I have level up of my internet bandwidth from 100mbps to 300mps, I tested from modem directly, I got 300mpbs. On the other hand, when I tested from Mikrotik-Routerboard RB1100AHx4 version, I got 100mbps, anyone can help me to resolve it?
I have checked menu of Filter, Queues, and others, but I don't get anything from this..

In Miniport drivers we have two status indications(NDIS_STATUS_MEDIA_CONNECT/NDIS_STATUS_MEDIA_DISCONNECT) to know whether LAN is disconnected or not.
Can we use the same indications in LWF to know the status of Media associated with LAN. I have two scenarios that I want get the indications or handles for.
When Wire connected to NIC is pulled and re-connected.
When two PC's are connected through a wire, I will power down the other PC where LWF is not running.
Appreciate your help.
Thanks
Drivers written in the last 10 years should not use NDIS_STATUS_MEDIA_CONNECT or NDIS_STATUS_MEDIA_DISCONECT. Those were retired with NDIS 5.x. Instead, use NDIS_STATUS_LINK_STATE.
Filter drivers may listen for NDIS_STATUS_LINK_STATE. They can also query the current link state at any time, by issuing OID_GEN_LINK_STATE.
If your filter originates NBLs, I encourage you to monitor the link state. It's just a waste of CPU cycles to try and originate NBLs when the link is down -- the packets will just get returned to you.
So basically I have a WiFi network which has internet, then I have a LAN network that does not have internet its just a dummy internet so I can test things with higher speeds. But here's my issue since the LAN doesn't have internet when I plug it in my computer doesn't keep internet even though I am still connected to my WiFi which has internet. any solutions?
sorry guys. I just figured out that both the gateways on my routers were the same and that was causing the issue.
As the question states, I have two ethernet devices I need to use. A wifi hotspot for general traffic as well as a LAN connection for local traffic (192.168.1.*). Right now the wifi receives all traffic and disregards the existence of my local LAN devices. I am trying to communicate with this device using python's urllib2 and basic http fetches. The program works partially when I turn one or the other off (turning wifi off makes the LAN code work, and turning LAN off makes wifi/general traffic code work). I believe this is more of an operating system issue than a programming question, but I might be mistaken. I have been messing with the Ethernet setting in system preferences, but nothing has been working so far.
Thanks for the help.
Depending on your needs and degrees of freedom, you can:
1) Easiest: If you can control one or both network ranges, you can put wifi and LAN on different subnets. For example, 192.168.2.* could be LAN traffic, and 192.168.1.* could be wifi. If only the WiFi side has a gateway, then all traffic except 2.* traffic should route through WiFi, and all 1.* traffic goes to the LAN. No change to your computer.
2) Medium: if you don't control the networks, you can define routing rules for the two ports. This lets you say certain IP addresses should be reached thru wifi, vs others thru LAN port. An example in Linux, which I think should work on OS X too: http://linux-ip.net/html/routing-tables.html The trickiest thing is to make sure you won't get in the way when you're in someone else's network. You can do this by creating narrow routing rules, or turning them off when you don't need them. It sounds like you're doing this from a python program, so maybe the program could turn this on and off at start and finish.
3) Slightly more exotic: I wasn't totally sure from your question, but if you're trying to do load balancing (not separate networks), you could create rules to bond together two network ports and spread traffic across them. This isn't something I've done, but real network engineers know how to set this stuff up.
I could expand on one of these if you clarify what you're trying to do and what degrees of freedom you have.
For somebody don't want to do the study you can simply repeat my steps:
Open system preferences
click on Network
(ensure the precedence, first thunderbolt then wifi) click on thunderbolt
Configure IPv4 choose manually
delete router
done!
I have exactly the same user case. But I read this without any network knowledge.
I achieved this by simply following #Nils' 1) instructions. I only understand theses instructions after reading this link
My application communicates with several GSM electric controllers, that means that I have to send anywhere between one to twenty messages every few hours. right now I'm working with HUAWEI Mobile Connect - 3G. it is a USB device that uses a comm port for the pc communication and I'm using GSMComm to send messages and read/delete messages from the device.
Every two seconds I'm checking the device's storage, and if there is any message, I will then read it and store it locally and then clear the device's storage. I'm not sure if I'm working correctly, but it seems to me as if it is a very unreliable device:
Every time I boot my machine, I must remove the device from the USB or my machine will get stuck at the BIOS start up screen (or whatever the name is).
Very frequently the comm port can become unavailable for some reason. I have to close and re open the port, and at times that may not even help.
In the production machine of my client, when he uses one of his software's that utilize the first comm port, he will get a warning message from the software about problems in the port if the device is plugged in (the device port is around 28 or something).
If you've been using a device which you consider reliable, or have been working with the same device as I work with, or you just think that I'm doing it wrong, I'd like to get an advice from you.
Thanks.
This sounds like an issue with your modem. Have you tried any other models? Consumer USB models tend to be unreliable. The preferred method, though slightly more expensive, is using a commercial grade modem in situations where you need the reliability.
Some modems to look at:
Wavecom Fastrack
Sierra Wireless Airlink
These use a serial port or ethernet to communicate with the host which is far more reliable. Serial ports may not be available in your particular situation but even a USB to RS232 adapter will be more reliable.
One further option is to use a smartphone, there are several applications that you can act as a gateway through HTTP.
SMS Gateway for Android:

i have not used this method, but it seems like some people are having luck with it. it may not be any more reliable then your USB modem though.
Hope that answers your question.
I have used WaveCom's modem for sending messages in bulks and found it to be reliable. One difference though, in my implementation was i used Kannel as an SMSC, so my queues were automatically handled by Kannel. But sending multiple requests like 40+ per minute didnt pose any problems for me.
Hope this helps.
First off, you guys are all really helpful - thank you a lot!
Is there a way to figure out what type of network a Mac is connected to? WiFi? Cable? USB Modem? Any Cocoa / Foundation framework I can use to figure that out?
Thank you,
Matthias
You can tell whether the Mac is using WiFi, whether it is using a modem, and whether it is using hard Ethernet (which could be cable, DSL, or something else). Note that these are not mutually exclusive, there may be multiple connections of a single type (I have two Ethernet ports, for example), and that being connected to an IP network does not necessarily mean connection to the Internet.
You'll probably find the System Configuration API helpful. See also the framework reference.
You may also want to look at the source for HardwareGrowler in the Extras folder of the Growl source code.
You could ask for the route table and see what the default route is, that would tell you to some degree of accuracy what the active connection is.
This obviously has a lot to do with how you define 'some degree of accuracy'. Generally the main internet connection will also be the default route. I'm assuming you also want active connection to mean 'internet connection'.
netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 192.168.0.1 UGSc 22 14 en1
so for me, my default route goes out the en1 interface. I think you need to be a lot more specific on what you mean by 'active/current' means to you.
CAVEAT: just because my default gw is on en1, does not necessarily mean that's where all my inet traffic goes. (it happens to be true in my case, but don't count on it as truth, but would probably be correct more than half the time).
