WRT54G3G-AT Blocks only browser access to the Internet.

We have a WRTG54G3G router with Sierra Wireless AC881 card. Latest firmware, version 2.02.2. Good, steady AT&T signal. Works consistently when the Sierra card is directly in one of the three laptops we use. But, when using the router, many times one or more (but so far never all) of the laptops will lose browser connectivity. A change between IE or Mozilla gives the same result. Strangest part is that we can access http://192.168.1.1 but not the Internet beyond. If the problem crops up, we can put the laptop on a wired connection and often get through ---BUT -- after a while, the wired connection will stop as well. No amount of rebooting of any or all components helps. When a laptop is "locked out", it still has network connectivity. For example, I can ping www.yahoo.com and get packets back. Also, NSlookup resolves www.yahoo.com. It appears as if port 80 becomes blocked. The next day, a laptop that failed the night before will usually work fine. I have reviewed every setting in the router. There are no special rules or anything odd in the way we intend to use this router.

I have considered restoring factory defaults and starting over with the configuration. I think that's what you are suggesting? If so, instinct tells me not to restore from the image I have saved to disk. Instead, don't you think the best path is to hand configure it from notes? On the other hand, I don't agree with the "losing signal" theory as other laptops can still access whilst the one is not able to function. Additionally, a laptop that is locked out from the router can function just fine if I move the AirCard from the router to the laptop that has been locked out. Of course, that precludes the other workers from functioning... Thank you for the input, I'll give it a try. Allen

  • I have accidentally blocked Firefox's access to the internet, how do I unblock it?

    Earlier I saw a popup while I was browsing that said that Firefox was trying to access my internet, and at the time this seemed suspicious. I don't know why, but I pressed "block" which, in return, blocked my entire access of the internet through Firefox. I tried reinstalling Firefox, and I also tried to do stuff with the firewall but I didn't understand what to do. How could I allow Firefox to access the internet again?

    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • Is there any way to block access to the internet?  Allowing only calls and texts?

  • How can I set up and email address for my grandson without giving him general access to the internet? email only

    My grandson's school needs him to have his own email address. For some reason, his is not able to use my address. I do not want him to have general access to the internet. His older brother caused my computer to be infected with a virus in a very short time. It took three weeks and one hundred dollars to get the use of my computer back.
    I do not want him to have access to the internet, but his school wants him to have an email address to communicate with him about school work. I am concerned that once he has an email address, someone (not the school) will send him a web site address in a message and he will be able to just click on it to get into the internet.

    You can use an email program (e.g. Outlook Express or Windows Live or Thunderbird) and disable HTML for that email (text only mode) to access the email account. You can create a new email account if your your ISP supports it or use a online service that allows POP3 access with an email program (most popular services allow that).

  • RD Web Access From The Internet/External

    I’m requesting help with accessing from the internet (external web) a RD Web Access Connection (SSL) that I setup and configured on a Windows 2008 R2 Server.
    My setup is as follows. All server rolls are configured and running on one Windows 2008 R2 Server (VM).
    1.      
    Remote Desktop Services
    a.      
    RemoteApp Manager
    b.     
    Remote Desktop Connection Manager

    RD Gateway Manager

    f.       
    Remote Desktop Licensing
    2.      
    Web Server (IIS)
    All my configurations are working perfectly internal/intranet. I can access all published applications and remote desktop connectivity via (SSL) from IE 9 web browser.
    The URL that is used internally is: (https://ServerName/RDWEB).
    When I attempt to connect via the internet I’m getting an “Internet Explorer cannot display the webpage” message.
    I’m using Dynamic DNS to access the server hosting the (IIS Remote Access Web Page URL), example (https://DDNS/RDWEB). I’ve opened ports 443 & 80
    on my Untangle firewall, also port forwarding for 3389.
    Any and all help will be appreciated.

    Freek,
    Thank you for your response. I tested Telnet as you suggested, and both FQDN and IP address were able to establish a Telnet connection to my RD Web Access Server.
    The “NSLOOKUP” resolved the DNS server name. Also, I am able to us the IP address, URL (https://IP/REWEB) in IE9 to browse to my RD Web Access Server site. The above should confirm DNS IS working correctly within my internal network.
    My connection issue is from external/internet access to my RD Web Access Server site. All my networked devices (internal) are natted IP assigned behind an “Untangle
    Gateway” firewall and routable internally only.
    Although, I’ve opened ports, created firewall rules to pass traffic on ports 443, 3389 my problem still exist. Since my internal natted devices are not routable
    from the internet, I am using a DDNS host URL from (www.dyndns.org) to route from the internet to my internal site server. As it stands now, I suspect the problem maybe at the Untangle Gateway”. I will focus my attention there.
    Thank you again for your help.

