Set MTU on Rooted Galaxy Tab 2.3.4 - Galaxy Tab Q&A, Help & Troubleshooting

I'm trying to set the MTU of my Tab to 1472 to connect it to a Motorola Triumph via ad-hoc wifi (Barnacle). The Tab is rooted and I've replaced the wpa_supplicant file with one I found on the Net the has been modified to see ad-hoc WAPs with the Tab.
I'm running Barnacle on a Motorola Triumph that supposedly has an MTU of 1472.
I can connect my Win7 Dell Netbook to the Barnacle ad-hoc WAP and I have full web access (chg'd Dell MTU to 1472 to enable this).
When I connect the Tab to the Triumph Barnacle WAP, I can only connect to Google sites via the Tab's browsers (stock and Skyfire). Some info I saw on Howard Forums has blamed wifi connection problems with the Triumph on its non-standard MTU setting.
I'm a noob at this stuff, but I think maybe changing the Tab MTU to 1472 will help me connect.
Any thoughts?
Can anyone tell me how to change the Tab MTU?
Thanks!

Did you ever get help from another source on this or did you figure out how to change the MTU on your Galaxy Tab? I have a Galaxy Tab and I am thinking about buying a Moto Triumph and I would like to tether them if I can.

I never got any response on this post so I just gave up on it.

Yeah, I haven't been able to find anything either. I just put CM7 on it and WiFi tether works great.

Problem w/wifi tethering after install Gingerbread

Hi Forum,
I cannot get my Sprint tab to see my phone after installing Gingerbread. My computer can see the phone and connect it, but the tab won't. Before Gingerbread, I was able to scan and connect to my phone and tether just fine. I tried diff. wifi tethering app. Currently use Barnacle. My tab is not rooted, but that should not be a problem.

which version of GB do you have installed? Is it the stock sprint update? Have you tried the WPA supplicant fix for it yet?
I using Sprint OTA Gingerbread, 2.3.4. Build number EF17. I have not tried the WPA supplicant fix. I did not have problem with this issue on Froyo. I will research on this. I would like some tips if you got them. Thank you !
I found a link on the issue, but require root. I am reluctant to take this step. It is not that I don't know how to use Odin, but removing root is a pain.
Here is the link to WPA supplicant if any interested.

from everything i've read, you won't be able to connect to ad-hoc mode wireless (most wifi tether apps) without the wpa supplicant patch. you might look into a wifi tether app that will do infrastructure mode to get that working again.
@ pvtjoker42,
Thank you for the tip. I did some further research and the Wifi Tether app works in infrastructure mode too. If any one interested, here is how you do it. Choose device profile- I chose Samsung Galaxy S. I also tested Samsung Galaxy Indulge. Under Setup-Method, choose Softap ( master). Now your Samsung Tab will see the phone. This app drains battery like no tomorrow, much more than Barnacle.

[Q] wifi infrastructure mode

Anyone got anything working for this ?
I've tried wifi tether for root users
and lots of others.
Nothing allows for infrastructure. Even tried 3GHotspot.zip and Black Hat zip .
Any help ? Anyone got this working ?
Check themes and apps threads.. if you want to tether to Windows or Linux or another android device only way is wifi tether v3 beta 4 or higher enable mss clamping in settings and you can tether using ad-hoc but that is about it. Is this what you are trying to do??

I'm trying to connect my tablet to share my 4G.
Tablet only connects in infrastructure, not adhoc.
If I can fix on my phone ie add infrastructure, then I'll be ok. Otherwise I'll need to root and mess with the files on my tablet

You might have better luck finding a thread for your tablet and finding out how to change the wpa_supplicant so the tablet will detect an ad-hoc network. I used to have a Samsung Galaxy Tab 7" and had to find a patch and replace the wpa_supplicant (after rooting) so it could detect and connect to my android phone. What kind of tablet?
Only other thing I can think of is install the Verizon Hotspot app and pay for tethering.. that is infrastructure as far as I know.

[Q] how to use adhoc wifi?

As I know adhoc NOT supported

There is something called "wifi Direct" which might be another name for the same thing. Read about it in the user manual, which can be downloaded from Samsung in a pdf. Sorry no link.
If your trying to use the Adhoc to tether other devices to your Note to use it's data connection, then you go into your Settings -> Wireless and network -> Tethering and portable hotspot, enable this, set up a password if you wish, then you can connect to it via wifi now.
Does the phone see wifi adhoc?
Sorry to bring up this thread, didn't want to start a new one.
Now that many people own the nexus. Can someone tell me if the phone can connect to a wifi adhoc? To avoid misunderstanding, this is not the same as tethering phone's internet to other devices (that what's Wifi Direct is about, I think). This is the phone using internet from pc via adhoc wifi (for example using the program Connectify).
Thanks
There is a guide for galaxy s2, just google it (cannot post link), you need to change wpa_supplicant file
Worked for me
sorry for bringing it up again.
changed wpa_supplicant to the one from galaxy s2 and changed permissions. But didnt work for me!
Anyone got files for me so i can use adhoc wifi?
i really need it! thanks a lot guys

If you used this guide "Connect to adhoc Wireless Networks on your Galaxy S2 (SC-02C)" the is should work, maybe it depends on firmware, I have N7000XXKK5
well with this wpa_supplicant i can see the ad-hoc but i cant connect.
And although my note freezes if i use this one. isnt there one especially build for the SGN?
i have kernel N7000XXKK9
I don't understand, if you want to connect to a PC via wifi to use the PC's internet, then isn't it then down to setting the PC as the adhoc and connecting you phone via wifi as if it was connecting to an wireless router? Or Wi-Fi Direct (which is the phone connecting to other devices, not other devices connecting to the phone i.e. tethering)? Can anyone clarify what the issue is?

