Wifi slow to connect (Raphael, Wizard and Tornado)

I gotta know if anyone else is having the same problems connecting to wifi as I am. Whenever I try to connect to my wireless network with any of my devices, it's sporadic. Sometimes it'll connect right away. Most of the time, it takes two or three minutes (!) and sometimes it'll puke on itself and say it doesn't see the network.
In the latter two cases, I can delete the profile for the network and power-cycle the device and it'll connect to the network almost immediately. As you might guess, this is an annoying process to go through.
It never really bothered me until my wife got an iPhone and it connected immediately to the network and does so EVERY TIME SHE USES IT!
Can anyone help me out? Why do these devices take so darn long to connect?
This is the second router I've used (first was a Linksys, currently I'm using a Trendnet), the Raphael (Fuze) and Tornado (SDA) are running their stock ROMs. The Wizard (MDA), I've gone a little flash-happy on, but I've encountered the same problem with all ROMs I've tried.
I'll admit I haven't checked what channels neighboring wifi networks are using (I'm pretty sure I'm the only one on my channel), but when I first got my Tornado and Wizard, mine was the only network (visible) and I was still having problems. And regardless, is the wifi radio in the iPhone that much better than my HTC devices?
(Just a side note, I have three wireless laptops that are all able to connect to the router without a hitch, adding to my belief that my network is on its own channel.)

Just wanted to update everyone that, last night, I checked the wireless networks I could see from my house and none share the same channel as mine, however I didn't take overlap into consideration. The lack of response to this thread would suggest to me I'm the only one encountering this type of problem, so I'll do some experimenting in an area with no other wireless activity and see if connecting is still slow.

O.K. I tested the Wizard and Raphael with a router in an area with no other wireless activity and discovered the following:
If the devices are set for DHCP, it takes a long time to connect. However, they did connect and remain connected without any problems.
If the devices have static IP addresses, they connect immediately and remain connected without any problems.
Conclusion:
The DHCP discovery on these devices takes too darn long to acquire addresses. That, and the slightest bit of EM noise can cause them to crap out. Since I don't have problems with other wireless devices (laptops, iPhone), I'm left with the assumption that either the radio is poor quality (unlikely) or the driver needs some serious fixing (most likely).
When and if the noble developers of this board get linux up and running on the Raphael, I'll be more than happy to test it out.
Since this thread was self-answering and would seem to be of little value, please feel free to delete it, moderators.

WiFi randomly fails to connect after last update

I've had my Transformer for about 2 months now and my WiFi connection has always been reliable and robust, but ever since the last OTA update (8.4.4.11) it's gone flakey. I know the problem is not my wireless router since WiFi was working great before the update and I have lots of other devices that connect without any issues.
At least once or twice a day after resuming from standby, the WiFi icon stays dark and no amount of trying to reconnect will get it back. After a few tries, I can actually watch the checkbox for WiFi settings toggle on and off repeatedly by itself.
I've tried changing the WiFi disconnect policies, closing down apps, and stopping non-critical processes but the only thing that fixes the issue is to power down and restart. WiFi will then work for awhile but eventually goes out again.
Anyone else seeing this?

same thing here =/

same here and i'm getting piss off at the fact that new updates is screwing over my wifi connection.

FWIW - it's also discussed in these 2 threads and is worked around by giving your TF a static IP. Not ideal, I know, but at least it will get y'all working.

there has been issues with other tabs and OTA upgrades with WIFI. Try brouse in the A500 forums. There was a file to delete that fixed the issue. Must have root access.

That's kewl and all but what if you connect to different AP's during the day. I access through my EVO 4G while at work and then access my home network when I get home. This may or may not work. I'll have to see when I get my TF on Thursday. Thanks for the quick links though.

You can also increase the dhcp lease time in your wireless router, it also works for me.

Download WiFi Analyser, which will show you, which IP data you need for static configuration.

Not exactly the same issue and I already set up static IPs for all the devices (32 of 'em!) on my wireless network long ago.
I did find that one particular app was probably the cause (PCFile Sync) and since replaced it with another having similar functionality, but I still very occasionally lose WiFi and have to reboot.