  • How do I setup my Time Capsule (3rd Generation) to be accessed from the internet while I'm traveling?

    How do I setup my Time Capsule (3rd Generation) to be accessed from the internet while I'm traveling? It is installed on my home network behind my TWC broadband router.

    Ok.. since the TWC modem is also a router.. all configuration takes place on this box.. NONE whatsoever takes place on the TC.
    There is no airport utility 7.7.3 but there is a firmware of that number for the latest AC model TC..
    Is it tall like this.
    Then it is Gen5.
    otherwise it will have a firmware.. 7.6.4 or earlier and the airport utility must be 6.3 or earlier.
    Open the Airport utility and give us a screenshot of the summary page.
    That will also help us determine that you have the TC, which version and how it is setup.
    You might want to press the edit and also give us the Internet and Network tab as they should be set correctly as well.
    I have created a DDNS through DYN.com although I am not sure how to implement this into the TC.
    You do not do anything in the TC.. set it up in the Ubee router.
    Port forward 548 to the TC in the Ubee router.
    And make sure the TC has a static IP in the Ubee router.
    Overall if you find this too hard I strongly recommend you buy a product designed for remote access .. eg WD MyCloud.. they are cheap and easy peasy to setup for remote access.. by PC or Mac and since it is built outside of Apple you not bound up in Apple limitations built into all their equipment to prevent you using it the way you want.. rather than apple want you too.. eg BTMM and iCloud being the only way apple provide for access to the TC and only when it is the main router of the network.
    You are fighting hard because Apple made this hard.. not easy.

  • How do I Set up a LAN with no access to the Internet?

    I have a Solaris 10 (08/07) [No longer can acess the internet]
    full install on one system, and Solaris 10 Developer Edition (09/07) on another system. Each has been auto-configured upon installation, and have reached the Internet, and registered at Sun Microsystems, from behind a router and cable modem.
    I want to create a Local Area Network, using a 4 port Netgear Ethernet Hub, model EN104tp, Each of the Solaris 10 systems, a Windows XP Pro system, and a Windows Media Edition LapTop. +(Which I want to have additional admin control, and access to the Server, from!)+
    My problem is this!
    1) Do I have to change any files to eliminate, the access to the internet from the two Solaris machines via router and cable modem? If so which, and, how do I? +(I intend for the LAN to be isolated from the internet)+
    2) What are the step by step, to set up a LAN?
    I can't seem to find that info anywhere. Maybe I am looking in all the wrong places...
    I appreciate and Thank You in advance for any help...

    The only difference between LAN and Internet is the size.
    Depends on how you define LAN -- it may be multiple subnets glued with routers or just one big or small subnet with bridges, switches and/or hubs or simply a crossed UTP-cable..
    If you don't have routers then you won't need a /etc/defaultrouter (rm -f /etc/defaultrouter; /usr/sbin/route -fn)
    You should use RFC-1918 addresses; i.e. chunks with a suitable mask of your choice as parts or whole of 10./8 (10.0.0.0 - 10.255.255.255), 172.16/12 (172.16.0.0 - 172.31.255.255) and/or 192.168/16 (192.168.0.0 - 192.168.255.255). Example 10.0.0.0/255.255.255.0 for a (256-2=)254-node subnet; 10.20.30.40/255.255.255.252 would suite a crossed-cable subnet perfectly.
    A DHCP-server would be nice for PC's. Solaris can do that (/usr/sadm/admin/bin/dhcpmgr).

  • After upgrading to the latest version of firefox. I can no longer access the internet and all traces of Mozilla Firefox are gone from my computer. I have no access to the internet, my home page or my e mails. What can be done??

    I have been using firefox for years. I downloaded the latest version and at the conclusion of the down load I was refussed access to the internet. Something about Proxy???? I checked my firewalls and security and they said that mozilla was allowed but everytime I attempt to gain access I am refused. I cant access the internet and I cant download another program to access the internet. I uninstalled Firefox and attempted to reinstall but after uninstalling Firefox I have no means to reinstall because there are no traces of it on my computer and I no longer have access to the internet. What do I do? I cant access my e mails, stored messages, favorites etc etc.

    No. After I select "Choose" the dialog box expands to provide only three choices. This is a new bug. I have only seen it in the past week or so, but it is maddening. I have observed that, while the Mozilla Foundation focuses on trivialities like which search engine should be the default, the Firefox application becomes buggier and buggier. Most of my family has switched to Chrome, and I will be following shortly. Firefox used to be a great program. Not any more. Getting assistance with a problem has also become very difficult.

