Galaxy S4 WiFi problem with Dlink

brochs said:

Hi,

I have been experementing with my SGS4 and my Dlink DIR-655 router (used as access point). I find the problem comes from WPA with AES. Changing settings to TKIP only, and everything works just fine. Only problem is my computer don't get n speed using TKIP. Guess the Dlink is ready for the dustbin now. Have tried several firmwares for the router, all with the same problem. If the fault lays with Dlink or Samsung I don't know, but the S4 is the first to have these problems.

Yeah, have the same issue here. It's annoying cause I have to keep using data plan even after I get home.

I confirm the same problem with a Samsung S4 and a D-LINK DIR-855.
Setting the cypher type to "TKIP" solves it for Samsung but it breaks it for an older Sony laptop.
Luckily DIR-855 is a dual-AP so I could configure the 2.4GHz band with TKIP only while keeping "TKIP+AES" on the 5GHz band.

Samsung should solve the problem. Spent the evening debugging this

Well at least I can stop banging my head on the wall, same problem with a DIR-655. The router keeps locking up, even on a wired connection I can't get anywhere until I turn off the wifi on the GS4.

You can also use the guest zone on your 855 to solve that problem. Then you can keep your 5GHz band on AES+TKIP

Nice. Thanks for the suggestion
I've never used the guest zones but they work well with TKIP albeit at only 54Mbps.
Also enabled routing between zones so I can access other devices on the internal network.
DIR-855 is such a versatile router.

problem but with a motorolla AP300

i also have a wifi connection problem but with a motorolla AP300 running through a RFS4000 enterprise wireless controller.

can connect to other networks with out issue.

this is the error report from the router.

We are on WPA/WPA2-TKIP

have tried changing this and still could not connect.

thank you for this. I have a DLINK ADSL Router and I am having endless issues. I thought it was my router, but now I know its my i9500.

Will a software update resolve this?

Having the same issues -- with Dlink DIR-655

Making some changes mentioned here got everything working well on the phone but obviously ended up slowing down overall performance for other devices (i.e. Apple TV) --- but the idea to use a guest zone (which can also be set to route between zones) --- was a great one, now the phone is working great while still keeping the same performance speeds on the other devices.

May need to get a new router eventually -- hopefully there will be updates to the S4 if that's what's causing the issue, not sure Dlink will release new firmware if it's on their end -- but in the meantime this is a good fix!

Glad I found this thread. I too had the same issue. I didn't think my router was THAT old...

wrong answer

Have dlink 855 myself, for me the solution was to switch router to g mode only for 2,4 range.

I've got a dlink 655, and switching router to g mode only does fix it for me aswell, but turns down speed on all other wireless devices (cause I change it from n mode to g mode - n being the fastest). Is there any way I can have my Galaxy S4 receiving g mode and all my other devices receiving n mode? Don't want to turn down speed on everything just to be able to get wifi on my GS4.......
GS4 doesn't like the dlink's n mode i guess
Never had similar problems with other devices.

When you connect the laptop it "remembers" the settings used, and probably you just need to change from AES to TKIP in the security settings for the WiFi connection. Same happened to my daughter's computer.

Thanks, you're right. I have removed the network and re-added it but TKIP limits it to 54Mbps. My laptop has a 802.11n card. I use the guest AP for S4 and the normal AP with AES and TKIP for the laptop. Everything works well

CIK Telecom and Belkin!! No Connection!

I use "CIK Telecom's" internet and all my devices connect fine to the network (galaxy note 2, s3, MacBooks, HP laptops).

Its just my i9500 that doesn't want to connect at all!! It gets stuck at "Acquiring IP Address".
The message keeps appearing and disappearing every 20-30 secs or so.. I cannot connect at all!!
I use a Belkin router!
I have no idea how to play with the settings on the router itself!

Do you know what do I need to do to get wifi up and running on my s4?? I don't know why every other device works except this one!!!!
The s4 till now isn't working out so well...

I miss my Note 2!!!

Please help... I cannot always use my data plan!!

Thanks in advance!

Tanks

Thanks bro, I have exactly the same problem!!!!!
I was just about to send my S4 for repair. I had no problem with S3

Same problem with Galaxy S4 [i9505] with D-Link DIR-655

Hi,

I have also the same problem, that my Samsung Galaxy S4 has no good connection with my D-Link DIR-655 router. It disconnects
all the time or no connection at all.

With my 'old' HTC One X, I had no problem with connection with D-Link DIR-655.

Strange thing is, that by other people (UPC Horizon Box, TP-Link Router) there is NO problem at all with connection to WiFi with S4.

Frustrating with no connection, I bought a new router from TP Link [TL-WR1043 ND] , and I experience know no problem with my Galaxy S4!

It all seems to be 4.2 issue, not sgs4 specific. Here is Google code thread.
