  • Problem setting up HP PhotoSmart C4783

    - by ProfKaos
    I am trying to get several PC's on a network to connect to my client's new wireless printer, the C4783. I initially installed the whole HP 'tsumami of software' the comes with the printer onto my laptop, connected to the printer over USB, and corrected it's networking config. My laptop now also can connect to and print on the printer over the wireless network, as is intended for all PC's. However, when I try and install the HP software on my client's netbook, the HP software cannot find the printer. Firewall was turned off during this time, so doesn't play a role. I tried re-installing all software, but I initially only got a "Repair" or "Uninstall". Choosing Uninstall triggers a lengthy process that ends with a sudden and forceful restart, after which the same "Repair" or "Uninstall" choices are present. Looks like uninstall doesn't. Any suggestions as to how I can begin diagnosing why my laptop has no problem connecting to the printer, but two others do? Wireless is unsecured, and no, nobody has to know where I am right now. :-)

  • is it good to have or difference between ADSL Modem+WiFi Router and Separate ADSL Modem & Wi-Fi Router?

    - by vikas devde
    I have ADSL2 Modem which I got from my service provider, now I want to setup wireless(Wi-Fi) in my home. I went to shop, where I came to know that there are routers which come up with modem also but they are priced lil higher than the only wi-fi routers. Now it is obvious that I should go for only wi-fi one, as I already have modem. My question is, is there any difference between ADSL+router and only router? I think if I use ADSL+router, the speed will increase lilbit, as modem does modulate and demodulate signals, and router also generates wireless signal, that is time to take conversions is doubled, and if I use ADSL+modem, it will directly convert the signals to wireless, and time will be saved, so the overall speed will increase lilbit. This is what my concept is(Which might be wrong). What do you guys would suggest me? should I take my current modem away and buy an ADSL+router or I should keep my modem and buy only wi-fi one. Please tell me the difference and suggest me which one I should go with, and also suggest me which company router I should go for.

  • "Safe" personal router use on apartment-wide network

    - by noisetank
    I recently moved into an apartment with internet included in my rent. This was a boon at first, but now I'm feeling limited. To get devices connected (wired or wireless), I have to whitelist the MAC addresses on mycampusnet.com. This is annoying (considering I'm well over the 10 device limit including my roommate's stuff), but what's really driving me mad is that I don't seem to have any semblance of a "local" network. I've relied heavily on static IPs and port forwarding in the past (accessing NAS and remote desktop) and (as far as I can understand), that functionality is nonexistent without my router set up. Also, as my wired and wireless devices don't always seem to make it onto the same subnet, I'm unable to use any of my iDevices with my Apple TV (I can, however, mirror to no less than four strangers' Apple TVs at any moment, which is a whole other level of discomforting). I've talked to the head of the apartment complex and she told me that they personally don't have any issue with my using a router, but the provider (CampusConnect) does not currently allow it. Apparently, enough people have put in complaints/requests about the restriction (the apartments are for graduate students and University staff, many of which need to set up things like VPNs for work reasons) to open up some sort of ticket to get the functionality in place, but all the calls I've made to get status updates have been a waste of time. My question is: If I plugged my router into the apartment network, what would happen? I've been told already that personal routers would "interfere with the wireless" and that they would shut my port down if I used one, but is that a legitimate thing or just something made up that sounds real to keep the average Joe from pushing it further? I'm guessing there's some way of configuring my router to keep it from disrupting the rest of the network, but it's not something they want to tell me for obvious reasons. Am I right? And if so, what are the chances that they'd notice the difference in traffic or whatever and shut off my port?

  • Configuring WPA WiFi in Ubuntu 10.10

    - by sma
    Hello, I am trying to configure my wireless network on my laptop running Ubuntu 10.10 and am having a bit of difficulty. I am a complete Linux newb, but want to learn it, hence the reason I'm trying to set this up. Here's the vitals: It is a Gateway 600 YG2 laptop. It was previously running Windows XP, but I installed Ubuntu 10.10 in place of it (not a dual boot, I removed XP altogether). I have an old wireless card that I'm trying to resurrect. I haven't really used the card in a couple years, but it seems to still work, I just can't connect to my home's wireless network. The card is a Linksys WPC11 v2.5. When I plug it in, Ubuntu recognizes the network, but won't connect to it. My home network uses WPA encryption and the only connection type that Ubuntu's network manager is giving me is WEP and then it asks for a key -- I have no idea what that key should be. So, basically, I'm asking, is there a way I can instead connect through WPA? I've tried creating a new connection in network manager, but that won't work, it keeps falling back to the WEP connection and asking me for a key. I have tried to install the XP driver using ndiswrapper but I don't know if that's working or not. Is there a way to tell if: A) the card is working as it should B) the correct drivers are installed (again, I installed the XP one using ndiswrapper NET8180.INF, but I'm not sure what to do next) Any help would be appreciated. Thank you.

