Strict NAT when using PdaNet on S9 - Samsung Galaxy S9 Questions & Answers

I've been using PdaNet for a while now on my older Samsung phone and a few months ago I got the Galaxy S9 and Pdanet has been worse on it than before. As far as I know it's because of how the UPnP routing doesn't work on the S9 and how the software itself is at fault. I'm able to tether and get a connection with it, but I'm limited to a strict NAT and I'm wanting to make it open or moderate. The only solution I've seen so far is essentially using another computer as a router for the connection, but I've been unable to share mobile connection that way and would rather not have to buy a router if there is another solution to this issue. Thanks in advance

works on mine no issue. both Verizon and U1 version.

I have Sprint and the Samsung Galaxy S9, it worked fine on my older android

sounds like one of these things:
you're connected to a crappy router (like an Amped branded router). i have an Asus (NT-N66U) and a Linksys (WRT54G) that doesn't have those wireless problems.
you MAY have a faulty phone. emphasize on MAY.
you're out of range.
the antennas on the router isn't putting out a strong signal anymore because it's dying.
my money is on the wireless router you're running. if its not the hardware of the router itself, then its the crappy firmware on it (which might be remedied by DDWRT or Tomato, which can also boost the signal output in exchange for more heat/shortened lifespan).
Are you using the 5G wireless band (if your router even has it)? I've have nothing but problems using my 5G band on my Galaxy S3 and now my Note II. Like you, it connects and disconnects often, sometimes multiple times a minute.
I switched to the standard wireless band and I no longer have any problems. Honestly don't know if it's my router (Netgear N600) or something with the Samsung phones. The only other device I have that sees the 5G connections is my laptop and I have no problems remaining connected to that.

[Q] Portable hotspot sleep issue?

Since I'm pretty sure others here have used their ZLs for tethering via portable hotspot (I hope), has anyone had Internet speed issues when using the phone as a portable hotspot (from the perspective of the tethered device)?
Here's the whole story -- both myself and my husband have the ZL (6506). He has a tethering-permitted data plan with AT&T, and he uses the portable hotspot feature to tether to his Galaxy Note 10.1 tablet. He previously used the same functionality on the Galaxy S3 without issue, however since switching to the ZL, he's had serious lag in the Internet connectivity on the tablet. It seems to be a function of power saving features, because when the phone is plugged in and charging, the speeds are decent, but when the phone isn't plugged in, they begin to degrade. They get worse when the screen shuts off, too. We've checked everything related to sleep settings, Wi-Fi, etc -- everything to keep it all "awake" while using the hotspot to no avail. The data speeds become worse than dial-up and connectivity is very choppy. Stamina mode is disabled, as is low battery mode.
So, I'd like to know if anyone else has seen this on the ZL? I'd test it on my own phone, but I am not on a data plan that allows tethering.
I'm asking because we also suspect that this phone may have some bad hardware or a firmware issue (related to 2 now-dead microSD cards within the span of 1 week, but that's another story) -- if he is alone in this problem, then perhaps it's just a bad unit overall & it should be replaced or repaired. He's going to try repairing the firmware via PC Companion later today.
Thanks in advance!

I haven't tested this for you but as far as I know, your factory unlocked phone can use this function without any tethering data plan because your phone is not restricted from tethering comparing to locked phones.
So the fastest way is to test it yourself.

True, sort of. As I understand it, AT&T is still capable of blocking tethering with unlocked phones -- not on the phone itself via a tethering manager, as they do on AT&T locked phones, but certainly the network traffic, if it isn't masked, can be blocked. I suppose I could try FoxFi to mask the traffic, but that's a whole lot of hassle and risk (I'd rather not have my contract canceled, thanks) for very little reward.
I'm mostly wondering if anyone else has noticed an internet speed issue when using the portable hotspot on the ZL (even on any of the other models, not necessarily the 6506), especially when the phone goes to sleep. If you don't have a ZL in your hands yet, then you can't really help me .
I used stock tethering apps on unlocked and att phones. I have the unlimited 30 dollar plan that does not allow tethering

Without any problem but I am only test like half hour
And I am tmobile user and having c6506 too
Did either of you notice anything with upload speeds (especially if you run speedtest)? What we're seeing seems to be intermittently poor or nonexistent upload speeds when tethering a tablet to the ZL via Wi-Fi portable hotspot.
Bluetooth / WiFi Tether
Interesting post...
I usually tether over bluetooth, and while I'm pretty new to this device I know that I have had trouble trying to tether with various devices over AT&T before. I have a grandfathered unlimited data plan, and rarely tether, but once (~ a year ago) I received messages stating that if I attempt to tether again than my data plan would be changed to a tethering plan (limited data & much more expensive).
On my previous phone (HTC One X+, stolen) - i had to change a line in the telephony.db from 'broadband' to 'pta' in order to avoid this. ( I think the argument was that 'broadband' notified AT&T that the device was being used as a hotspot and 'pta' acted like it was a cell phone accessing the data..
I am currently using the PAC (Paranoid/AKOP/CyanogenMod rom) at the moment, and it will allow me to tether, but is there something I can change so that AT&T won't be (so readily) alerted about it?

Rooting Samsung Galaxy s3 sch-L710 for tethering

I have Sprint service and was told that they're very strict on Wi-Fi tethering so I wanted to know if I got my phone rooted and used it as a hotspot for my Xbox 360 and laptop will Sprint know and try to charge me? Will the root turn it into a mobile hotspot?

Most custom roms have the native hotspot hacked. As far as Sprint seeing, I've never heard of it.

if you are willing to spend money, foxfi works fine too
I've been using it for almost a year now
Sprint knows when they see an excessive amount of data being used. They can't do anything about it unless you specify that your device is rooted.(Modified)
They do have specific tricks for customers with high data use. They disable the main tower where most of your data traffic comes from, but leave surrounding towers alone. That one tower will have LTE slowed but 3G will be at regular capacity. It's only done for about 2 to 3 weeks and then enabled again.
Basically, it's spot checking.
They've done it to me on 3 different occasions in 3 different areas across town. And I always check to see if it's the case by going to the next nearest tower and doing speed tests in the area.
(Just try to stay under 50GB and you'll be okay).

Wifi Hotspot / Tether on StraightTalk

My Samsung Focus S windows phone is going south on me and I'm looking for a replacement phone. I'm considering the Unlocked Amazon Fire Phone for $199. I will be using it with my StraightTalk Sim card.
I use my phone as a local hotspot when my sketchy internet service isn't working at home. Has anyone tried using this phone with StraightTalk and getting the WiFi Hotspot option to work?
I'm open to other phones that can be easily configured to enable WiFi hotspot on the AT&T network via StraightTalk.
Thanks In Advance
You can share your internet conectin, havent use it mutch but it works

I don't know about StraightTalk specifically, but I've used the tether before with T-Mobile (US) and it worked well.

Portable WiFi router with phone as a USB modem?

Does such a thing exist where you can USB tether to a portable WiFi router to use your 3g/4g phone data and allow others to use your signal. This would be for an unrootable Android phone.
I might be not getting your question right, but doesn't Portable Wi-Fi hotspot feature on Android does the exact needs?
I was looking to get around paying Verizon $400 per year for using WiFi hotspot on an unrootable phone.
I bought a Nexus 6 and don't need a router.
