Can't see some WiFi networks, while others may

This problem only occurs on the floor of a convention center (and it takes place in several events)

(1) I see some networks, but not the designated convention center WiFi free

(2) everyone around me (a few feet), automatically detects and connects to the network

(3) I do my cell phone a hotspot.  I detect cela, but does not connect.

(4) I go back to my hotel room, easily detect / connect to the wifi at the hotel, as well as easily detect / connect to the hotspot.

I use Windows 7 Professional

Compare the networks that you can see with one of your colleagues.  You see them with the same signal strength?  If it is then maybe your ability to receive card WiFi is abnormal and the desired network arrives just in below the level that he can cope.

If this is the situation then search this forum, the support site for your computer manufacturer & their forums of users for your WiFi card.  See if other people have reported similar problems and how they fixed them.  If there is no guideline anywhere then reinstalling the card driver WiFi might be the first thing to try.

I made this suggestion because my card WiFi Dell Inspiron 1545 [Broadcom 1397] could never receive the same strength of signal to others could.  Several other users of Broadcom 1397 reported the same problem.  In this case, the solution was to uninstall Dell utility WiFi control then [Device Manager], select the WiFi card, look in its properties, driver tab and back the driver by default that came with Windows 7.  I don't pretend that your solution will be the same and I invite you to search for reports from other users.

  • Unable to see a wifi network with Atheros 5005 g wireless network card

    Hi, new to this.

    I tried Hnatyshyn best part of a month for my Equium M50 PSM59E to see a wifi network that broadcasts on 13(unlucky for some) channel.

  • Never connect some WiFi networks...

    Sometimes, when you are traveling I'll find myself looking to take advantage of the wifi airport... about 50% of the time my mac connected without problem. The rest of the time he is there right and acts like it is connected but nothing never loads in the browser.  This happens only on wifi networks that require some sort of "disagreement with the terms" screen or a paywall.   If I leave everything and restart then sometimes it fixes, but not always, and it's a terrible solution.

    Anyone know why this kind of thing happen?

    If you connect OK 50% of the time, then you are doing very well.

    AirPort WiFi networks are often overcrowded with too many users trying to use the same network at the same time. In this case, the result is slow... or not... connections. Nature of the beast, I'm afraid.

    If you belong to a club of the airline which offers separate private space for its members, the WiFi in these areas almost always works fast and reliable.

    One thing that might help a little... is to remove from the list of networks that your MacBook has signed in the past, allowing him to quickly find available networks when you need a connection.

    Open System Preferences (gear on the dock icon)

    Open Network

    Click Wireless on the left to highlight Panel

    Click the Advanced Options button at the bottom right of the window

    Here you will see a list of wireless networks that your MacBook is connected to in the past

    Click on the name of a network that you no longer need to highlight

    Then, click on the - (less) button at the bottom of the list to remove this network

    Do the same for all the other networks that you no longer need

    Click OK at the bottom right of the window

    Click apply in the next window that appears

    Close the windows and then restart your MacBook

  • Officejet2630: Officejet 4630 can't find my wifi network

    Recently moved and so got a new computer and a new internet provider. With the new internet provider comes a new router. When I try to connect my printer on the wifi network, I am unable to do so while it does not appear in the search results. So cannot be added to the network so cannot print using airprint or even via wifi... any suggestions? I tried to manually add the SSID, but again it is not picking it up. I'm at my wits end... any suggestions? !!

    Hello

    What router do you have?

    If it is a Dual Band router, make sure to enable 2.4 GHz WiFi broadcast that the printer does not support a 5 GHz band, such a can prevent the printer to your network.

    The wireless router is located between the printer?

    If make sure that's not too far, but not too close, it is recommended to not place the printer less than 1 to 2 meters from the router...

  • Can't see the computer network

    I have two computers running Windows 7 Home Premium 64 bit on my home network. In Windows Explorer under network, n ° 1 sees itself and n ° 2, but no. 2 can't see himself, i.e. cannot see no. 1.  Both can access the internet. The printer is connected to the N1 by USB (we had a lot of trouble at first with Wi - Fi so use cable for this).

    There is no RESIDENTIAL group because I understand there are IPv6 and our router does not support that. I tried the homegroup, but no. 2 could not yet see no. 1. We operate a wireless G network.

    On the computers on that network discovery is and file sharing and printer are on. Protected by password sharing is disabled.

    I saw some comments which may help to a registry cleaning. Could this be true?

    What Miss me? It left me speechless.

    Thanks for your help.

    It's fixed!

    I found another thread in that says something about the zone of confidence in their firewall. I went and looked and BINGO! The name of the area was very different in the name of the wireless network. Now it's the same thing and I have reset certain actions and we are connected.

    Yay! I thank very you much for all your hard work with this in mind.

    Moreover, there is no element of network connections in the control panel in computers. Is that how it should be?

  • Dell XPS 13 (2015) can't see 5 GHz network

    Hello

    I have the new laptop XPS of 13 2015 with Broadcom 802.11ac configuration. I am unable to see my WiFi 5 GHz network and can connect only to the 2.4 Ghz band. My router is the Asus RT-N66U. Is there a solution?

    SAL

    I had the same problem.

    If you uninstall the wireless card in Device Manager (select the option to also delete the driver) and then check for changes on the hardware, Windows uses its own built the pilot who can see 5 GHz networks.  It seems that the driver from the Dell Web site is borked.

    My concern is that this driver is not updated, so I would like to know where to get more drivers for this device.

  • Strangest thing: iPhones can't see the wireless network. Why not?

    Suddenly, an iPhone 5 and an iPhone 6 were not connected to the home network. I thought that the wireless router was to have a hiccup. Reset it and still no. Control a connected computer and internet. Thought that it was a wireless problem, but check the settings (I don't mess with) and they are fine. BUT, I realized my iPad is always connected to the network. IPhones don't even see the wireless network. SSID always broadcast on. I tried to enter the SSID and password manually, but iPhones say that the network does not exist. It's the strangest thing. What would make the invisible network for phones all of a sudden? Both phones are differnet OS running. One is the latest version, probably the previous version. It's a FiOS Actiontec router/router wireless. Everyone has heard of such a thing? I do not understand how it is possible...

    Try this on an iPhone. No matter which even with other iOS.

    Tap settings > general > reset > reset network settings

    You will need to enter the password for Wi - Fi.

    Hello

    a new Pavilion 15 with the network card wireless Realtek rtl8188ee - all drivers up to date.

    I have a Netgear router which is dual band and there is a network of 11g and 11n.

    I can connect and use the network of 11g all very well.

    But I don't even see the 11n network.

    Any thoughts?

    If you mean that you cannot connect to the 5.0 GHz band, it's because the wireless RTL8188EE is a unique card band (2.4 GHz) only.