The issue is that, by default, the Nexus can't see adhoc wifi and therefore can't connect to it. You need to somehow modify wpa-supplicant to be able to see adhoc wifi.

PDANet

Has anyone tried PDANet for tablets with the 7.7 yet? I could never get it to work with my P1010 but I am hoping it will work with this one.

First of all, of course you couldn't get PDANet to work on your old P1010, it's a WiFi only device, and PDANet is an app designed to share your mobile (3G) connection via WiFi, Bluetooth, or USB. What exactly did you hope to accomplish with PDANet on a WiFi only device?
Finally, assuming you got the 3G 7.7 (P6800) and not the WiFi 7.7 (P6810), you don't need PDANet at all in order to share your 7.7's mobile 3G connection to other devices. It has mobile tethering right out of the box. Just go to Settings ==> Wireless and networks ==> Tethering and portable hotspot.
Done!
I am sorry I did not give enough information. I wanted to use my droidx as a server to get internet access for my p6810. I do this with my phone and tablet PC. I now know that it is extremely limited with honeycomb.

Ok, I understand now.
In this case, you shouldn't really need any additional software for your P6810, assuming the tethering software on your DroidX supports WiFi tethering. You should be able to connect the P6810 to your DroidX just the same as you would connect to any other WiFi AP.
I do need another solution as I don't want to pay Verizon another $20/month to tether.

wi-fi tether issues

Anyone having issues using any wi-fi tether apps from your phone with this tablet? I get "connecting" and "obtaining ip address" when trying to tether with my nexus s 4g (rooted) but i can't get them to work. The same tether apps from my phone work for my laptop but not this tablet? I can use the bluetooth tether with these same apps but the wi-fi tether doesnt' connect. I guess my questions are:
1. anyone else having this issue
2. if so, is connecting bluetooth from the tether app slower than connecting using the 'wi-fi' option
THanks in advance for this!

Go check your nexus s 4g's tethering mode. Some phones only work in the ad-hoc mode instead of the infrastructure mode, and most of the tablets don't support ad-hoc mode. PC normally supports both modes.
I am having issues. I create a hotspot using my s3 but my nex7 can't connect with a password or not. I got the Bluetooth tether to work instead. Using the FoxFi app and I'm not rooted for either devices.
Sent from my Nexus 7 using xda app-developers app
Works fine with my I9000
Try changing the wifi hotspot name in Foxfi. I could never get Foxfi to work with my S3 and Windows 7 laptop using a password. Without a password it worked fine.
I ended up getting SVTP Wifi Hotspot and USB Tether for my S3 and now I can connect with a password to my laptop.
Will be getting the Nexus 7 tomorrow so I'll check out how the SVTP works with that.
Nexus 7 doesnt see my phone's wifi broadcast
Using a rooted HTC Rezound to offer up the 4G...my iPads find the broadcast in seconds, laptops as well. Nexus 7 has yet to find it. Tried different channels, different settings, different wifi tether pgms, still nothing. My phone apparently cant seem to connect via bluetooth properly either, tried foxfi/pdanet. I dont care about the iPad having network access, its a paperweight after my nexus arrived, but I would like to be able to use my nexus on the road/at work/etc. Any help would by spectacular...
I had absolutely no issue using FoxFi off of my droid bionic to my nexus 7. It initiated and connected within seconds.

This happened on prime for a few firmware versions where ad hoc tethering connections wouldn't work. The solution is here http://forum.xda-developers.com/showthread.php?t=1438297. It should work for nexus 7 also. Make sure to follow instructions and set permissions correctly. It should work instantly. No reboot required.
Edit: might need some adjusting. Since i just looked and saw nexus 7 only has one wpa supplicant file in /system/bin , a complete swap might do the job. Of course rename and backup the original wpa supplicant file. Set permissions correctly on new file according to op of that thread. Post back of it works or not.

The iPad can connect to an ad hoc network, the Nexus 7 can't. Most wifi tether apps are ad hoc so that's why it won't see the network. You need to be able to tether with infrastructure mode to get the N7 to see the wifi network. If there is a hack to make your Rezound's stock hotspot app work, that would be the best way to tether to your N7, because it would be infrastructure.
using Foxfix here from galaxy s3 to nexus7 without issue, blazing faster than my WiFi connection at home..4g LTE rocks, hope the next nexus smartphone will support LTE speed

have you consider tethering throught Bluetooth? I used that with no issue with my rooted Nexus Galaxy to my Nexus 7.
Just so you know, my wifi tethering work too.

My phone doesnt support the bluetooth PAN...I think I need to follow the other instructions. Im really new to this, so hopefully someone can hold my hand.
I'd be surprised if the N7 didn't recognize adhoc networks. When Asus put out the TF101 it initially didn't recognize adhoc, but the first software upgrade fixed that. As far as I know all of the Asus tablets now support adhoc. Doesn't make sense that the N7 would not have that capability. - sheureka
Just got my N7 today at work and luckily I can tether with the stock WiFi hotspot app on my HTC wildfire s. For some reason no one can connect to the WiFi at work so tethering is all I have at lunchtime.
I'm able to connect to my rooted e4gt using wireless tehter with no problems. N7 is 100% stock.

Then or also paying $20 to use the internet u already pay for? Not knocking u just asking because if your on Verizon no WiFi or Bluetooth tethering will work without paying the fee
My GNex tethers just fine with the N7. Bluetooth tether sucks however. Connects and stays connected but does not work with anything except the browser.
I managed to tether through wi-fi and bluetooth. Try using a CM7 RCA rom, or something off of here if you like. The built in features for 2.3 and up are great for tethering over wi-fi. Just make sure the rom supports it now since Im using CM10 and for right now wi-fi tethering does not work. Best of luck to you.
