my wireless internet is extremely slow, (about 1-6 KB/s) but when I connect a network cable, it's normal speed.

A few days ago, I had to do a system restore due to a corrupted program. Once I did the system restore wifi seems to not work at all. The download speed is not faster than a few kb/s but when I connect the laptop to a cable network, internet speed was normal. The wifi on my phone works fine and so did my other laptops.

  • Qosmio F20-155 wireless internet is too slow

    I got another laptop with me that surfing on the net fast but when I use my Qosmio is quite slow?
    Is this something with the settings or all portable Qosmios are the same?
    Help me please!

    Hello

    AFAIK the Qosmio F20 was delivered with the 802. 11 b/g WLan standard.
    Generally, the settings are set to b and g. In this case, you can use both options. But if settings are only to b, so the card only uses this standard.
    The 802. 11 b is slower then 802.11 g
    Speed wise 802. 11 b provides up to 11mpbs gross rate or on 5.5 Mbps after Protocol. 802 11 b is compatible with working with the largest number of installed networks, including all the public hotspots. 802 11 b is also backward compatible with 802.11 products g, because they use all both the frequency of 2.5 ghz ISM band.
    802.11 g has gross rate 54Mbps or about 20mbps throughput after real Protocol or 45mbps overload in turbo mode. If your application involves high speed bypass or copy large files, over 100 MB then 802.11 g is worth watching. Distance wise 802.11 g will only provide the maximum 54 Mbps connection nearby usually less than 100 feet. After this, the connection returns to 802. 11B speeds. Access 802.11 g compatibility points can be set in mode dual b and g taken in charge. There is a problem with this from only a 802. 11B client associates all clients on the network are expelled downwards for 802. 11B speeds. This can be solved by putting in only g mode access point.

    I have an older Dell running Windows Vista, and it started fine when I got it, but about a month ago it started very slow and refusing to open any program.

  • Wireless Internet is very slow on Notebook G7

    I have 4 month old laptop HP-G7-1070us. There adapter without wireless/bluetooth Broadcom 4313 combo. I have never got better

    1.50 MB/s download speed @ speedtest.net. Router is Linksys WRT160N. I get 15 Mbps speed of downloading if I boot to Linux Mint using the USB. The router firmware has been upgraded to version 2.11. My Toshiba A205 Satellite card AR5007 and gets to Win Vista 19.50 MB/s download speed sitting next to my provider Internet HP. is Comcast Cable ethernet adapter works fine. I tried 4 months for this work because I like the challenge, but now I need help. I think there must be a Windows 7 configuration problem. A 695 MB file takes 12 hours to download but 12 minutes on Linux and on Toshiba and is unusable in the video streaming in the windows.

    Thanks for any help.

    I have reset the mode on my router to stream 'G' rather than 'mixed' mode only This solved my problem.

    He also cleared up the terrible problem buffering, that I got with my blackberry cellphone that uses my home network.

    I can now achieve 18 + Mbps download speed according to www.sppedtest.net.

  • EXTREME slowing windows 7 professional 64-bit response time, possibly problem driver network adapter? Help, please!

    I have Windows 7 Professional 64 bit installed on a computer, I built

    Data sheet:
    Processor Intel i5 750 (stock clocked & stock cooler)
    Card mother Gigabyte GA-P55A-UD3P
    G. Skill Rip jaw DDR3 1333 RAM (standard timings)
    Western Digital 640 GB SATA HD
    Card EVGA 8800 GS SC Video
    Creative Sound Blaster Audigy SE sound card
    Powersupply Coairsair 650W
    Samsung SATA DVD writer

    My problem is, after I started and had my computer running for a significant amount of time (30 minutes to an hour), I loose full internet connectivity and the response time for any action I'm trying of the preform is from 30 seconds to 5 minutes.

    This problem occurs almost every time my computer is started for a significant amount of time, and it's extremely annoying.

    First Firefox, Google chrome, or internet Explorer stops receivers internet connectivity (because it is not sailing to any web page) but still related reports.

    (during this time and on my computer don't report any anomaly, IE CPU utilization / ram uses / temperature are amounts all acceptable)

    I usually try to close my browser (s) web, but its reports "not responding" and I cannot close or even end the process or the process tree, so it runs as a process. From there a program or a click I do I try to run either doesn't work or takes 30 seconds to 5 minutes to register if they register at all.

    Programs I all ready have running continue to run, IE Vuze, WindowsMP, Zune software, openoffice. But once that I close them I can't reopen.

    Any program I try to open starts a process in the Task Manager but it not to start a program or actually run, and I can't used to finish the tasks that do not work properly.

    If I try to shut down windows, it takes a minute or so to begin to disconnect, then he sits on the "logging" off the screen until I use the power switch to kill the system.

    I suspect that it may be a problem from my network card driver (Controller Realtek PCIe GBE Family, latest version downloaded directly from the Gigabyte website for my motherboard) because the question almost always starts when my internet stops working. However, this may be 2 combined numbers.

    I had this problem and I thought it was because of an installation of bad windows 7 so I erased the hard drive and did a complete new installation, but the problem is back!

