  My HP Pavilion 14e016tx (win 7, 64-bit, rt3290 ralink 802.11) does not detect WiFi connections.

• ConnectionFactory cannot create the WiFi connection

  I tried this code example, and it returns null ConnectionDescriptor when I only have the wifi connection:

  cf = new ConnectionFactory();
  cf.setPreferredTransportTypes(new int[]{
      TransportInfo.TRANSPORT_TCP_WIFI,
      TransportInfo.TRANSPORT_TCP_CELLULAR,
      TransportInfo.TRANSPORT_WAP,
      TransportInfo.TRANSPORT_WAP2,
      TransportInfo.TRANSPORT_MDS,
      TransportInfo.TRANSPORT_BIS_B
  });
  cf.setAttemptsLimit(2);
  cf.setConnectionTimeout(10000);
  ConnectionDescriptor descr = cf.getConnection("http://www.google.com");
  StringBuffer buff = new StringBuffer();
  if(descr == null){
      buff.append("no descriptor");
  }else{
      buff.append(descr.getTransportDescriptor().getTransportType() + ";" + descr.getUrl());
      try {
      descr.getConnection().close();
      } catch (Exception e) {
          System.out.println("===>conn close error:" + e.getMessage() + ";" + e.getClass().getName());
      }
  }
  

  I tested with the mobile network and it works well and returns the connection descriptor non-zero but when I try with the wifi only and always returns null.

  I tried to access Google.com on the bb browser and it opens.

  However, the connection is slow and it loads for a while before opening google. Is this the reason why I get null handle or its something else?

  Well I solved it.

  It turned out that I had activated the VPN profile to the wifi network. When I disable the code works ok.

  But this raises the question why can't make a connection http via wifi with active VPN profile. I can always open google.com in the browser.

  I'll make a new thread for this question.

• BlackBerry Smartphones Blackberry Priv and Fuji Instax share App (needs to control WiFi connections)

  Hey all,.

  as I have found no e-mail address to communicate directly with Blackberry on this problem (I hate to use Twitter, their support is atrocious (using answers pre-formulated to 'help you')), I hope I can find help from you guys.

  When you use the 'Instax Share' app to print photos from my private, it does not work.

  First, you will need to connect to the printer via WiFi (this step works), but I can't change the printer settings in the app. Can I not send my photos to the printer.

  When I try, I get the error message "no printer not found", even though I am obviously linked to the unit.

  When you check the extended permission settings, the field that would allow the application control WiFi connections is gray. The only parameters that can be modified are access to contacts, memory, taking photos and video and GPS.

  Anyone got a good idea on how to solve this problem?

  My guess: Priv Android is coded too sure. Furthermore, I use Android 6.0.1.

  P.S.: the application works on any non-Blackberry-Android phone (rooted and without root).

  OK, so to clarify, this isn't a device of BES. In addition, you can control completely independent WiFi connections on the device. But the application cannot control the WiFi connections, that he must perform in order to function. Fix?

  If it is accurate, then it continues to point to the application itself, not the device or the device OS... When you installed the application, he should have asked approve you a variety of security access so that it will run... If you do not approve those, you have limited it. If she has not asked for approval, then the application developer needs to fix this.

• BlackBerry smartphone Bold 9780 cannot use BB browser when wifi connected

  I recently started using a new BB Bold 9780 (BB6).

  It of a beautiful phone... and navigates very well with GPRS / 3G.

  However, if I turn on wifi, (connected to my home wireless router) the browser does not at all.

  "Cannot find the requested server.

  I have a Netgear router and it is very good for other devices.

  BB 9780 wifi session is set to WPA

  I have a dataplan with Virgin.

  I conclude that the wifi does not work and it would be very disappointing... and sounds weird!

  When all sales representatives say that he is an active wifi device.

  Does anyone have any tips or tricks?

  I was wondering if Opera 5.1 might help - but the opera died when I tried to launch it!

  Thank you very much

  Chrism

  Well, I finally fixed it.

  My BB was not able to connect to my Netgear router, but it could connect with happiness with the wifi of my neighbor.

  I turned off the WMM security setting on my Netgear router advanced setting Panel.

