Wifi or 3G?

im sure this is probably a stupid question, but should i just use my 3G at all times? i downloaded wifisync so it automatically connects to a wifi when in range, but which is faster? I also have a high speed internet connection at home which is 54mbps, so if i connect to that wifi... will it be faster than the regular 3G service?

Yes, your wifi will be faster than the 3G. It's really your preference.

oh ic... but since i have wifisync running, whenever i dont have a wifi it will be disabled so then ill have my 3G running....correct?

correct
The G1 can determine if you have Wifi/G3/E/G in your area and switches between the fastest possible method. For wich it has access parameters

3G is usually a bigger drain on your battery, since your phone's signal has to go farther than it would for Wifi. Wifi is extremely localized compared to 3G, and takes less effort for the phone to connect and communicate with wifi.

I've always found the opposite to be true. Wifi always kills my battery way faster than 3G.

wi-fi kills my battery more than 3g if the wi-fi is on and not connected (scanning for network), but if the wi-fi IS connected it seems to drain slower than the 3g

Wifi sucks on touch HD

When I first bought the touch HD I was thinking how good it would be to have this phone while having wifi with the lack of 3g for tmobile in the us, but it turns out that the wifi acutally suck! I have a iPod touch 2g And the wifi works great with blazing speed. I can't seem to detect my wifi at home mean while I'm connected on my wifi with my iPod. I been very disappoint with this phone for simple fact that this phone recieves wifi poorly. Anyone can help me out with this problem would be much appreciated because despite the wifi problem I love the phone cause the 3.8 screen is so damn sexual lol.

I've no such issues!
Try to set wifi power options to performance. Also, Enabling G Mode (with SKTools is one of the ways) helps improve speed.

Thanks for the info but it might be the lack of range of my router cause I have been on my wifi with the phone before but I get disconnected frequently and most the time it doesn't even show up or detect it but I don't have that problem with the iPod. With iPod I seem to get wifi everywhere. I'm starting to believe the iPod is better might sell it and get a iPhone or maybe a hero but don't know if I'm willing to spend 600+ on another phone

Next time put [rant] on the title

My wifi connects well to open, WEP, and WPA connections. I tried numerous access points (at least 30), even 802.11n APs in mixed g mode. It even connects to Apple Airport (802.11g). The connection is stable both on power saving and best performance, but I think I get much better speeds on average with best performance.
Its wifi range is much better than my little HP 613 smartphone, but again worse than my notebook. I get 54Mbit connection with signal quality of about 50% at 10 meters through a wall and then it automatically finds another channel on another AP. It roams (handover) APs better than some Lenovo r61 laptops around!
But I am not satisfied with its speed (even on best performance) - it finishes copying a 700MB file on a 54 Mbit connection in 30-40 minutes using total commander and saving on storage card. That means average speed is around 300-400KB/s - laptop does the same (same AP, same file, same network settings) at 1.6-1.8 MB/s in around 7 minutes.
I also noticed that saving on storage card is slighty faster than into the main memory...

I can't seem to detect my wifi at home mean while I'm connected on my wifi with my iPod.

Hmm, are you sure that you don't compare two different situations ? Did you also try connecting to Wifi with your iPod while already being connected with your Blackstone ?
My personal experience shows me that the Touch HD seems to have a better radio than the iPhone 3G. Have you upgraded to the latest Blackstone stock ROM and radio available on the HTC website or XDA Devs ? Whether or not the radio also affects Wifi unfortunately I don't know.
Moreover, use WifiMonster to monitor the strength of the signal, it'll help you discover the best spots for using Wifi. I even receive Wifi signals from the neighbors' houses in my own house (not speaking about appartments), of course that always depends on the room !
BTW I'm pretty sure that a Hero won't solve your problem, it's the same old hardware specs as on the Blackstone.

The Wifi on my device works perfectly and i have had no issues at all with signal or quality. I have had more problems with my ipod than the HTC, are you sure its not the WIFI AP you are trying to connect to? Also are you using stock rom or custom?

I'm using the Energy ROM. I'm assume its my wifi signal its very weak and my touch hd cant seem to detect it. With my ipod i shows up and i can connect to it...will updating the radio make a difference?