I've been following this issue since I started having it on the 3.1 update when I unboxed the thing, so I'd really like to understand what issue you found with PCFile Sync, or at least what led you down that road.
Up to this point because of my specific goings on I've been thinking it was more a DHCP/routing issue and not in fact a WiFi/connection issue - i have strong connection before and after whatever the event that shuts things down is, just no traffic.
A little more info here as well - http://forum.xda-developers.com/showthread.php?t=1191792

The behavior I described in my initial post (watching WiFi toggle on and off in settings) seemed to suggest something was blocking or interfering with the normal connection after resuming from standby (I have my WiFi disconnect policy set to turn off WiFi when the display is off).
So I just started closing down apps that had WiFi access and when I killed PCFile Sync (which I use to sync files between the TF and an NAS), the problem went away. I'm now using FolderSync Lite which doesn't seem to cause any issues, although on rare occasions WiFi will still loop for awhile before connecting.
This never happened in HC 3.1 so I think it's a vulnerability in 3.2 under certain conditions ... and those not using a static IP on their LAN are probably seeing something similar happen.

You know, after using my TF after the update, I think what this wifi bug is really just a fix gone wrong. Maybe it's some condition set to turn on wifi only when in use (to save battery life, or allow certain tablets that won't go into deep sleep to go into deep sleep or something like that) but it's set with some super sensitive conditions that make it turn off unless there is an actual request for internet?
My bar goes from blue to grey/white after a minute or something, but I can seem to always access some webpage when I click it from an app. Hmm.

This happens to me with 3.1 randomly, though my policy is set to keep WiFi alive and I never used this PCSync app.
In my opinion the Android Broadcom WiFi card driver is buggy, because the SGS2 with android 2.3.3 has similar problems and also a Broadcom card.
So I guess it has nothing to do with the Android version, but is a buggy WiFi driver. I remember, that I had similar problems with an Intel card in a Toshiba notebook years ago and it was fixed with a driver update.
The question is, who develops the drivers, Google's Android team or Asus & Co? I guess the later? If it are the manufacturers, I find it strange, that Samsung has similar issues.

+ 1 on this very frustrating bug; since upgrade to 3.2 it happens every now and then ; as I did not install any new Apps I assume that this is just a very annoying 3.2 bug...
Anybody with any solution plz?

A german TF owner reported in a german Android forum, that he phoned Asus support about all well known 3.2 issues and they told him, that a firmware fix will be released by OTA next week.
Knock on wood that this is true.
So far ... static IP.

I have had several other problems with Broadcom WiFi drivers, so this doesn't shock me at all.

bluetooth tether issue

Why do some users achieve tether and others don't especially with the same tablet and phone. I had a theory and tested it and was right. For those that have managed to get as far as I did with connecting to your phone and having both Bluetooth icons but not be able to connect here is why. Your on wifi it only tethers on 3g I don't have 4 g by me so can't comment if it will work or not. I tried on wifi and the load bar would move an inch and stop then disconnected from wifi and TA DA it achieved tether. Why I have no idea but it works as a matter of fact I am posting this on my xoom connected to my bionic.

I've been using Bluetooth Tethering extensively. It works really well, but is a little temperamental.
On my phone (HTC Magic with a Gingerbread ROM), the *first* time I connect the Xoom, tethering appears to work but doesn't. So, on first connection, I always disconnect, then reconnect, and then I'm good for the rest of the day. This is most likely a bug in my ROM's Bluetooth implementation, but might be more widespread and might be what's making you think Bluetooth tethering just doesn't work at all.
Also, occasionally, and for no apparent reason, the bluetooth stack on the Xoom will go completely non-functional. All I have to do is disable bluetooth, re-enable it, and re-tether to the phone. Only a few seconds, and I'm back in business.
While a perfect Bluetooth tethering solution would be really nice, these two issues are minor enough that I'm considering not upgrading my now ancient phone until the 3 year contract is up.

[Q] Pairing with TF101 tablet

I have looked but can't find a solution. I have the transformer 101 tablet and can't get it to connect to my tmobile mytouch 4g. I'm posting in this forum because I can get the tablet to connect to my computer so I figure it has something to do with the phone. I'm trying to get a bluetooth connection so I can tether. I don't use much data but I'd like to know I could do it with the tablet and make a connection if wifi not around. I have rooted and installed stock Android 2.3.4. I don't know much about Bluetooth or WIFi but from my readings I'm think it might have something to do with PAN BT profile. If this is the case, is this a software thing? Is their a ROM that has the PAN BT profile? I like some of the Sense Apps so I'd like to stay with a stable Sense ROM. I'd like to be able to stream Navigator when I need it or brows the internet while waiting in the parking lot for my husband. Yes I can do it on the phone but my eyes are bad and a larger screen is so nice. I don't come anywhere near a GB of data each month...just want to be able to connect when sitting in my car and give myself a bigger screen.

