    WiFi extremely slow


    I'm on a Toshiba Satellite C870-1HN;
    WiFi adapter: Realtek RTL8723AE Wireless LAN 802.11n PCI-E network interface;
    OS: Windows 8.1 Home;
    Brand new laptop.

    95% of the time I cannot do anything on the network: I can't browse the internet, I can't transfer files between this laptop and another on the network, etc. The task manager network performance indicates 0 kbps sent, 0 kbps received. Occasionally there might be a slight change: sometimes 8 kbps, sometimes as much as 100 kbps. Even then, websites load extremely slow (even in the dial-up era it didn't take 30 minutes to load a website...)

    The other 5% of the time I get download speeds of 2mbps or above. This is very random. I just tried transfering a 10mb file and for the first 20 minutes it did nothing, then it jumped to 1.5mbps, transfered most of the file in 10 seconds, then it got back to 0 kbps and 10 minutes later the remainder of the file got transfered in 1 second.
    Other computers on the network (running windows 7 or below) have no issues at all.

    The signal strength always reads 5/5 bars. Oddly enough, if I disconnect, the network will show up having 3/5 bars. I reconnect again, and I get full signal strength (but 0 kbps). The status is "Connected" (no "Limited Access" or anything, just "Connected")

    The network speed reeds anywhere between 24.0 mbps to 56.0 mbps (and 100 mbps if next to the router)

    Things I've tried:
    - Connected through ethernet (everything works fine, but this is no solution for a mobile laptop)
    - Installed Windows 8.1 (previously windows 8, same issues)
    - The standard windows problem solvers detect no problems with the adapter or the internet connection
    - Set WiFi mode to 802.11 b/g (previously b/g/n) - my router only supports b/g
    - Disabled windows firewall entirely (after trying various exceptions)
    - Disabled IPv6 in the adapter settings
    - Disabled Bluetooth adapter (what the heck, someone suggested it)
    - Disconnecting & reconnecting to the network will often give a spike to 2mbps and then drop to 0 kbps. Sometimes it'll work for a while, but continuously having to reconnect is not a solution.
    - Countless other things that I forgot to mention.

    Pretty much every G router will require a firmware update in order to work "properly" with Windows 8.

    I've already fixed quite a few that way so might work for you as well.

    I have a small Toshiba a NB255-N250 (MK2565GSX) it has a Intel Atom N450 processor, not a power house. I am running Win7 connected to the 2.4gh band of my Netgear AC1900 Night Hawk Router. It loads web pages quickly with no problems. My online youtube videos run without any buffering.
    So I don't feel the problem is with your Toshiba laptop I think it's with your WiFi adapter and wireless Lan.
    I might add your Win8 OS is also not helping matters.

    Both windows update and toshiba updater tell me I'm using the latest version. That said, the linked version is newer so I'll try that tomorrow and see what happens. But frankly, I think it's a shortcoming of Toshiba if they sell windows 8 certified laptops with drivers that don't work...

    As for my router: it's a router+modem in 1, provided by my ISP that also serves digital TV (and forces their own routers on us... damned ISP monopoly). That means I can't use a different router nor can I upgrade the firmware (updates are automatically pushed). It's used by hundreds of thousands of customers here and I can't find anyone with this issue online. I'll try to contact them if upgrading the adapter firmware doesn't work and see what they have to say. Well, I'm assuming they'll say the problem is on my end, even if it's not...

    So I don't feel the problem is with your Toshiba laptop I think it's with your WiFi adapter and wireless Lan.
    That's not particularly helpful, as it's a different model and a different OS. Besides, I'm not using an external adapter, it's internal to the laptop.

    Try running Netalyzr: ICSI Netalyzr it should pinpoint problems. It requires Java, and you need to wait until "Start Analysis>>" appears and click on it. Once the analysis is complete, you submit and view the results. Problems are highlighted in red, warnings in yellow, green OK. You can expand any of the results with a + sign next to them for details.

    With the rest of the computers accessing the router and not having any problems, I figured your router not being an issue. Router makers don't put routers on the market that can't communicate. Windows 8 didn't mysteriously change 802.11 communication protocols either.

    There is a more recently updated driver located here: Version V2010.9.0906.2013 Realtek Wireless Lan Driver and Application 41,26 (MBytes) 2013.10.18 update
    It's listed on Asus' website, but it's the correct driver.

    When I upgraded to 8 and then 8.1 from 7 in one sitting, I experienced driver issues as well and needed to reinstall them to regain functionality. Win8/8.1 does whatever it likes, causing driver malfunctions.

    Now we have a lot more Info. about what your using as the ISP provided hardware. Nothing anyone can do to help with this item. My ISP Cox Cable provides a modem for connecting to the Net and phone service, T.V. is cable direct and has nothing to do with their modem.
    We can use their router or use any router we want.
    As for Toshiba and their drivers for Win8, today we are forced to get Win8 with all new non Apple computers. Microsoft has made so many changes with the 8.1 upgrade, I can understand why many people are having problems.
    Let us know what youre ISP has to say or if they can solve the problem.

    I've already fixed many different connection problems with Windows 8 and 8.1 by doing firmware updates on routers, there were many changes to the network stack which is why new drivers were also required so I'm really at a loss as to why someone would say that updating firmware won't help when it's already fixed countless problems.

    Wireless G routers really aren't worth using with clients running Windows 8, although I'm finding it hard to believe that any ISP would issue a modem/router which is over ten years out of date, probably a Motorola SB something or another which are notorious hunks of junk.

    Those ISP provided modem/routers are junk. At the very least you could try adding another actual "real wireless N router" to test out connectivity.

    You would need to plug them in LAN port to LAN port then disable DHCP on the secondary router, this will allow the first router to provide an IP which is in the same subnet as the first. The first router then becomes the gateway for the network.

    I should also mention that the problems and complaints about this particular wireless NIC Realtek RTL8723AE are countless with similar reports about slow connections and dropping connections although I'm at least partially sure this can be fixed by either updating the drivers and or using the correct firmware on an actual router.

    I learned this by doing research on this particular wireless NIC, I don't guess at this.

    If you'd like an internet argument chev65, take it privately. If you have a real/serious problem directly with me, we can go on any TeamSpeak server and talk about it like real adults. Don't make any assumptions here. You have no idea about me at all. What you do in your personal life, the amount of time you spend on forums, and your total rep points does not give you the right to throw your 7/8Forums weight around and outright call anyone's free advice rubbish, nonsense, very misinformed, bogus, and FUD. That's being abusive and totally against the T.O.S. here... You've been reported.