  • Enterprise Wireless Authentication without Active Directory

    - by ank
    We are in the process of redoing our wireless access network and would like to know if there is any method to get Windows clients/users access to the network using 802.1x WITHOUT having an Active Directory server for authentication and WITHOUT installing additional software on each and every client. Note that we already use Radius servers, LDAP servers (all on CentOS). Users employ a variety of clients including Windows, Mac, Linux, Android, iOS.

  • ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages

    - by DigiMortal
    If you are using AppFabric Access Control Services to authenticate users when they log in to your community site using Live ID, Google or some other popular identity provider, you need more than AuthorizeAttribute to make sure that users can access the content that is there for authenticated users only. In this posting I will show you hot to extend the AuthorizeAttribute so users must also have user profile filled. Semi-authorized users When user is authenticated through external identity provider then not all identity providers give us user name or other information we ask users when they join with our site. What all identity providers have in common is unique ID that helps you identify the user. Example. Users authenticated through Windows Live ID by AppFabric ACS have no name specified. Google’s identity provider is able to provide you with user name and e-mail address if user agrees to publish this information to you. They both give you unique ID of user when user is successfully authenticated in their service. There is logical shift between ASP.NET and my site when considering user as authorized. For ASP.NET MVC user is authorized when user has identity. For my site user is authorized when user has profile and row in my users table. Having profile means that user has unique username in my system and he or she is always identified by this username by other users. My solution is simple: I created my own action filter attribute that makes sure if user has profile to access given method and if user has no profile then browser is redirected to join page. Illustrating the problem Usually we restrict access to page using AuthorizeAttribute. Code is something like this. [Authorize] public ActionResult Details(string id) {     var profile = _userRepository.GetUserByUserName(id);     return View(profile); } If this page is only for site users and we have user profiles then all users – the ones that have profile and all the others that are just authenticated – can access the information. It is okay because all these users have successfully logged in in some service that is supported by AppFabric ACS. In my site the users with no profile are in grey spot. They are on half way to be users because they have no username and profile on my site yet. So looking at the image above again we need something that adds profile existence condition to user-only content. [ProfileRequired] public ActionResult Details(string id) {     var profile = _userRepository.GetUserByUserName(id);     return View(profile); } Now, this attribute will solve our problem as soon as we implement it. ProfileRequiredAttribute: Profiles are required to be fully authorized Here is my implementation of ProfileRequiredAttribute. It is pretty new and right now it is more like working draft but you can already play with it. public class ProfileRequiredAttribute : AuthorizeAttribute {     private readonly string _redirectUrl;       public ProfileRequiredAttribute()     {         _redirectUrl = ConfigurationManager.AppSettings["JoinUrl"];         if (string.IsNullOrWhiteSpace(_redirectUrl))             _redirectUrl = "~/";     }              public override void OnAuthorization(AuthorizationContext filterContext)     {         base.OnAuthorization(filterContext);           var httpContext = filterContext.HttpContext;         var identity = httpContext.User.Identity;           if (!identity.IsAuthenticated || identity.GetProfile() == null)             if(filterContext.Result == null)                 httpContext.Response.Redirect(_redirectUrl);          } } All methods with this attribute work as follows: if user is not authenticated then he or she is redirected to AppFabric ACS identity provider selection page, if user is authenticated but has no profile then user is by default redirected to main page of site but if you have application setting with name JoinUrl then user is redirected to this URL. First case is handled by AuthorizeAttribute and the second one is handled by custom logic in ProfileRequiredAttribute class. GetProfile() extension method To get user profile using less code in places where profiles are needed I wrote GetProfile() extension method for IIdentity interface. There are some more extension methods that read out user and identity provider identifier from claims and based on this information user profile is read from database. If you take this code with copy and paste I am sure it doesn’t work for you but you get the idea. public static User GetProfile(this IIdentity identity) {     if (identity == null)         return null;       var context = HttpContext.Current;     if (context.Items["UserProfile"] != null)         return context.Items["UserProfile"] as User;       var provider = identity.GetIdentityProvider();     var nameId = identity.GetNameIdentifier();       var rep = ObjectFactory.GetInstance<IUserRepository>();     var profile = rep.GetUserByProviderAndNameId(provider, nameId);       context.Items["UserProfile"] = profile;       return profile; } To avoid round trips to database I cache user profile to current request because the chance that profile gets changed meanwhile is very minimal. The other reason is maybe more tricky – profile objects are coming from Entity Framework context and context has also HTTP request as lifecycle. Conclusion This posting gave you some ideas how to finish user profiles stuff when you use AppFabric ACS as external authentication provider. Although there was little shift between us and ASP.NET MVC with interpretation of “authorized” we were easily able to solve the problem by extending AuthorizeAttribute to get all our requirements fulfilled. We also write extension method for IIdentity that returns as user profile based on username and caches the profile in HTTP request scope.