I must be missing something here. Why not install wifi tether or one of the myriad sense 3.5 ROMS in the dev section that ALL have a working wifi hotspot?

Well my thinking may be wrong on how Bluetooth and wifi work but I was thinking there isn't always a wifi connection, but there would always be a signal with bluetooth connecting the tablet to the phones 3G and 4G. I was hoping that, if tablet paired to phone when traveling, I could use the bigger screen on the tablet and navigation would run like on the phone. I'd like to use the tablet as much as possible and I'm thinking that in the country there wouldn't be any wifi hotspots. Sorry if I've got this all wrong. Most of the time I would use wifi and I've only used that at home or work....never hotspots.
As far as ROM's go, I was thinking of the Virtuous Affinity or Unity ROM's but didn't know if they were going to give me the bluetooth connection I was looking for. I can't remember but thought I read that you couldn't do some things in 3.5 that you could do with ealier versions. Do you know why the tablet can't connect with the MyTouch? Is it the PAN BT profile. I know the tablet doesn't do adhoc. Sorry but I did try to read up on it. I was just thinking of the message I see. They are paired but they wont connect. I click on the bluetooth device but it doesn't connect

I've tried to understand what your asking but I'm still confused. Are you trying to make a wifi hotspot off your phone, then connect your transformer to the hotspot, to use the internet?
If I helped, give thanks, if you please.

There a couple things wrong with this post 1) the tablet does support and use AD-HOC tethering. I know that for a fact because I've had people connect to my home network via my tablet just to show off. Pretty embarrassing making them use my Android Tablet to connect their iPad to my home network. 2) If you are just wanting to use your tablet as a navigation unit, use the Google maps while you are connected to WiFi to find directions to where you want to go, then press the navigate button. It'll work w/o a data signal. I've done it several times. 3) you don't need blue-tooth to bridge the Tablet to the phone. This doesn't work like Blackberries and the playbook. You can use the Wi-Fi Tether .apk from Google's source code to do just that. [http://code.google.com/p/android-wifi-tether/downloads/list] 4) There has to be a blue tooth stack installed on the Phone, and on the Tablet that will allow them to share blue tooth connections for Internet. I have TF101 and have yet to find such a BT stack.

[Q] Same but different WiFi issue plus...

Hey guys. This is my first post here. Checked all the troubleshooting threads and did not see this. Have seen the issue similar on other forums and sections, but my situation is a little different.
I have a rooted 16GB S4. I have been using the same wifi connection since August 2nd. The wifi on my phone, computer, TV, and Xbox have all been working this whole time. This afternoon I tried to check something on my computer and had no internet connection, but was using my phone. Thought the issue was my computer. Left. Came home. Computer is connected fine. My phone, my wife's iPhone 4s, TV, and Xbox will not connect to the network at all. So this situation is a bit different as I have been connected for 3 weeks and now wont work. I assume its not my phone because so many other devices dont work either. Not to mention it's both IOS and Android. Anybody have any ideas? Thanks a lot.
My plus is just something small. Yesterday my lock screen blanked out. I have my other lock screen pages, but my page with the date and time and all just randomly went blank and will not come back after reset.

If I read everything correctly then you don't have an issue with any of your devices. Chances are it's your wireless router. I would recommend replacing it to see if that fixes the issue. You can always buy one from Best Buy and take it back if that doesn't fix your issue.
EDIT: Forgot to mention that it may be the way your router is configured. (I doubt it's your ISP if something is working but other stuff isn't.) What kind of router do you have?

I think its a netgear. We are living in a downstairs apartment. All my devices now work. It was weird. First nothing was on. Then just the cimputer. We went to sleep and woke up and phones were working but not tv or xbox or computer. Now everything is fine again.... I did send an email to my landlord and ask her to unplug the router for about 30 seconds. She may have done that....

I definitely think it's the router. Netgear isn't the best around, and I have found that they do have problems from time to time. If you had access to the router yourself that would be the best way to troubleshoot the issues.

If things were working fine for some time then just started acting wonky, it wasn't anything your devices (S4, iPhone, computer or xbox) could've done, per se. Something had to have changed with the router - not that it's going bad or that it sucks, but something was altered. The smallest changes in networking can make the biggest difference. Don't just buy new devices and throw out the old when an issue arrives.
That's great its working now. For future reference, you should get your own in-apartment WiFi, like "Clear", cheap and works well in most areas, this would narrow down your possibilities of your internet not working properly on your S4 and other devices.
