I'm working on a project which uses .NET Remoting for communication between the client application and an object server. For development, the client, server, and MSSQL database are all running on my local development machine. When I'm working at the office, the responsiveness is just fine. However, when I work from home the speed is ...
Besides "no connection", what other failure modes should I test for? How do I simulate a high-latency link, an unreliable link, or all the other sorts of crazy stuff that will undoubtedly happen "in the wild"? How about wireless applications--how do I test the performance in a less-than-ideal WL environment? ...
Wifi support on Vista is fine, but Native Wifi on XP is half baked. NDIS 802.11 Wireless LAN Miniport Drivers only gets you part of the way there (e.g. network scanning). From what I've read (and tried), the 802.11 NDIS drivers on XP will not allow you to configure a wireless connection. You have to use the Native Wifi API in order to do...
Obviously there are security reasons to close a wireless network and it's not fun if someone is stealing your bandwidth. But how much of a problem is this? To address the first concern: Does a device on the same wireless network have any special privileges or access that an other device on the internet has? (Assume the wireless networ...
What's a good router that does dual band 2.4 GHz and 5 GHz and can run OpenWRT? ...
Is it possible to programmatically push files to a wireless SD card - like a www.eye.fi card? I use a Mac and thought I could do this using some AppleScript - but have not found a way... Derek ...
Does anyone know how to read from a promiscuous (or sniffing) device in C? I know that you need to have root access to do it, but I was wondering if anyone knew what functions were necessary to do this (normal sockets wouldn't seem to make sense here)? I want to write a real-time analysis tool for wireless traffic. ...
I'm looking for a Windows network emulator that can emulate the packet-loss & latency characteristics of a 3G wireless network. I used to use a tool from GIPs that has been end-of-life'd. I've also tried Shunra Virtual Enterprise but found it a bit too basic ...
Here is the situation: the customer machine is a Dell Inspiron 6400 running Fedora Core 9 installed from the i686 Live CD (not x86_64 as the T2400 Core Duo did not have 64-bit support). The customer wireless adapter is a ENCORE ENUWI-N USB 2.0 802.11n Wireless Adapter. My question is, how do I make this USB-wireless work with this lapt...
How can I get the BSSID / MAC (Media Access Control) address of the wireless access point my system is connected to using C#? Note that I'm interested in the BSSID of the WAP. This is different from the MAC address of the networking portion of the WAP. ...
I'm trying to make a script that sleeps my wireless card in linux. For that I'm using the deepsleep command of iwpriv: iwpriv wlan0 deepsleep 1 The problem is that this command only works if the wireless card is disconnected and disassociated. When it's connected there is no problem because if I disconnect, it disassociates automatica...
I am trying to use the error model in ns2 with wireless links, I am using ns2.33. I tried the uniform error model and the markov chain model. No errors from ns but when I am trying to find the dropped packets due to corruption I can not find any of them using either the uniform or markov models. So please help me if I made any error in ...

My code is here http://pastebin.com/f59241692 I got this error message eid@eid-laptop:~/code/ns2/noisy$ ns mixed.tcl num_nodes is set 3 INITI...
if a mobile application needs to get data from multiple servers, is it better to call each server from the mobile device, or call one server which then talks to all the other servers? "should synchronization be initiated by the server or the mobile client?" to what degree does client do the book keeping. Say if the application is mob...
I want to programmatically disable the notification I get when I connect to a wireless network. I know there is a way to disable ALL notifications (see here) but is there a way to only disable the one issued by Windows wireless Manager (i.e. wlanapi.dll). Many thanks! ...
We've got a WinForms app written in C# that has a very custom GUI. The user is not allowed to run any other applications and the user cannot go into the OS (WinXP Pro) at all. We're planning on allowing the user to connect to available wireless networks. We're going to have to create a configuration screen that displays available netwo...
Where is .mobi headed? Will the mobile devices use proprietary browsers that simplify a .com site or are they going to use browsers on a .mobi basis? I have a feeling it will be a flop... not sure though. Thanks ...
I've considered the following: Logitec Desktop MX 5500 Microsoft Wireless Entertainment Desktop 8000 But I'd like see what other programmers would recommend. ...
Are there common machines or OSs that will have problems connecting on a network where unicast ARP requests or broadcast ARP responses are not supported? I am providing a public Wi-Fi service, and considering blocking these types of ARP packet. Will this cause connectivity issues for contemporary clients? ...
I would like to get a list of the wireless networks available. Ideally this would be via some C call, but I don't mind if I have to kludge it with a system call. Even better if the required C call or program doesn't require some exotic 3rd party package. The internet seems to suggest I use sudo iwlist <interface> scan which does seem to...