  Bing, the BB is now wifi.

• C50D-A-133 satellite detect WIFI connection but cannot connect

  Hello world!

  I have a problem with the internet connection from my laptop.
  Earlier this week, I noticed that my internet is very slow.

  Now a few days later I can not connect with my wireless network more.

  My other laptop can still connect with the network, so I think that there is something wrong with the windows drivers 8.1?

  Because I've read some things other people who have had the same problem but I couldn't solve the problem.

  It's a toshiba Satellite C50D-A-133 with qualcomm atheros ar956x as an internet adapter

  Can someone help me with this problem?

  Kind regards

  {quote} My other laptop can still connect with the network, so I think that there is something wrong with the windows drivers 8.1? {quote}

  According to your post, you were able to connect the laptop to the router WLan.
  In this case, the WiFi connection has been established correctly.

  I put t think there is a problem with the laptop s Wlan connection. Your WLan router is probably some problems and that is why I recommend to reset the router.

  In addition, you could test the LAN connection.
  In case you have a problem with the connection to the local network, the configuration of the router should be checked.

  Hi Amanda

  If you want to be sure that you only use wifi data, then on manage the connection you can turn off your Mobile network. But you have to turn on your data Services, allowing data packets to enter your device With Data Service Off in your device, you can use these data services.

• WiFi connectivity weird when I plug in the USB Flash drive?

  I found this WiFi connection problem a few days ago, when I plugged a USB Flash drive in "USB port right side' of my MacBook Pro.

  Every time when USB , WiFi won't work - the connection is lost and can not connect to any hotspot even turn the WiFi market.

  I found more weird, ONLY this brand and model key USB could be the abnormal Mac WiFi.

  

  This problem will not happen to another USB port even I put the Flash drive in the left side, USB port, weird isn't?

  Conclusion, this flash drive cannot be used with USB port on the RIGHT side, another USB port works fine. If WiFi don't work.

  All other USB devices I've owned are working very well on the USB ports on the right or left side.

  Could Apple support or any helps me to understand why this happen?

  PS. I had the Apple's Diagnostics and received a message "no problem found".

  PS #2. Right - same USB port side and next to the HDMI port on MacBook Pro 13 "model 2015" (snack for someone who confuse average left or right)

• Satellite L350 - WIFI connection problems when it is plugged in to recharge.

  I have a problem with my laptop - whenever I have it plug in to recharge after 10 minutes my Wifi connection goes down, it can detect my wifi network but cannot connect. However when my laptop not charging it remains connected until the battery goes down. I can not think of all the solutions and can't find answers on the internet. I am sure that this isn't my wifi network that is the problem as I have said, it connects and remains connected to each time when no charging current.

  Any help would be really appreciated.

• Trek PR2000 DHCP problems, maintains a drop connections, perhaps workaround

  Hello!

  A few days ago, I bought the new Netgear Trek PR2000 mobile wireless router. Goal was to have a point of contact for all my devices while traveling and be able to connect to a hotspot or wifi in the hotel.

  Configuration has been fine and I was able to connect to my home network in wireless client mode. My router is a TP-Link TL-WR1043ND running OpenWrt 12.09 Attitude Adjustment, wifi with WPA2-AES, DHCP service.

  The Trek has been able to connect, and the whole system was running. Unfortunately, I realized, that the Trek has kept falling connections every 3-5 minutes with the genius of Netgear annoying pop up and try to re-establish a connection. Sometimes it worked, then the Trek cannot connect at all.

  Since I read that OpenWrt Attitude Adjustment can be problems with some wifi connections, I have improved my WR1043ND barrier breaker. The connection drops continued, including OSX almost every minute. The WR1043ND showed various DHCP-wifi-a failed-to-recognize-errors and in his diary.

  After trying all possible setting changes in the Trek-config (and shortly before returning the Trek), I found something as a workaround. In the Trek-config, I disabled the DHCP Server for the LAN area and assigned static IP addresses to connecting clients. Well at least so far, it seems to work very well. No more connections, no more boring engineering arise not interrupted and try to reconnect, the system seems to work.

