• bluetooth doesn't recognize mouse (and other devices)... sometimes

  - by Angelo

  I have a problem with bluetooth with Vista, running on my MacBook. It often doesn't recognize my wireless Magic Mouse. And I saw that it even doesn't seem to start as the pictogram in the task-bar isn't there most of the time I run Vista. But I'm only an Apple-nerd, so I don't know to much about this issue on Vista. When reinstalling Boothcamp or other updates, then once in a while bluetooth recognizes my own mouse (and other devices from some neighbours... so that implicates that the problem must be the bluetooth function in the first place, not my mouse.) Is there some update for the bluetooth application? Angelo

• Why would my mouse pointer be jerky when it can't get a signal from my router?

  - by izb

  I've got a fairly new PC but when moving the mouse across the screen, the pointer jerks as if the PC is freezing momentarily every second or so. Strangely, this only seems to happen if the signal from the wifi router is bad. If I move the PC closer to the router to get a full signal, it's fine. It also seems to affect the keyboard; Opening notepad and holding down a key shows the same momentary freezes. -- Update: It's a logitech wireless mouse, and a wired USB logitech keyboard.

• How to troubleshoot ping request time out [closed]

  - by user28317

  I have a Windows 7 and an XP machine connected to a NETGEAR wireless router. Both machines can log into the network and surf the web. Both are connecting wirelessly. I can ping the router from each machine and get a reply. I can ping each machine from the router and get a reply. But i cannot ping each machine from the other; getting a request time out. Subnet IP Addresses are 192.168.1.* Router =1; Win7 = 10; XP = 11; Firewall is currently off in both systems. Since i can ping from router im picking that not the problem anyway. If i try to ping from xp to win7 i get Request Timed Out. If i try to ping from Win7 to Xp i get destination host unreachable. What should i do now? Thanks

• Mountain Lion screen crashes after returning from sleep

  - by Aron Rotteveel

  During the past 3 days I have experienced the following issue: when returning from sleep, I see an extremely garbled version of my desktop. The only thing that seems to help is a reboot. My first guess is that this is related to the video card. After looking into this issue, I found a lot of problems related to ML and returning from sleep, such as this post on AskDifferent, but I think this is a different issue because it does not speak of a garbled screen. Some more details: System: MacBook Pro 15" early 2011, 2,2GHZ I7, 8GB Ram, AMD Radeon HD6750M 1024 The issue seems to happen only when I open my laptop in the morning; if I close and open my laptop during the day, it does not seem to happen. The issue 'solves' when rebooting. Photo of how this looks: Update November 27th 2012: I re-installed my laptop a couple of weeks ago, which seemed to have solved the problem, but sadly, it still persists.

• Windows 7 Default Gateway problem

  - by Matt

  I have a strange problem (or at least seems strange to me) the below are IP configurations for two laptops on my home network which consists of a main router 192.168.11.1 and a connected wireless router (i know this can cause problems but has always worked until I got the win7 machine) at 192.168.11.2 with DHCP disabled. Laptop 1 - Win XP IP: Dynamically assigned by main router default gateway: 192.168.11.1 (main router) This machine gets perfect connectivity. Laptop 2 - Win7 IP: dynamically assigned by main router Default Gateway: 192.168.11.2 THIS IS THE PROBLEM... I cannot seem to get this machine to default to the main router for the gateway UNLESS I go to a static configuration which I would rather not do since I regularly go between my home and public networks. Why is my Win7 machine not finding the main gateway the same way that the other laptop is? I believe that the rest of my setup is fine as it has always worked and it works perfectly when set as static ip and gateway. Please help! Thanks

• How do I get a 300Mbps connection over 802.11n?

  - by Daniel Schaffer

  I just bought a new wireless setup, consisting of a Cisco E2000 router, Edimax 7718un USB adapter for my laptop and an Edimax 7728in PCI adapter for my HTPC (which isn't in a location I can run cat5 to). I have to stay in the 2.4GHz band because I have an iPhone and a Wii that will need to connect. I'm aware that 11g devices will drop speeds for 11n devices, but they aren't connected yet. The fastest connection I've been able to get, with the router within 5 feet of either the laptop or HTPC is 144Mbps. The router has settings for "20MHz" and "Auto (20 MHz or 40Mhz) channel width, which I've set to the "Auto" setting. I haven't been able to find anything similar for either of the Edimax adapters. This is the first I've dealt with 11n, so I'm not even sure what else could be causing a problem. How do I get up to 300Mbps, or at least a fair bit closer?

