I have almost finished configuring our RB2011UiAS for 2 WAN PCC load balancing and NAT hair-pinning. The last thing I have done is enable the DHCP server and disable the DHCP server on the previous router we were using. All of the devices on our LAN have been able to connect except one, a Macbook Pro running 10.9.5. This machine gets an IP from the server, but it can't connect to the internet. The logs in the RB2011 show the following:
17:52:59 dhcp,info DHCP assigned 10.0.2.82 to 90:FD:61:EC:D5:BE
17:55:28 dhcp,info DHCP deassigned 10.0.2.82 from 90:FD:61:EC:D5:BE
The first line is when I connected, and the last line I think is when I disconnected. However during the time I was connected I did not have an internet connection and I could not ping the RB2011 from a terminal.
I see some people have had similar issues here: http://forum.mikrotik.com/viewtopic.php?t=96472
I tried changing the Authoritative setting to "yes" but this did not change anything. The access point is an Airport Extreme Base station, and as far as I can tell TKIP is not enabled.
What could the problem be here? How can I get this Macbook Pro online?
Re: 1 computer on LAN can't connect to router/internet
So I have changed the Macbook Pro to have a static IP that connects to the old router on the same subnet. This works fine, but when I change it back to DHCP it gets an IP from the RB2011 but there is no connection to the internet.
I could really do with getting this device online - does anyone have any ideas what it could be?

Re: 1 computer on LAN can't connect to router/internet
I just tried to connect via ethernet cable to our switch and the Macbook Pro has the same problem, so it's nothing to do with our Access Point.
I then just tried logging in to the router and removing the DHCP lease assigned to the computer. The computer now has an internet connection! However, it still has the same IP address as before (10.0.2.82) but this is not reported in the DHCP lease table, so I am cautious as to whether this is actually fixed or not.

Re: 1 computer on LAN can't connect to router/internet
The issue has returned unfortunately. The same Macbook Pro which couldn't connect before had been working fine until this morning. Once again I removed the DHCP lease via the Webfig interface and it was back online, again with the same IP address. I really need to fix this, as I am not always around to remove the DHCP lease, and obviously I shouldn't have to.
Can anyone help with this?

Re: 1 computer on LAN can't connect to router/internet
Can you ping gateway ( Mikrotik's LAN interface) from that MacBook while internet is not working?
Is " Add arp for leases" enabled?
Whats your lease time? According to log, address was used for 2min 29s.

Re: 1 computer on LAN can't connect to router/internet
I think some Apple products may have some option for "DHCP security" or whatever.
I switched a DHCP/NAT network to a MikroTik router today and I have seen the same thing: there is one computer
that refuses to accept the lease from the MikroTIk, which has the same IP as the previous router.
I think the computer stores identity information about the DHCP server (like its MAC address or unique ID) and
detects that this has changed, and presumably it detects this as an attempt to spoof.
I have no idea if this is really true and if this is an option somewhere. Hundreds of other systems just migrated
without effort (asking for their previous IP address and getting that assigned from the MikroTik), only one is failing.
It looks like it just ignores the offer. I see it making a DHCP request, it gets a DHCP offer, and then nothing.
After 10 seconds the MikroTik removes the entry from the visible leases table, but of course the MAC/IP pair is
remembered and the next time the device tries it, the same IP is offered and ignored. Strange, but could be the above.

Re: 1 computer on LAN can't connect to router/internet
I had a similar issue a number of years ago with some mac devices. I found a solution was to copy the mac address and put it in the DHCP client id option under dhcp and the apple device would get an IP instantly. may be worth a try.
Re: 1 computer on LAN can't connect to router/internet
In the Mac? Or is this a change you made in the router?I had a similar issue a number of years ago with some mac devices. I found a solution was to copy the mac address and put it in the DHCP client id option under dhcp and the apple device would get an IP instantly. may be worth a try.
Re: 1 computer on LAN can't connect to router/internet
On apple devices if you open the network settings and go to dhcp option you will find the setting.
Re: 1 computer on LAN can't connect to router/internet
Ok that is a bit unpractical here, it is a "guest network" that visitors use to access internet while in te office.
I expect that the problem will go away by itself when the leasetime that was offered by the previous router has
expired.

Re: 1 computer on LAN can't connect to router/internet
It seems there are issues with other computers on the network too. Lots of them (mostly Mac's) can't ping the router's IP, although they receive an IP address. Also a PC on the network can't access the internet. This machine has trouble with DNS servers. I am using Google's servers (8.8.8.8 and 8.8.4.4.)
Perhaps there is something wrong with my config, although it was working for a few days last week without issue. I have posted it below.