I came across a startling discovery the other day regarding the Touch HD wifi. I was also having issues at home with weak wifi signal. I didn’t seem to have this problem with public access hot spots.
I have a Logitech wireless mouse connected to my computer and very rarely turn that computer off. I found that when my computer was off I would get a rock solid connection to my home wifi, but when the computer was on it would drop in and out. I narrowed it down to the wireless mouse was interfering with the Touch HD wifi connection.
I tried all different channels on my router, but as long as the Logitech mouse was plugged it I would get wifi dropouts. But as soon as I unplugged the mouse and the radio dongle, I wouldn’t have any problems with the Touch HD wifi.
I can’t comment if this is your issue, but something might be interfering in the 2.4Ghz with wifi.

Guys,
Sometimes even cordless phones, microwaves, etc will interfere with the connection.
Cheers.

As Poison Wolf correctly pointed out, other household items can interfere with the wireless frequency. Try changing the channel that's being used to transmit from your box (This will involve changing some settings on your wireless router so do some research before you fiddle around with it) I have had to do this before and can confirm it can make a massive difference.

Everybody has this problem because the card seems not capable of more speed.
But it seems nearly nobody cares.

Stron,
Hmm, interesting. The only reasoning I can think of is that perhaps there's a limiting factor in order to reduce the heat or something? I don't see why they would cap the speeds.
Cheers.

What if it is capable of connecting at 54 Mbit, but can actually do only 11 Mbit? Nice trick. I hope it is just a bad idea.

HSPDA I think
Bascially when my phone download it displays a H and when it's not it displays 3G

Yes, it's HSDPA. It's faster than 3G, so it's good if you see that, it means that your provider has faster internet
On Nokia handsets, HSDPA shown as 3.5G .

uhm does that mean i have am using a premium service that requires me to pay additional lol?
it wasn't like this. It recently became H from 3g only. :X

I've never heard of HSDPA being charged as a premium service. It's just your providers network.
Anyway you can disable it from them settings if you want. Just go to Settings>Wireless and network>Mobile networks>Network mode and choose GSM only. An alternative is to use APNdroid from the market.
I disable it when I'm in a WiFi network or when I don't need a data connection because it uses more battery.
I use the "WCDMA only" (forces HSDPA on) when I want a data connection so my phone does not switch to GSM automaticaly. Be careful if you use that option though. If you move to an area with no HSDPA coverage, your phone won't switch to GSM and you'll have no network connection

That's partly right. It does not send or receive data through the mobile data connection but that does not mean it switches to GSM network. It stays connected to the HSDPA mobile network just handles the data requests through WiFi. In my experience anyway

True, but if you don't go into WiFi/Advanced/WiFi Sleep Policy and set it to NEVER, when your phone goes to sleep so does WiFi, which causes the 3G radio to turn back on and using wireless data for updates, email checks, etc.
Long story short, if you're spending a lot of time in a WiFi area, set it to never sleep to save a lot of battery and a bit of data usage.
If you're moving around a lot, leaving WiFi on when the phone is sleeping will use more power, because not only is your 3g radio on, so is the WiFis, as it's constantly looking for a known network to hook up to and scanning for new ones.

Hi I have a few questions about your comment here. I am in an office connected to wifi all day at work and when at home connected to wifi. When I look at battery usage it states
Display 46%
cell standby 19%
phone idle 12%
mario live wallpaper 9% (highest ive seen it but it is the best thing on this phone)
...
...
Wi-Fi 2% (lowest item in list)
Are you saying if i tell it to never make wifi sleep then cell standby usage will go down and i will use less network data? and battery usage will be less then if it makes wifi sleep?
Also if i do this when I am not in office/home and i disable wifi will that also save me some battery?
At the moment i just have wifi on all the time and let the phone use what it wants to.

I believe "cell standby" does not talk of ACTIVE 3.x/2.x G connections! So you should not be looking at that parameter. However it is interesting for us to know that WiFi hardly use any power. "cell standby" should only talk of when mobile is really in standby or display off, low power (suspended) mode.

3G radio uses a LOT more power than short range WiFi. When WiFi is on and connected, the 3G connection is totally turned off. Totally.
Think about it this way...once you get past the new and shiny phase of owning your device, it probably spends MOST of its time with display off and sleeping. So, it will spend a LOT of its time connected to 3g if you let the WiFi go to sleep.
Turning Background Data and Autosync off will prevent the 3G radio from switching back on when WiFi is sleeping (and prevent WiFi from using much transmitter power when awake as well). But turning off sync/background data is not ideal if you need emails or whatever as soon as they are sent, accurate weather forecasts, etc.
Least battery usage is of course in Airplane mode with WiFi and Bluetooth turned off as well, since there is no radio activity at all. But we bought these devices in part because they're connected and "always on" data is coming in.

