Re: iPhone router saturation

GMAK · ‎2016-01-21

Environment:

WNDR4000 - V1.0.2.4_9.1.86
iPhone 6S - ????

I need some brief validation please. My wife's iPhone is saturating my router. I have looked for similar issues,
but can find nothing like. She connects the phone at night for its charging cycle. Unfortunately, I know very little
about these phones, but apparently, in addition to charging, the phone undergos some kind of data synchronization
for cloud backup purposes.

When this process get rolling, it will absolutely smoke this router. To the extent that simply initiating a web access
can be a 2-5 minute erratic operation. Of course, we've come to mortal combat over this issue. But I request a
validation of changes I've made, to ensure a proper circumvention.

Briefly, I changed the router configuration to enable QoS, and changed the iPhone traffic priority to low. I am test-
ing it now as this is written, and it seems to have dropped the phone traffic considerably. In fact, as I'm watching
the router activity, I see only very intermittent activity.

The previous iPhone(a 4S, as I recall), seemed to do this synchronization during charge, but didn't clog the net-
work nearly like this 6S does. I've been enduring this issue for at least a year, and just to busy/lazy to dig into
the problem.

Does my circumvention sound accurate, and will I(she) encounter other unintended problems with the phone
operation during network use?

Thanks.

After not being able to find anything important in research of iphone backup

settings, I did find this which describes my problem exactly

http://hardforum.com/showthread.php?t=1737872

My QoS recent change was not quite as fulfilling tonight as the last in the

last few nights. I thought the QoS tweak had corrected the bandwidth

problem. But, tonight's backup reared the saturation again. However it

didn't seem quite as bad, and for a shorter duration.

So I think the network saturation has been retarded, bu is still present,

although to a lessor degree.

You never mentioned your UP load speed. What is it?

1.

Download Speed 5.13 Mbps (641.6 KB/sec transfer rate)
Upload Speed 0.69 Mbps (86.6 KB/sec transfer rate)
Latency 43 ms
Jitter 1 ms

2.

Download Speed 5.14 Mbps (642.1 KB/sec transfer rate)
Upload Speed 0.69 Mbps (86 KB/sec transfer rate)
Latency 43 ms
Jitter 1 ms

3.

Download Speed 5.13 Mbps (641 KB/sec transfer rate)
Upload Speed 0.69 Mbps (86.6 KB/sec transfer rate)
Latency 42 ms
Jitter 1 ms

4.

Download Speed 5.12 Mbps (640 KB/sec transfer rate)
Upload Speed 0.69 Mbps (86.8 KB/sec transfer rate)
Latency 43 ms
Jitter 1 ms

This circuit is DSL, and the quickest offered for the DSL type. I know

the DL speed is forecast as 6Mbps. But, I'm unsure of UL speed.

This is ATT. I don't know what "jitter" is, but 43ms latency seems

quite excessive to me. Although anemic, at least it's consistent.

The reason for my concern is that the older phone produced no "hog-

ging" at all. Then, the new phone rolled into town, and everything

clogged up during these synchronization process(es). But, my change

seems to have throttled the phone's network dominance. And, I've not

had any complaints regarding other phone functions. So, it appears

that all is well for the moment. I just wanted to verify that my change

was the customary adjustment for my problem.

Thanks.

If anything is being saturated it's your ISP upload limit. Check the phone backup setup. I'm not familar with the iphone backup BUT I suspect it's doing a complete versa a partial backup which could explain why the new phone is causing a problem.

I'm not familiar with the iPhone settings either(beyond configuring the LAN access).

But, I'll have a look at it. I didn't understand your comment - "versa" "partial"? Are

you suggesting the iPhone is performing a complete backup, when an incremental

would do, or something else would do?

And, do you agree that those latency times are far to large? Maybe I should have

a talk with my ISP. But, this is running a DSL "modem" that's at least 12 years old,

and more like 15. Then through the router. And on to a wireless desktop, positioned

less that a foot from the router. But, concerning the modem, I didn't see how that a

new modem would be much different from this one. With all timing on the line, there

is really not much for a modem to do anymore. It's more like a transmission filter,

than a true modem. Also, I forgot to mention that the modem is just on the inside

wall from where the phone circuit enters the dwelling. I think I've eliminated about

all the wiring resistance there possibly could be. On my part, anyway.

Oh, I see your comment - "versa" "partial". I guess that's supposed "complete versus

partial". I get it now. My was standing here, and I asked about the iPhone backup

configuration. She says all she's ever seen was simply "on" or "off". But I need to

review it myself.

Just for FYI, I'll post what I've learned from my pending iPhone review.

Thanks...

12 to 15 years is a long time. While DSL speeds are still affected by distance to the DSLAM, there are new modulation schemes that have increased speeds by an order of magnitude. You should check with your ISP if higher speed options are available. Unfortunately, many telecoms are running, if not walking, away from wired service and are either selling off their DSL service or leaving the in-place gear to rot. You may want to see if alternative service options, like cable or fiber, are available in your area.

Yes, a carrier change has been on my mind for a long time. It's just

that the current configuration is rock solid. About once a quarter,

someone contacts me to change the configuration. But, I've heard

plenty of horror stories with the new ATT setups, and much of the

same with TWC. These are my only 2 real options without some

some kind of satellite protocol. You know how it is, ISP's rank

just somewhere south of used car sales people. I guess I'm just

gonna' have to bite the bullet.
