samsung galaxy s4, D-Link routers, wifi issues solved!

Latest Firmware revision download and install solved the Galaxy S4 problems for me.
I could not stay connected long enough to download a 100 mB map file at 6 mbps, until I upgraded my A1 version 1.00 firmware on my D-Link 825 router.

Success! Very nice.

Thanks so much for the tip.

I am a daily traveller at the London underground and the phone has massive problems in connecting to the wifi network under ground as well asin my own home as well as other homes.
I can not change anything on the underground as it is the property of London Underground.

I have three phones, S2, S3 and S4. The S4 works bad on all Wifi networks while the others are brilliant.
I have the same problems on a BT (Brittish Telecom) as well as on a Virgin Media router as on a DLink router.
 
hey, I was having same problem, I changed my 802.11 band from 2.4 Ghz to 5Ghz and the problem was solved, hope it works for you. Look for your wireless settings.
 
Hi, I've a D-link dir 655 firmware 1.31EU, 2010/01/14, and had similar kind of wifi connection problems with my new samsung galaxy s4 active as jim 1745 reports. I can also confirm that by switching the wifi router cipher protocol from "tkip and aes" to "tkip" my connection problems went away. fyi I run wpa mode "Auto (WPA or WPA2)", security mode "WPA personal", auto channel scan, transmission rate "best" and 802.11 mode "Mixed (n + g +b)".
 
Ditto -- lots of issues with my DLINK DIR-655 (version A2 running 1.35NA firmware) for the last 2 weeks -- started exactly when I brought my beautiful new Verizon S4 home.

Today I notice a firmware upgrade to 1.37 on DLINK's web page which states "Improved compatibility issue with Samsung Galaxy S4". It is dated 6/11/13. I just installed it and hopefully it works. Everyone in the house is frustrated as my router keeps freezing for everyone.....

D-Link | DIR-655 Wireless N Gigabit Router

I can confirm as well that this firmware resolved the issue.
 
Hello guys,

I had the exact same problem with my Samsung Galaxy S4 and DIR-655 (A4 revision, 1.32 firmware). Installing the latest firmware 1.37 completely fixed the issue. The release notes for this firmware version (released in 6/11/2013) says "Improved compatibility issue with Samsung Galaxy S4". I knew my problem was solved when I saw that statement.

You can find the firmware download from dlink's site using the following steps. First connect your laptop using an Ethernet cable to your router. I read somewhere that it is better to have a wired connection while updating the firmware. Maybe you really don't need it. I don't know; I used a wired connection for this operation. Then, simply type DIR-655 in Google, choose the first link which has to be dlink.com. In the middle of the page, there is a "Downloads" tab. Click that and then click the link "Go to the DIR-655 support page". Then type "DIR-655" (without quotes) in the search box that appears. The search results should list DIR-655 Xtreme N Wireless Router. Choose that. Then from the drop-down for the hardware revision, choose "A" (or whatever is correct for *your* modem; the revision number and firmware number is at the back of the router). Finally, you are presented with the download for the firmware (make sure it lists 1.37 or more). Hitting the download button downloads it as a .zip file. Unzip it to extract the lone .bin file inside it. Then go to the router's admin page (it is 192.168.0.1 unless you have changed it). Log in using admin password (it is empty unless you have set it). Then click the "Tools" tab. Then the "Firmware" tab. You should see buttons to choose a file on disk and to actually upload it to the router for installation. Pretty straight forward from here. BUT WAIT!!!!. Uploading this firware version wipes all your existing settings. Which meant that I had to reset the Wifi password again, etc. If you reset it to the same password it was before the wipe, you don't have to re-enter a new password into all your mobile device in your home. This was a minor hassle compared to the joy of getting my router back in action. One more thing, on the Firmware page that allows you to upload the .bin file, there is a "Check Now" button. I assumed it would smart to actually detect that my firmware was old and download the new one. But no such luck. It just said that the firmware was up to date. Liar! Just use the manual upload path explained above.

I owe a thanks to this forum for fixing my problem. Hopefully, my detailed notes help others. Best of luck!
 
Just posting a possible fix for anyone having related issues.

I had problems connecting my S4 to internet through my dlink DIR-655. It connects to the wifi, but no internet.
None of the fixes suggested like updating firmware, changing to TKIP etc worked for me.

I tried to change different settings on the router and on the phone and suddenly I noticed on the S4 it had an IP-address outside the range of the router.

Solution:
On your router:
1. Log in to the router. Note the LAN IP address of the router (Mine was dlink default 192.168.0.1)
2. Note the DHCP IP range on your router. (On my dlink was is found under Setup/Network settings, and the settings were default: 192.168.0.100 to 192.168.0.199)
On your Samsung
3. Go to settings/connections/wifi (click the icon, not the on/off switch)
4. In the list of networks, click and hold the name of your wifi to see the menu. Choose "Change Configuration".
5. Change IP-settings from DHCP to Static.
6. Change your IP-address to one in the range as described in 2. (I set mine to 192.168.0.199 which is the last in the series, to avoid conflicts with other users that might have gotten one of the first IP-adresses)
7. Change Gateway to your router's IP as described in 1. (Mine was dlink default 192.168.0.1)

Hope this helps someone. It took me several hours to figure this out.
 
I would also like to share what worked for me.
Initially Samsung S7 Edge wouldn't connect to Wi-Fi via D-link DIR-320 router: it detected the network, but made no attempts to connect, or when forced to connect manually, nothing happened. A dozen other devices in the household were working with this router seamelessly.
Updating firmware to the latest official version, or using alternative versions DID NOT work.

After experimenting with settings a bit, I discovered that these ones worked!
Particularly, changing WPA2 to WPA-Auto-Personal, and TKIP + AES to TKIP.

Hope this saves someone the hours I spent in frustration, Google, and trial & error :)