Here is how I do it:
I use APNdroid to switch 3G off when it's not needed. I find that I only rarely need 3G. Seems that you do not need it either.
I leave WiFi sleep on because tbh I have no reason not to. When WiFi goes to sleep 3G does not autoconnect anyway because of APNdroid.
That way the phone uses plain 2G when no data are needed. When data are needed it uses WiFi most of the time and 3G only when no WiFi is available and I manualy select to put 3g on

G = GPRS ( General Packet Radio Service )
E = EDGE ( Enhanced Data rates for GSM Evolution )
3G = 3rd Generation ( I unno, wtf. )
H = HSDPA ( High-Speed Downlink Packet Access )
Basically G(PRS) operates over GSM, it's from dial-up speeds to twice as fast as dial-up.
EDGE operates over 2G, it's almost as fast as standard DSL, about 400kbits and a maximum theoretical 1Mbit.
3G operates in tandem with HSDPA, infact technically HSPA is the technology that is used on the 3G network. It is typically up to 7.2Mbps, with a maximum theoretical of 14Mbit.
HSDPA and HSUPA are specific aspects of a HSPA enabled system. They are Down link and Up link capability respectively.
When you see H, the phone is going from a stable 3G connection to a boosted power consuming ( which is why it isn't constantly on ) state in which it can download very quickly.

[Q] G2 WiFi speeds N+AC

Does anyone notice there's a big bug with WiFi on the G2?
I have 2 WiFi ac routers, one at home and one at the Office, an Asus RT-ac66U and a Linksys ea6700. Both capable of 1750mbps max speeds.
Internet speeds are 120/6 and 200/20.
Scenario is exactly the same for both routers;
When fresh reboot the router, G2 connects at a speed of 433Mbps.
Speedtests show results of 119/6 at home and 190/20 at the office.
Great you would say!
But here goes. Once WiFi get disconnected and reconnected, speeds go down to ~40mbps. No matter what I do!
These are N speeds, not AC
When looking at connection settings it still shows a link of 433mbps
Tested dozens of times, on both routers, so it has to be an issue with the G2.
Anyone else noticed the same??
DAMN, should have been in Q&A, mods plz move

I'm not an expert on wi-fi, but have stumbled through setting up several routers around the house. But I do not have an ac router.
Is the home router in mixed mode? Ignoring a/b/c for a moment and focusing on g and n (and implying ac), I have two wireless routers in the house. One runs N only (but both 2.4 ghz and 5 ghz) and the other runs G only. Now, my N router is capable of running in mixed mode (to handle both N and G) BUT in mixed mode, my max speed when connected in N is lower than it would be if I ran in dedicated N mode.
Most of my devices now are at least N (2.4 or 5) but I have an older printer and wii that only do G. But as mentioned above, rather than run my best router in mixed mode, I run 2 separate routers, one in N only and one in G only.
Maybe something similar might help with your ac speeds?

Really appreciate your input!
But I already tried settings like AC only etc. Doesn't make any difference.
Once connected for the second time and up to the router no more AC speeds...

Is there a way to test LAN speeds on Android? I have the same Asus router but my wan speeds are so pitiful that I wouldn't be able to tell if the phone was dropping to N speeds. If I could test speeds to my desktop across the local network I might be able to test what you are experiencing.

Is there a way to check on the phone, which band it's connecting to? I haven't found anything.
I have the same router and my issue is on reconnect. I leave my wifi on all the time. When I get home, it connects automatically the moment I pull up to the house. The problem is, the speed is severely crippled. Range is awesome, speed is bad. I have to cycle the wifi and reconnect. Once done, no more problems.
One thing I should note, I was having the same issue occasionally on my Droid RAZR after getting the ASUS. Does anyone know if they use the same wifi hardware? Maybe it's an issue with the router itself?