• Multiple monitors on ATI Radeon HD 5450 1GB DDR2 (Brand: Sapphire)

  - by Robert

  From other posts here, I understand that it might be possible to use up to 3 monitors on this card. My understanding (from the other posts here as well) is that since I have a HDMI output, I do not have a 'DisplayPort', right ? Mine has indeed 3 ports: DVI, HDMI and VGA. Can I have dual-monitor using both the HDMI and DVI ports simulataneously (I am not looking for Eyefinity, but simply extended desktop). Currently I am using dual monitor with DVI and VGA but will replace my 17 inches next week with a new (larger) one that has both VGA and DVI, so I intend to use both monitors connected digitally. I intend to purchase a cable ''HDMI to DVI''(MM) to do so on the second monitor. Optimal resolution on the one I intend to keep (22 inches) : 1680 x 1050, primary monitor. New one (24 inches) has an optimal resolution of 1920 x 1080. Am I running for problems ? Thanks, Rob

• Can't ping IPs for devices not part of Windows Domain

  - by GiddyUpHorsey

  I have a home network with a Trendnet wireless router and a Windows Domain. The DNS server is on a Windows 2000 Server and is configured to forward queries to DNS servers provided by the ISP. The router provides DHCP and is configured with the Windows 2000 Server as the DNS server. When I connect iPhones to the network over WiFi, the router can ping the iPhones through its browser based admin interface, but Windows machines that are part of the Windows Domain cannot. A laptop was connected to the network over WiFi that wasn't joined to the domain and it could see the iPhones. All machines either have a fixed or DHCP allocated IP on the 192.168.0.* subnet. How do I configure the DNS server or the Windows Domain so that Windows machines can see the iPhones?

• Logitech MX3200 keyboard stopped working

  - by Roy Rico

  I have a Logitech MX3200 wireless keyboard and mouse set, and keyboard stopped working. I was working with it and it just stopped in the middle of using it. Some notes: The mouse still works flawlessly, i've tried to reconnect the KB i've tried to reconnect everything, mouse reconnects, keyboard reconnects (or pretends to) I've tried to hard reset (holding the connect button on the receiver for 10 seconds). I've tried new batteries I took out the batteries out of the KB & Mouse and unplugged the receiver over night. The media keys still work (launches winamp) but they main keys does not At this point, i've tried everything I've seen online. I just want to know is my keyboard dead in the water? I would say it's been about 8 months to a year since i've bought it, and the articles i find on the internet all say that's as long as they last... is this true? what's everyone's experience? I hope it's not true.

• Is it possible to sync specific router settings across multiple routers?

  - by Betard Fooser

  I recently purchased a second Linksys wireless routers set up on the other side of my home and I am wondering if it is possible to somehow sync particular settings between the two? For instance what I am really after is the "MAC Filter List". I would "like" to be able to maintain the list on both routers without having to manually type in the field values. maybe this isn't possible, or has an easy answer, but hopefully those of you who know will cut me a bit of slack. I tried to "google" the answer to this of course, but it seems any searches with the words "sync" and "router" and/or "wifi" result in pages of people having issues with synching their iOS devices over wifi. I would say that have decent amount of networking knowledge in regards to average home networks, and I imagine in larger businesses / corporations they must have a "simpler" way of maintaining things like this. Any insight to point me in the right direction will be much appreciated.

• Multiple WAPs: Bandwidth, Frequency Considerations

  - by Pete Cresswell

  The router in my LAN closet does 2 and 5 GHz. In the kitchen, I have a single-band 2 GHz WAP, and in the garden shed I have another single-band 2 GHz WAP. All are set to Bandwidth = 40 MHz, Wireless Network Mode = N-Only. The kitchen WAP and the LAN closet router both come up with multiple bars on my smart phone from almost anywhere in the house. The garden shed WAP will register one bar... but only sometimes. The Questions: Are these things in danger of butting heads? Should I re-set them to Bandwidth = 20 MHz? Bandwidth = Auto? Are there any tools that I could use on an Android smart phone, iPod, or WiFi-enabled laptop to make my own analysis?

• No Drivers in Ubuntu 9.1!!!

  - by Chris

  I have a Lenovo G550 and I installed Ubuntu on it through Windows and I have no drivers. No sound, no wireless. I previously had installed it through Windows Vista with no problems at all. I now run Windows 7 and cannot seem to get it to function properly. I tried installing the recommended drivers to make sure the proper ones were installed and that still did nothing. Any one have ANY idea what could be happening? I just don't feel like dealing with it.

• DVI-D Splitter Not Working with GeForce 8400gs

  - by jimdrang

  I have a GeForce 8400gs and it has a DVI and VGA port on the back. I was using dual monitors with one VGA and one DVI cable. I wanted both displays to be digital so I bought a DVI-D splitter and put one DVI cable in each monitor, connected them to the splitter and put the single merged connection in the back of the cards DVI connection. It will not recognize the second monitor (I'm not even sure how it determined which one was the first monitor). The tech specs state that it supports "Two dual-link DVI outputs for digital flat panel display resolutions up to 2560x1600" http://www.nvidia.com/object/geforce_8400_tech_specs.html. Do I need a different converter or is my only option for dual monitors with this card one VGA, one DVI?