  But for now, I'm a little confused as to the reason. In my view, the Trek connects to a hotspot and gets an IP address assigned by DHCP from hotspot. Then the Trek uses NAT to connect the clients attached to the internet. Actually the IP addresses of the DHCP assigned by the Trek to customers connected to the LAN area shouldn't affect hotspot NETWORK settings at all. Normally the IP address and private DNS settings are just for private clients LAN, aren't they? If I'm not completely wrong in my assumption, there could be a bug in the DHCP server on the hike or the way how dynamic the client LAN IPs are handled. From the point where I changed to static IP in the LAN client, there was no error message in the log of the WR1043ND.

  Strange thing... Maybe someone could correct me if my assumptions are wrong? BTW, I use the stock PR2000 Trek firmware (which is something like 1.0.0.9) since there is no other is available.

  Thank you.

  @hksteve I wish to inform you that the fix is now available from our download page.

  Feel free to update your firmware and provide feedback.

  Thank you!

• Loss of WiFi connection and screen flickering on T440p (external)

  It is a brand new TP T440p and I installed a new copy of Windows Pro 8.1 on it (fired). I applied all the updates of Windows and installed all updates of drivers/BIOS Lenovo system update.

  The computer works fine, but when I put it to sleep and wake it back up, the external monitor is almost always flickering (there is a movement of 1 mm left and right, line by line - I'll shoot a video, if the camera is capable of capturing the movement, because it is very "thin"). Sometimes it stops after a few minutes, but most of the time that I need to re - start the computer.

  In addition, not always, but several times WiFi connection is lost and I cannot reconnect unless I restart the computer.

  It is a BIG productivity killer so I would appreciate help from anyone who knows what could be wrong. Thank you.

  Here are my characteristics of system in detail, if it helps:

  EDIT: here's a video of the flashing screen: https://www.youtube.com/watch?v=zV38PC_a0l4

  Change the 720 p video and capture full screen in the view of the anomaliy. Thank you.

  I solved all problems by installing the latest drivers from Intel (graphics & WiFI) and Nvidia.

  All I can say is - use not the Lenovo provided drivers. After you have installed Windows 8.1, just run all the updates and search the latest drivers manually. Drivers Lenovo just foires my computer. Guys not happy.

• disappointment that printshare cannot print with wifi

  Hello

  is it me or is it a huge disappointment printshare cannot print unlimited pages in wifi connect printed. only 20 pages? is it serious? Anyone know of any alternative to print via wifi unlimited times or I just have to export all to gmail in the form of png images and then print from my computer.

  The printershare limit is due to the fact that Lenovo has not in fact given us full of printershare versions, but rather the same demo that you can download the free market... Please see my thread on purchase if you want to go this route, because the on-board Lenovo version is some kind of scam (same as the regular version of the Android market but you can not use it on other devices).

  Lenovo has been quite misleading in their marketing when he came to this apps bundled $ 150.

• "Windows cannot configure this wireless connection".

  I (birthday gift) a laptop Dell Inspiron 1011 with Windows XP Home Edition.  It has a "Dell Wireless 1397 WLAN Mini Card".  It works wirelessly at home but when far and try using WiFi access points, if I am looking for available networks, it comes up with "Windows cannot configure this wireless connection".  (She also comes up with this message at home if I search for the network, but works OK on everything that I established House).  I searched online and found a "fix" of Microsoft, but when I tried to use a time warning that "this type of file can harm my computer" so I gave up.

  Another area, I looked explained that the software other than Windows ensured control WiFi and it was not recommended to disable it.  (No doubt, it was the Dell software?)

  I'm very PC not literate and would appreciate any help very simple!

  Hi sligo123

  You can find this a bit confusing link.  I suggest that you enable the automatic configuration service (service Windows uses to control the wireless, rather than the Dell software).  Heres how:

  1. click on start, then run

  2. in the box, type C:/Windows\system32\services.msc/s

  3. click on OK

  4. in the window that appears, you should have a full range of services, scroll down until you find Windows Zero Configuration - double click on it

  5. in the box, make sure that the automatic option is selected in the drop-down list box.  Then click on the Start button.

  Try and then try to connect to the wireless network (you may have to connect to your home network)

  If this does not help, please post back here and we can try something else.

  Kind regards