Don't know about an app to test lan speeds unfortunately.
Think a google search would come up with lots of options.
@crashN2u
I leave my wifi on too all the time for now, it keeps it at full speed then.
There's no way to check which band you are connected to.
Router doesn't have an option to choose AC Only, only N +AC
And in the mean time I have tested it with 4 AC routers, Asus RT-AC66U, Netgear R6250, Linksys EA6700, D-Link 868L.
With all routers exactly the same conclusion. First time everything is great. Excellent speeds. If you never turn off WiFi it remains at high speed.
But once you turn off WiFi on the Phone and turn it back on it immediately drops to ~36-40mbps max (N Speeds).
This remains until I rebooted each router and after that full speeds again.
It must be something in drivers LG used.
There's the solution to for, I'm sure of it by now.

Well, I can see I won't be much help -- especially since the same result on 4 routers!
I am not sure if the following app supports AC, but a very helpful and free app I use is called "Wifi Analyzer". I can't post links but that is the exact name (author = farproc).
It has many useful tools/functions that you may find helpful, switchable between 2.4 and 5.0 ghz, channel scanner, etc.
Does your 2.4 ghz N and 5.0 ghz N/AC have different SSID's? From what I read, AC is 5 ghz only and N can be either 2.4 ghz or 5.0 ghz. I wonder if you are dropping from 5.0 AC to 2.4 N because the 2.4 N is being detected as "stronger signal" than the 5.0 AC at reconnect time?
I named my 2.4 ghz N SSID as "Blah" and 5.0 ghz N SSID as "Blah_5ghz" just so I know what frequency I'm on at a glance (using a widget that shows the SSID) but many routers by default will have both SSID's the same, making it less obvious what band you are connected to. I also use an app called "WIFI Prioritizer" (author Robert Botha), which will allow me to connect or re-connect in the SSID order I specify: i.e. when I get home I will connect to SSID "Blah" (2.4 ghz N because it has the longest range). Every 5 mins (you can specify), it checks to see if my SSID "Blah_5Ghz" is in range and will switch to it if it is (you can also set signal strength connect and disconnect thresholds).
Anyways, I probably can't help further but am following this thread with interest. Good luck!

My Phone is packed with tools like Wifi Analyser, InSISDer etc etc atm
I always separate 2.4 and 5ghz networks to be able to see exactly what's going on but thanks for the heads up :good:
From further investigation and thinking, and with your suggestion about stronger signals;
Thing is, AC routers are more or less all simultanious routers.
That combines 2.4 and 5ghz signals for higher transfer speeds.
I think in there lies the problem when drivers are not 100%.
In theory 2.4 signals are stronger then 5ghz signals and have wider range.
But in testing I made sure that I was in the same room and no more than 2 meters away from the router.
when testing it showed equal signal strength up to -20 so really strong signals.
Therefore I concluded that N on 2.4 whas equally strong as 5ghz and then again I isolated 5ghz SSID so that's not it unfortunately.

I promised to stay away but I can't resist!
Have you tried some of the more generic troubleshooting tips (on the home network), such as trying with no security or lesser security (WEP) to see if it still reconnects at the lower (N) speeds? I realize that usually that test is of course for a more basic issue than yours but maybe the G2 has trouble handling security overhead.
Some devices and routers just don't like each other (as many know), but 4 different routers...?! Gotta be the G2 side, as you've surmised. Wish I knew someone with an ac router so I could test myself. I'm debating on getting an ac router but you've got me spooked! (kidding/teasing)

Well haven't tried lower or no security.
When I have the chance (aka the wife is away and not *****ing about wifi not available ) I'll sure try that.
But I don't think that WEP will be an option because AC requires AES protection if I'm not mistaken.
But really do not be afraid to get yourself an AC router hehe.
No honestly, I've tested 4 routers with:
AC Capable:
HTC One. Goes all the way to max isp speeds. All the time, no issues
LG G2.
Not AC Capable.
IPhone 5. Max speed at 5ghz (constantly tested) is ~90-100mpbs.
HTC One X. Max speed at 5ghz (constantly tested) is ~70-90mpbs.
So even if your hardware maybe not be capable of AC speeds you still get excellent connections
Oh and for the record.
Here's my personal listing of the hardware I've tested. From best to well not so good.
1. Netgear R6250.
Excellent constant speeds. No drops whatsoever with around 6 devices connected. Excellent range!
2. Asus RT-AC66U
Shame Asus introduced a new wifi driver some time ago which doesn't perform that well. Constant speed drops.
They know about it but thusfar no solution.
When you get this one, stay on old firmware for now!
3. D-link 868L
Real looker this one. Can be put in plain sight in the room like a picture frame :silly:
Great constant speeds, but some drops here and there.
Excellent range.
4. Linksys EA6700
Linksys is sold to Belkin by Cisco.
Up to now I have never seen anything good coming from Belkin!
What a piece of crap.
With a really thin wall between router and phones coverage went down more dan half. Hell even when distance less than 2 meters away coverage was about -45.
Do not get this crap!