• Is it possible to use two separate USB tuners with Windows Media Center?

  - by Lunatik

  I'm planning to replace my traditional PC-style media center (with twin tuners) with an Asrock Ion 3D (or similar) but this means forgoing my existing PCI-E dual tuner card for a USB solution. Since Freeview HD (using DVB-T2) is now available I'd like to equip my media center to take advantage. The trouble is there are currently no dual DVB-T2 USB tuners on the market (that I can find anyway). Would I be able to plug two separate USB tuners and have them correctly picked up and working within all apps, including Windows Media Center? Are there any caveats I might need to bear in mind when using two tuners in this way?

• CoovaAP router does not get DHCP settings from modem

  - by Dan Sosedoff

  Im having some serious trouble making CoovaAP-powered router get network settings from modem. Wireless router works in captive portal mode (so it handles user login on the same device). But DNS settings and connection ip (for router) are not set as they supposed to via DHCP on modem. It makes installation in other location really complicated, because you have to go and set everything manually. For now i use google`s dns servers. What`s the way to make router self-configurable via modem's dhcp ?

• Why do some devices seemingly need the wifi router to reboot before they can connect?

  - by CreeDorofl

  I've noticed a pattern but I'm not sure if it's a crappy router, crappy wireless device, or maybe everything is working as intended. I can wirelessly connect my office PC to the router's settings page for a day, maybe two, then afterwards I can't anymore until it's reset. Unrelated, but similar, in various places that offer free wifi, my kindle will connect fine most days, but occasionally won't unless the router is reset. After the reset, I connect ok. What's happening behind the scenes that makes a router stop allowing you to connect? Is it something on my end that's changing, or on the router's end?

How to make the laptop directly connects to the Internet after booting without switching the cord?

• PCs with Wired Connection Keep Losing Internet Connectivity

  - by user717452

  I have a U-verse ATT DSL Internet at our church building. Recently, any computer that is plugged into the network via Ethernet keeps losing its internet connectivity. The setup is from the Modem to a Netgear Wireless Router, and from the router to 3 different computers. None of the laptops that use Wifi ever lose internet, just the wired ones, and I end up having to do ipconfig /release and /renew every day to get it back. One computer has Windows 7 and one has Windows XP. Any ideas as to what is going on with our network?

• DisplayPort to DVI not working on Quadro FX 580

  - by kaosvid

  I have a PNY NVIDIA Quadro FX 580 graphics card with 1x DVI and 2x DisplayPorts. The DVI port works fine with both my Viewsonic monitors but I cannot get either of the DPs to work using the supplied DP to DVI adapter; all I get is a "no signal" on either monitor when connected to either DP port. The NVIDIA Control Panel shows that the second monitor is not connected when in fact it is. How do I get the second monitor to work?

• Connecting desktop computer to the internet through laptop wifi

  - by Josh

  Due to some home network complications I have had to move my router to a seperate part of the house, therefore the wired network I had set up can no longer work. Before I find the time to go out and buy a Wifi adapter for my desktop PC, I have a laptop that uses a built in Wifi card to connect to my router and this can connect to the internet, and I was wondering if I could somehow access the internet on my desktop PC via my laptop. I'm hoping for a not-so-complex solution as this will only be set up for a few days, but it is quite vital that my desktop computer gets internet access. Does anyone have experience in this sort of thing and can help me out? Thanks.

• Extremely poor WiFi reception on new desktop

  - by guy

  I just received a new desktop with a built-in WiFi card (Windows 7 Home Premium x64). However, I am only able to receive any WiFi signal when the computer is within 1-2 meters of a router. Even then, the signal is very weak (Windows 7 says it is "poor"). I have tried this with 2 different routers and see similar results. I have somewhere around a dozen other devices that can connect to both routers with greater signal strength (usually full strength) from much, much further away. When I tried calling support I was instructed to reinstall my drivers and attempt to change the WiFi channel of the router. Neither worked. I was then told that the problem was with my routers and that the computer was functioning normally and that it was certainly not a hardware problem. What would be the cause of this and is there anything I can do to fix it?

• Dns works, can ping, but cannot load web pages in browser

  - by user1224595

  Yesterday I changed routers, and my desktop computer started acting up. I could ping websites, and nslookup was able to resolve names to addresses, but neither chrome, firefox, nor ie could load any webpages. None of my other computers connected to the same wireless router have any problems. I connect my desktop to the router through a cheap wifi dongle. I did a wireshark capture of the browser request, and I have uploaded the pcap here. https://drive.google.com/file/d/0B7AsPdhWc-SwbTV0bUJLQXo4UUE/edit?usp=sharing One strange thing I noticed was the spamming of ssdp packets. I am not super familiar with networking, but it seems that it is not a problem with the router, as dns works, and so does dhcp (the desktop is assigned an address correctly). Any help would be appreciated.
