    Update – Please read my comment below this post which describes further essential information. The procedure described here can still be followed, as it DID improve my connection considerably.

    I have a faster WiFi connection at my home than at work, yet my Android phone would be painfully slow at opening pages in the browser.
    I solved this by setting my router’s
    1) MAC filtering
    2) Change DHCP settings in router, to Google DNS or OpenDNS
    3) Match static IP in Android device
    UPDATE – Switch your router to send ONLY 802.11G signals – If you have a more advanced router, you should also have 802.11N option which is much faster, but Do make sure that your device is compatible with 802.11N wi-fi. Also, select an uncrowded channel and set your router to use that channel.

    Find your gateway address by checking your network manager. Enter that into your PC browser using a WIRED connection. My router configuration pane is at this address http://192.168.123.254/
    Log in using your user defined password or the manufacturer’s default password (usually the default password is “admin”).

    Check a previous blog post for some help with securing your wireless network
    Secure your wireless network/WAN, no one else will

    1. Wireless Router – Configure MAC fIltering

    Find the “MAC Filtering” configuration pane and do the following
    Check/Enable MAC filtering
    Check “Association Control” and drop down to “enable or allow”
    Enter your phone MAC Address in one of the blank slots
    (MAC address can be found in Android 2.1 by going to Menu > Wireless & networks > Wi-Fi settings Menu > Advanced)
    My connection uses DHCP, so I found the range of legitimate IP addresses for example from 192.123.456.100 to 199
    In my MAC filtering pane, I can generate a static IP by dropping down a menu – my android MAC address had been stored in there, so it made it easier for me.
    You need to enter the last 3 digits (a legitimate IP address from the range obtained from your router)
    Check the “Association Control” box to the right of that slot.

    2. Wireless router – DNS
    This step is optional
    Find DHCP settings and go to the advanced settings – to assign DNS
    You can use Google’s servers 8.8.8.8 and 8.8.4.4 or OpenDNS servers 208.67.222.222 and 208.67.220.220

    Save your new configuration and turn the wireless router off then back on again.

    Log in again and now find essential data from the System Status pane of your router.

    3. Android Device – Static IP configuration (to a DHCP internet connection via a wireless router)
    In your android phone, go ‘Menu > Wireless & networks > Wi-Fi settings Menu > Advanced’

    Check “Use Static IP”
    IP Address – enter the IP you assigned in the MAC filtering slot of your router
    Gateway – enter the IP address you entered in your PC browser to access your router’s configuration
    Netmask – enter the subnet mask you find in the status pane of your router’s configuration System Status
    DNS 1 enter the first DNS address from your router’s configuration System Status or if you changed these servers, then enter the DNS server you entered previously
    DNS 2 enter the second DNS address from your router’s configuration System Status or if you changed these servers, then enter the DNS server you entered previously

    Useful additional apps from the Android Market:
    IP Manager or Wifi Static are two useful apps in the Market to conveniently store and switch between more than one static IP configuration (Android OS currently only makes provision for one static configuration).

    I’m finding my android browser handles pages faster after doing this.
    Please give me any advice or share your own experiences.
    This is pretty much a trial and error process, so I’m all ears.

    NOTE: You will need to assign any other devices/by MAC address, to individual ‘static IP’ addresses in the same way. Choose ‘DHCP with Manually assigned IP’ on Mac or Linux

    Excellent detailed advice as well as a few more apps that might be used to trouble-shoot, at SearchNetworking.au.com “How to fix Android Wi-Fi problems

    Secure your wireless network/WAN, no one else will 

    I noticed some naughty young hacker looking boys in the park next to my home which got me thinking how INsecure my personal wireless network was… Stock-standard SSID: unicorn, Security: None, Router setup password: admin. Not Good!

    There are various lists and services to discover your own broadband router manufacturer’s default IP and password. You can google those but after many failed searches I followed my intuition and checked my unsecured Wi-Fi network Default Route IP in my network connection pane and entered THAT into my browser.. BINGO!

    This link here was useful, and I entered the password “admin”.

    I followed those steps in that link:

    Important note! Connect using a wired LAN to setup your router.

    On my router’s setup page, I chose “preferences” then found my way with some trial and error (made difficult because my router’s setup UI is in Korean – used chrome to translate it)
    1. Changed my password from admin to “mypassword”
    2. Changed my SSID to “mine”
    3. Selected WEP 40/128-bit key

    4. Entered four unique 26 character Hexadecimal keys on that router admin page..
    Allowed characters are “0-9” and “a-f” eg. 123456789abcdef10237689546
    Saved these keys to a file on my computer. I also made a backup as a draft in my email (perhaps not wise, but knowing myself and paswword.. 🙂 eg.
    WEP Key 1 = 123456789abcdef10237689546
    WEP Key 2 = 123456789abcdef10237687896
    WEP Key 3 = 1234abcdef123def1023768956
    WEP Key 4 = 123456789abcdeab123456d546

    It took some guesswork but eventually I got a notice saying something about “Reboot”. So I turned off my router box and rebooted my laptop. Unplugged the wired connection to the internet and waited to discover my wifi. It was now renamed and secured.

    Now all I needed to do was setup my network. My laptop is running Ubuntu (Karmic Koala) but I am certain these procedures are very easy to perform on Mandriva.

    Select WEP 40/128-bit key
    And toggle to Authentication: Shared Key
    Drop down to WEP index: 1 and enter WEP Key 1 from my records file
    and hit apply.
    I did the same routine for WEP Index 2-4 entering the corresponding keys from my file record.

    My wireless network is now encrypted with WEP. I have heard that WPA encryption is more solid, but I can’t be too bothered. WEP is better than nil. Good luck and have fun blocking those would be hackers out there.

    *Update:
    I have now encrypted using WPA2-PSK(AES)
    at Step 3 above, select WPA2-PSK(AES) then ASCII and enter a single password
    A good password contains a mix of upper and lower case characters, letter and numbers. You can also include punctuation characters. To be quite honest, I was surprised at how simple WPA security setup is. So there. Life is easier than we expect sometimes. With my setup, I only have one key which all devices will share, unlike WEP keys which different users can each have a special key. One user can have a key revoked as well, giving the admin of a network some level of control which is lacking with my current setup.