I wonder... the wireless N spec (not sure if also AC) calls for devices and routers to have a 'low power mode', which may or may not be enabled in routers and/or phones (e.g. GS3) by default. According to some article I read, newer routers may go into a power saving mode if it detects low traffic and supposedly ramp up when the traffic increases.
Possibly it doesn't ramp up fast enough when a new device connects and the device mistakes it for not having the highest speed (AC) capability. Might explain fast speeds after router bootup but not later. If there is any truth to that (no clue here), it might speed itself up either by testing with a larger file or seeing if the "2nd connect" condition changes while say, streaming videos from the PC to the Xbox or watching Netflix on the main TV. Certainly, either would be considered high traffic and if there is no change to the 2nd connect, well -- there goes that idea.
Is there a wifi power saving mode on the G2 like there is on the GS3? (i.e. dialing *#0011# to turn it off).

Good point!
Well, there is a setting in wifi, advanced to minimize use of wifi when screen is off. Sounds like a power save mode to me.
But, just tested it and that makes no difference.
With that setting deactivated on the G2 still at first boot AC speeds and when I switch off and on wifi I still get N speeds max.
And besides that, on the Asus router there's a setting called "Enable WMM APSD". Which stands for "Automatic Power Save Delivery".
I read up on that and the custom firmware guru RMerlin writes about that setting that especially Android devices could suffer from that setting.
So I disabled that a long time ago.
On other routers I couldn't find such setting.
But to iron that setting out I just tested it once more.
First with setting off. Still first connect AC speeds, after turn off/on back to N speed.
Then turned wifi off, enabled the setting and rebooted the router.
But this time to let the supposedly power save kick in I let my Phone idle for 15 minutes so that it surely was in deep sleep.
Then turned screen on, and again AC speeds when first connected.
After that turned wifi off, screen of for 15 minutes. Turned screen on again and once more N speed.
And link speed is always shown as 433mbps btw, which is correct.
There's just some bug in driver code by LG which doesn't work correctly.
I'm more and more convinced of that.
For now I just keep wifi on all the time so that I always get full speeds.
Batt is capable enough so no problem there

Well, there is a setting in wifi, advanced to minimize use of wifi when screen is off. Sounds like a power save mode to me.
But, just tested it and that makes no difference.

I found a tool to test local network speed. It uses two android devices for a p2p test or you can install a server program on your PC. I'll do some testing and see if I can reproduce what you are seeing. Here's the link: http://pzoleeblogen.wordpress.com/2013/08/12/local-network-speed-test-for-android/ and the market link: https://play.google.com/store/apps/details?id=com.pzolee.android.localwifispeedtester&hl=en
And to be sure I understand, you boot your phone with wifi on, AC speeds. Turn off wifi on phone and turn it back on, N speeds. Reboot phone with wifi on, back to AC speeds. Correct?

Thanks for the app!
Gonna test this for sure since I also have a HTC One lying around which is also AC capable
Not 100% corect.
I can do with phone what I want until wifi gets turned off.
Then a reboot of the router is required to get AC speed back.
No need to reboot the phone.
Quite busy atm so don't have enough time I would like to be testing

Between my wife on her laptop, my son on his Chromebook and my daughter streaming Netflix on our Roku, I hardly ever have a chance to reboot the router without someone complaining
Since I haven't rebooted my router in days, from what you are saying I shouldn't see anything above N speeds until I reboot the router. Do you actually have to turn off wifi on the phone to have it drop from AC to N or is it enough to leave the range of the wifi and then come back? And does if turning it off is required, do I have to be connected to the router at the time I turn phone wifi off?
I'll try testing this weekend.