    I changed my routers settings to give me a fixed IP address to dismiss questions here. All the other computers in my House have access the internet without interruption during my problems. And no other computer in my house has similar problems.

    I reinstalled the network once drivers without success.

    I would like to address the downturn extreme Windows 7 after half an hour or so if possible because I have other NICs lying there if the problem comes from the network card.

    I'm pretty computer savvy and I've exhausted all my ideas, so any notice are useful! Thank you

    OK, so I think that the slow issue is resolved now. I blame intel speedstep, while part of my problem is fixed.

    Internet connection problems still remain.

    I ran my computer in safe mode with network for about 2 hours. When I booted in safe mode, everything was fine, internet connetion worked on download and upload at full power. I let it sit for an hour or two in safe mode and I came back and there is no internet again, as usual. All my browsers (internet explorer, my main browser firefox and chrome) refuse to function / load anything and their work will not end in the Task Manager. The device says it all works and it (network adapter) said I have a connection, but I am squatting me on my browsers or any other uses of the Internet. This test will run on a network interface card that I installed, with drivers. I did him wrong with shooting my motherboard cable network and its software driver port. This new card gives the same result, so I think now I know that this issue has nothing to do with my physical port or its drivers.

    The only things I can think that it either now are either:
    my router
    However, all the other computers in my house (3 of them, 1 win XP), 1 Win 7 64 bit pro, 1 Ubuntu and my Xbox 360 not having this problem and works perfectly

    or

    Something inside windows 7 that control the browsers or manages connections,
    I think it's most likely due to the fact that my browsers have problems in the Task Manager / they do not work properly

    All reviews are useful,

    Thank you!

  • Download of virtual machine using extremely slow browser data store

    Hello

    Why download VM files totalling nearly only 8 GB in vSphere Client v4.1.0 (from 4.1.0 ESXi) via a Gigabit LAN would take more than 1800 minutes (30 hours)? Well now after about 5-10 minutes to download, it is said 1560 minutes but still, why is it so slow? I thought that perhaps is that the estimated time remaining is miscalculated, but this isn't the case. The download is just extremely slow.

    Not only that but vSphere Client (VpxClient.exe) constantly uses 25-45% of my cycles while all CPU's do the downloading of files. This slows down the PC I am running vSphere Client. The local network on the server and the client connections are Gigabit too.

    UPDATE: download time now has increased up to 1924 minutes back and it becomes difficult to use my PC for e-mail in Outlook, etc. because vSphere Client seems to use as many cycles CPU.

    UPDATE 2: 2 hours for download via vSphere Client and remaining time jumped up to 2287 minutes. I'm going to cancel and try to download via the web browser interface.

    See the attached screenshots.

    Thank you

  • Satellite U-305 wireless Internet connects at 54 Mbps, then freezes

    Using wifi internal adapter Express Card or a USB wifi adapter I can connect to the internet, but when the initial page download bar reached to halfway it grinds a setback.

    The pressure gauge shows a five bar connection to 54 Mbit/s on the whole.

    When I connect with a cable, I get 100 Mbps and full, quick internet access.

    This occurs with Firefox, Internet Explorer or AOL.

    This happened all the time that I had this computer.

    The wifi on my other wireless, T Palm device. X, works perfectly.

  • Time Machine extremely slow after upgrade to El Cap

    Time Machine problem with upgrade to Yosemite to El Cap on a laptop MBPr 15 "mid-2012.

    Time Machine backup plan: by wifi or LAN cable for two different hard disks attached to a Mac Mini that is on the local network. Two USB mini drives would serve as a backup for a total of 4 Mac disks at home.

    Behavior of Time Machine in Yosemite: dead normal. Backups were fast (10 Mbit/s in wifi, 80 MB/s when I plugged the MBPr on my LAN using a bolt of lightning for the Ethernet card.) Restored backups (I test them sometimes) fine.

    I upgraded yesterday to El Capitan. Behavior of the time Machine now: excruciatingly slow. All the steps (preparation, backup, cleanup) takes hours. My laptop was connected to the wired LAN for 9 hours now and is only 1.26 GB thanks to a backup of 3.82 GB. Speed (from MenuMeters) is under 10 KB/sec - Yes, it is * kilogram * bytes/s.

    Speed of transfer of files between the two machines via drag & drop is very good, ~80MB/sec both on the LAN, about 12 MB/s in wifi. Laptop computer interacts with the web at normal speeds. It does not appear that Time Machine, which is watered, and only on my laptop of Capitaned newly-El. My other domestic machines (all on Yosemite still) back up normally.

    I tried:

    -power / reboot both machines.

    -power / restart the LAN together.

    -cycle Time Machine power switch in the Prefs system.

    -Remove the two drives as backup targets TM laptop, then re - specify with preferences TM;

    -other things that I found through the search for this problem.

    It is a common problem in judging by the many valuation model who met it. I searched a lot and found nothing that helped me.

    I can't work without a viable backup. For now, I use Carbon Copy Cloner to duplicate my SSD MBPr for an external hard drive. Not really satisfying.

    Did someone solved this problem? Can someone tell me or suggest a solution? Thank you very much!

    Please make a copy of test in the Finder of the source for the backup volume. Is it too slow? Delete the files copied from the backup volume after the test.