  • Can I connect an external antenna to a range extender?

    - by ercan
    I live in a kind of dormitory and the next access point is 60 meters away from my room. So I bought a range extender (TP-Link WA730RE) and installed it into my room in the same height as the access point. But my problem is still not solved. The reception is slightly better but my connection still gets broken every two minutes. The antenna that comes with this range extender was 4dB. My question is, can I buy an 8dB external antenna (like this one: http://www.amazon.com/TP-Link-TL-ANT2408C-Desktop-Omni-Directional-Antenna/dp/B0034CQSKW/ref=sr_1_14?ie=UTF8&qid=1332074993&sr=8-14) and replace it with the antenna that comes with the range extender? Or is this external antenna only suitable for the "receiver" end of the connection, i.e. the computer?

  • Difference between indoor and outdoor WiFi Access Points

    - by aaron-cook
    Does anyone know if there is an operational difference between what is classified as an 'indoor' wifi access point and an 'outdoor' wifi access point. I'm speaking specifically to its operation rather than things like whether its enclosure is weather proof or not. And I'm also referring to the access point itself as opposed to the antenna used.

  • Wireless Access Point stopped working

    - by Alex Pritchard
    I have a simple LAN set up at home using a Linksys WRT54GSV4 as my primary router and an Encore ENHWI-2AN3 as an access point. I connect the Encore to the Linksys by running a cable from one of the Linksys LAN ports into the Encore WAN input. I originally configured this using the Encore setup wizard, setting the device up in AP Router Mode. It detected the input network and worked about as expected, creating a second network that used my primary network to connect to the internet. It worked fine for about 2 weeks, then abruptly cut out today. I checked to make sure the network was still live through the cable going into the Encore (provides internet when connected to a laptop directly) and that devices are still able to connect to the network being broadcast by the Encore. When I try to rerun the connection wizard on the Encore, I receive the message "No Services found in WAN port." The WAN Settings is no longer retrieving a dynamic ip from the line. I tried providing a static IP, assigning an IP address within the subnet range of my primary router that wasn't being used and pointing the Default Gateway to the Linksys IP, but this did not work either. When I plug the cable into the WAN port, an internet light comes on that is not lit when a live network is not connected. I've tried doing a hard reset on the Encore (held down the rest button until the lights flashed, reconfigured from scratch), but the WAN settings are still not detected. Also tried powering off and on the modem, linksys, and encore. Any suggestions would be appreciated!

  • C++ fixed point library?

    - by uj2
    I am looking for a free C++ fixed point library (Mainly for use with embedded devices, not for arbitrary precision math). Basically, the requirements are: No unnecessary runtime overhead: whatever can be done at compile time, should be done at compile time. Ability to transparently switch code between fixed and floating point, with no inherent overhead. Fixed point math functions. There's no much point using fixed point if you need to cast back and forth in order to take a square root. Small footprint. Any suggestions?

  • Access 2007 - Forms created on the fly

    - by glinch
    Hi There, Hopefully I can find some words of advice from somebody. Is it possible to create forms 'on-the fly' so to speak in MS-Access 2007 I have a structure of tables: tblCustomer tblQuestAns A customer may answer the questionnaire answers many times as they relate to all products. I propose to hopefully have an initial input form that will ask how many products of which there could be more than 1 eg: TV, Video (say the user selects 2) On entering that data the next form should hopefully update itself to include the list of questions eg TV Q1, Q2 Q3 - Video (1) Q1, Q2 Q3 - Video (2) Q1, Q2 Q3 Is that possible? Any point in the right direction would be appreciated. Thanks Noel
