to get for more serious need that I have with one oncoming project. You may have read my postings about Huawei E160E and yes, it is too unreliable for serious use. But works for me for occasional manual backup connection in my home o...

Have you tried to look what amount of traffic and connections are going when connection slows down? That would get some clue what is happening. Since your hotspot is working some time I suspect that problem is not in it. If you are using some non-symmetrical (asdl for example) connection it could be...

There is no way to power rb from usb port. Usb port is giving 5V and max 500mA so about 2,5 watts. RB433 require minimum 10 volts and 4 watts without wireless cards and much more watts with wireless cards. So even making some dc to dc converter, usb would not supply enough power. You can get 12V fro...

Just tried with static only addresses and windows xp gets address without problems. And don't get address if there is no entry in leases table. I see that it is working as it should. I am using RB750G and 5.0RC11. Windows XP was home edition with SP3.

Seems that MAC Server documented default value all is disabled by default in 5.0RC11 and only some interfaces are enabled. I tested with RB750G. But you can change what interfaces mac server listenes. http://wiki.mikrotik.com/wiki/MAC_access Or this could be undocumented default security enhancement...

I have had similar connection problems with a Huawei E160E usb modem. But it has done the same with windows too, so I think that is not necessarily only routeros issue. I recommend to check if there are firmware updates to your modem. My e160e has worked much better after I updated modem firmware to...

I tried netinstall 4.17 holding the reset button and releasing. It never popped up. I tried the same with winbox. Nothing. thanks for your attempt.