Re: 1 computer on LAN can't connect to router/internet
Did you try the above solution posted by dgnevans?
Re: 1 computer on LAN can't connect to router/internet
Yes I tried entering the MAC address of the client computer but it didn't work. Also, I can't realistically expect guests to know how to do this.
Re: 1 computer on LAN can't connect to router/internet
is it possible to setup a computer on your network or another devices as a temporary dhcp server to ensure the router is not at fault. If the temp dhcp server works. Try removing and reconfiguring the dhcp on the router again.
Re: 1 computer on LAN can't connect to router/internet
This situation sounds eerily similar to some behaviors we saw back when iPhones first came to be EVERY-FREAKING-WHERE.
I don't recall the exact symptoms, and there was a hotspot involved.... I do remember seeing the error message about lease offered unsuccessfully....
Anyway, Apple devices would have issues getting DHCP where others wouldn't. I seem to recall that we eventually discovered that the Hotspot needed to allow connections for CRL checks that Apple was doing against our GoDaddy-issued hotspot certificate. To this day, I don't know why it manifested itself as refusal to obtain a lease.... and I don't know if various updates along the way on both Mikrotik's side and on Apple's side just happened to make the DHCP thing go away right around the time we figured out to whitelist GoDaddy's CRL addresses in the IP Walled Garden....

Re: 1 computer on LAN can't connect to router/internet
I have changed the DHCP server to authoritative=yes instead of "after 2 second delay" and the one Apple device
that would not get a lease now works OK.
I don't know, however, if the changes has made it work or if it has started to work due to expiry of the lease it got
from the previous router.
So you could try this as well and see if there is a difference...

Re: 1 computer on LAN can't connect to router/internet
So I tried disabling the DHCP server and setting a manual address on my Macbook, however I was having trouble pinging the router and getting an internet connection. The router itself appears to be fine and I can ping the internet from the router via Winbox.
I tried changing the routers response to ICMP packets as mentioned in this post here:
https://aacable.wordpress.com/2011/12/0 ... -priority/
after which I could then ping the router from my Macbook. But still no internet connection!
I then unplugged the router from the switch and plugged it into a different switch socket (it's a Netgear JGS524 unmanaged switch) and the Internet connection came back and everything started working fine again!
This lasted 5 minutes, and then my internet connection disappeared and I can't ping the router any more!!
What could be going on here?

Re: 1 computer on LAN can't connect to router/internet
I have tried connecting the router directly to my laptop and it seems to work fine, but I can't leave it plugged in this way. I then tried various different ports on the switch, and they all seem to have similar problems.
I have some servers connected with static IP's and they can ping the router OK, but my laptop is currently having some issues:

Are you using a managed switch or unmanaged switch. If your computer works when coonnected directly to router then there is a problem with the switch and you either should reset config if it managed and redo. Or if it unamanged I would replace the switch.
Re: 1 computer on LAN can't connect to router/internet
It's a unmanaged switch (Netgear JGS524). I have no issues with any other devices on this switch and it is the main hub of our network. I have tried moving the RB2011 to different ports (4, 8, 21, 22) and each time it works fine for a while, and then becomes unresponsive.
I have been running the DHCP server on the original router and getting my IP address from this router at 10.0.2.1. What is strange is that I can then ping the RB2011 without any issues. However if I set static IP settings like this:
IP Address: 10.0.2.222
Network: 10.0.2.0/24
Subnet: 255.255.255.0
Gateway: 10.0.2.200
then I can't ping the RB2011. Unless I unplug it from the switch and plug it in another port which refreshes things. It's hard to determine whether it is the switch at fault as whenever I replug the RB2011 it always works for a while and it's hard to know when it fails as I have left the office by then. I can't leave my laptop connected for a week!
EDIT: I changed the subnet to 255.255.255.255 and I could instantly ping the RB2011 when my gateway is set to this router and I can access the internet. However I can't access any devices on LAN. So there seems to be an issue with using the 255.255.255.0 subnet mask.
Why is this?

Re: 1 computer on LAN can't connect to router/internet
After being able to ping the RB2011 this morning, I could suddenly no longer ping it when connected to the other router. I thought the issue could be with the port on the RB2011 instead of the switch so I just unplugged the cable from ether5 and plugged it into ether6 and the RB2011 was instantly available again. There is obviously something wrong though as I fully expect this to time out at some point, probably in a day or two.
Re: 1 computer on LAN can't connect to router/internet
Another curious thing I have noticed is that I can login to another machine which is connected to both the old router and the RB2011 and from there I can ping the RB2011. So the connection appears to be fine for that machine.
The issue seems to be other devices making a connection and maintaining it. Surely this rules out a faulty port on the switch?

Re: 1 computer on LAN can't connect to router/internet
Is it possible you're getting an IP address conflict?
Re: 1 computer on LAN can't connect to router/internet
The only DHCP server running is on the old router and is assigning addresses in the range 10.0.2.100-199
The RB2011 is set to use the address 10.0.2.200, so there should be no other devices using that address. I have just unplugged the RB2011 from the network and tried pinging it from a server that previously had no issue connecting to it and it now (unsurprisingly) can't see it. There is no response at all, which I take to mean that there is no other device using that address...

Re: 1 computer on LAN can't connect to router/internet
Another thing to check is that you are not having a mac address conflict. For instance if you backup a config from one router and pasted on the other they will have same mac addresses on corresponding ports. worth checking.