  • C4650 Will only print black from the internet. MS Word and PS will not print in black but has color.

    Before you think I just haven't tried anything, let me run you down with the whole lot:
    -HP PhotoSmart C4650
    -Windows Vista
    -Problem: My printer won't print in black --but-- this only goes for Microsoft applications it seems. If I have a page of text in black, when printing from MS Word, the page comes out blank, however the printer is actually "printing" back and forth. IF, however I print from my browser, from email, or a webpage, picture, google docs, etc, black prints *just fine.* So far this holds true for both MS Word and PhotoShop CS5. Issue: Black ink simply doesn't print from any program other than a browser.
    -NO. The cartridge isn't empty. NO. It's not incompatible. NO. The cartridge head isn't dry and I am not going to soak it in water. This is a new cartridge. It's the official HP brand.
    I've done a search and I've found that a few people seem to have this "only print from the internet" problem, however none of these was solved. The only advice that an HP support member gave to one of them is to "install XP service pack 2" however.. I am not running XP. A few other people get the opposite issue where they can only print color from the internet and not from the computer's applications.
    I don't know much about printers but it sounds like some kind of driver issue. Yes. I've already searched for, uninstalled and reinstalled drivers. Whenever I have to print something, I now try to open it up in my firefox just so I can be able to print black. It's quite the hassle. Almost seems like some kind of ploy to cause people to buy new ink cartridges when it's not really empty.
    -Yes, I have also uninstalled and reinstalled the printer.
    -Updated my windows (although idk how that would help. But I know it's going to be a suggestion anyway.)
    Is there any known fix or should i chuck it off the balcony and go get a lexmark?

  • What is my iPad accessing on the internet when it is charging?

    Hi,
    I have a WiFi only iPad Air which is currently charging. I have noticed that my router is accessing the internet. When I put the iPad in airplane mode the router stops.
    I have confirmed that the following is, as usual, turned off:
    1) iCloud back-up
    2) Auto app updates and auto downloading of iTunes purchases
    3) Backround app refresh
    4) Location services (except for Find My iPad)
    5) iOS is up to date so it is not the update auto downloading
    6) My PC is turned off so it is not syncing via WiFi
    What is the iPad accessing on the internet?
    Any suggestions is greatly appreciated.

    There is a newer version of iTunes than 10.6.3. The newest version is iTunes 11.2.2. It may help if you update iTunes first.
    Has you iPad ever been jailbroken? You can get that error message if the device has been hacked. Have you tried recovery mode.
    If you can't update or restore your iOS device - Apple Support

  • Firefox cut off access to the Internet.

    Firefox cut off access to the Internet.
    In a first time, Firefox completely cut the connection forcing me to restart the Mac OS 10.6.4.
    I restored a version of Firefox antecedent using Time Machine than a month old.
    Now, the connection problem is only partial and Firefox more accesses to the Internet.
    In addition, I must force the software to quit and when I try to restart Firefox, a message tells me that "A copy of Firefox is already open. A single copy of Firefox can be open to both "...?? ?
    You said weird? Someone has an idea on how to solve this?
    Thank you in advance for your help.

  • When you download a movie with your ipad, to play it back to you need access to the internet to play it

    when downloading a movie to your ipad, is there a way to download it, so when you play it back you do not have to have access to the internet?

    If it has been fully downloaded (or synced from your computer's iTunes) then you should be able to watch it in the iPad's Videos app without needing to be online.
    If it's a rental then I've seen some posts saying that you need to be online when starting to play it (which you could whilst you still have internet access, though rentals only last for 24 hours in the US, 48 hours elsewhere, after starting to play them).

    As described above.
    I do not own neither a Mac nor an iOS devices. May I still be able to use all features of Time Capsule, including remote access over the internet?

    You will have setup issues.. as the latest AC model requires a Mac or iOS device.. eventually apple will release a windows version of the utility.. and the current one does partly work but Apple seem in no hurry.
    You can find a Mac or iPad equipped friend to do the setup.. once setup the Windows computer can use it.
    BUTT you cannot access it from remote..
    Not with windows. You need BTMM and iCloud account. AFAIK even with those you cannot reach the TC.
    You can do it manually.. using a vpn. Buy a proper vpn router and use a vpn client on the windows computer.. the TC would be in bridge to the network..
    Apple really did not make this for windows.. and SMB access is only provided on LAN access not WAN.
