Q: Slow Wifi on iPhone 6 Plus

Currently having this issue on one of two brand new iPhone 6 Plus's (the other one is fine). Have spoken to Apple Support and it is being escalated to their engineering department - I'll keep you posted on the outcome.

PS I tried all the suggestions in this thread, they were the exact same things that the support guy got me to try as well...

Day 3 with my I6.  I had the problem described above: Consistent Wifi download speeds of around .3 - .4 megs with pings of 17 and upload speeds of 12 megs.  Reset network settings didn't work.  I then experimented with router settings until I put the router in G instead of N and now my download speeds are 13 megs with is the fastest possible with G.

So it's fixed but the solution is not entirely satisfactory because I have a 50 meg Comcast connection and a N router and I'm now throttled down the G.  Which is not terrible but disappointing that a company with the resources of Apple can't fix this.  I hope it's not a bug baked into the silicon.

Please can you advise how I can unsubscribe my email address

from receiving any further updates to the below thread?

 

Thanks.

Hi Champs,

Anybody find the solution. I too have the same problem. Please suggest me how to resolve this?

Is the issue on just one specific WiFi network or have tried more than one in different locations and get the same results?

I bought my iphone 6plus form etisalat (UAE) couple of weeks ago now feel that my phone wifi is very very slow than my old iPhone 4s. now I'm so angry with my phone I've wasted my money to buy this iPhone why this new phone have ******* wifi problem, I dont wanna go etisalat service center.. Because there're *****.They don't even know how service client.I've promissed I would never buy iPhone in future again..I've wasted this time my money to buy this iPhone 6plus.

So, I was experiencing this same problem throughout my house with both my iPhone 6 Plus as well as a few other pieces of hardware.  This might not help everyone, but it made a HUGE difference for me that does not seem to be stopping.

I have an Apple Airport (the new tower design) and had turned on both the 2.4GHz and the 5GHz networks.  After I disabled the 5GHz network, everything seemed to come back to normal for me.  My speeds went from close to 1 meg to well above 20 megs regularly.  I had also had problems getting my older second generation Apple TVs to want to authenticate on the network with both the 2.4 and the 5GHz networks working together, but now have not had a single problem with any of my hardware.  Not sure where the issue is coming from, but this worked for me.  Cheers.

switching from wep to wap2 is what fixed mine

apple send me a replacement for my iphone6 plus wifi problem. 3days working process.

Looks like my solution (work around, really) is to turn off cellular data.   I've tried the WPA2 thing- didn't help, resetting network settings seemed to work for a few days, but then the problem showed up soon after and I lost a bunch of settings that were annoying to redo (all my fingerprints-grrr).  However, when I turned off my cellular data, speeds went immediately back to normal.  I even tested by turning it on and off and it's very consistent for me that with cell data off, my speeds are great.  With it on, my phone is very flaky.