Going out of range isn't a problem as long as you don't have an app or setting on in wifi, advanced to switch off wifi.
As long as wifi isn't turned off I can go everywhere, in&out of range, other routers connect but speeds remain AC, everywhere on every router.
I can reproduce everytime that when I turn off wifi on the phone and back on from then on I only get ~36-40mbps max.
It's like the phone thinks that's max capable speed altough wifi link speed is again shown as 433mbps.
If I have switched off wifi on the phone and back on, on all 4 AC routers I tested all needed a router reboot to gain full AC speeds again.
Oh and maybe a small tip, I always say to the misses at home that there's a small problem with connection so a quick reboot is required.
Up to now that still works

I just did a few tests from my phone to my pc with 100MB data sets. I got between 200 and 260 Mbit/s down both before and after toggling my phone's wifi off and on. Didn't seem to make a difference. I got about 6Mbit up.
So, I didn't seem to experience the problem you have. But try repeating what I've done with this local network app. Maybe you won't have the issue with it that you are seeing on your WAN connection.

Wow and do you really see real transfer rates of 25-30 MB/s to your G2?
I'm using a Qualcomm Atheros based AC-router and my G2 (running latest CM11) hardly goes over 10 Mbit ~ 1,5 MB/s. Weak I know. (Confirmed 433 Mbit link using a wifi app.)
Maybe I need a broadcom-router like yours to see some real AC-speeds.
Thanks for the reply. Take care

WiFi 2.4GHz vs 5GHz Power Consumption

I have been researching on Power Consumption between 2.4GHz and 5GHz WiFi. the reason for that is my Exynos N910C seems to drain so much battery when it's on 5GHz WiFi during stand-by / sleep. And of course drains even more when in use.
My set up:
1. Asus RT-AC87U, WPA2, 2.4Ghz and 5GHz, SSID names are differentiated between the 2 bands, eg. WiFi and WiFi 5G.
2. Router placed on the Ground Floor around the back of the house. My Room is upstairs around the front of the house.
3. WiFi Signal strength: 2-3 bars for 2.4Ghz, 1-2 bars for 5Ghz.
4. Phone is not rooted, everything stock, latest firmware, bloatware disabled, only GMail Auto Sync, and WhatsApp running.
5. Phone has been Factory Reset and even reflashed with the latest firmware.
6. Under WiFi's Settings, I unchecked Smart Switch and under Advanced settings, I pretty much unchecked everything in there.
7. Under *#0011#, WiFi is set to Power Save ON.
This setup drains around 1-1.5hr per battery % on 2.4GHz (logged with Battery Monitor Widget) but 20-30 minutes per battery % when on 5Ghz.
At first I though, it could be because the signal is weak in my room, so I bought RP-AC52 and configured it as an Access Point (not as a Repeater) in my room. Once set up was completed, both WiFi band signal are now at full bar so I went to test it again..... but the battery drain rate remains the same! The phone is just 1.5 meters away from the Rp-AC52 Access point.
I've looked up on articles regarding the power consumption between the 2, they keep saying they should be the same, but it is clearly not at least on my phone.
Could anyone test 5GHz WiFi power consumption please and see if it's just me? Thank you in advance.

Higher frequency always means higher consumption.

I kinda figured that part, but 3x the power consumption vs 2.4GHz? And I'm sure alot of people here with dual band routers prefer 5GHz, but I wonder if they are aware it's such a battery hog compared to 2.4Ghz... or even 4G.

A late answer here but if someone is searching in the thread.
On the 5 GHz band of the AC87U, I cannot seem to get the powersave mode of wifi to work, which would explain why the draining is so high.

My experience of using 5ghz on my Snapdragon, is that it would always disconnect when the phone was asleep, even if I had always on. When I unlocked the screen it would take some seconds, then it would connect again to the WiFi. So I'm only using 2.4ghz now.

I have never had any problems with 5Ghz on the Note 4 Snapdragon. The last time I checked I think it drained around 1%/hour, maybe less. The fact I'm using FreedomPop on it though does really hurt the battery for obvious reasons (constant VoIP connection).
I wish Google Apps were less aggressive though. I have my old Optimus 3D as a backup phone with an extended battery and gets 14 days WiFi off, 7 days WiFi on with Google apps signed out, only a couple of days with it signed in.

Same. I guess you know by now why that happens. Reasons are DHCP timer, AP balancing, server side software bug, interference, ARP flooding and Wifi Multicast.
I have spent past few weeks scouring through the internet and finally learned about them all one by one.
