My shiny new PiPo U8 has terrible WiFi, and it can only see the router within a couple of metres. Things improved when I set the router to 5GHz. Before that it was around half.
The tablet is in an all metal chassis which seems like an oversight. However, I find it hard to believe the company would release a tablet with such poor wireless performance.
Is it likely that a firmware update could improve things? I think I've read of such things before.
Thank you
Do you have that problem only with that router? have you checked with another wifi source?
If you have landline wireless phones at 2.4ghz they can mess some wifi adapters as well, check that.
it can be due to a miss connection of the wireless antenna inside the device, there are many possible causes.
Also it can be related do kernel/driver issues on your device, that would be solved by some mods.

Same problem at work. Earlier all the guys with Android phones used WiFi Analyser to show the local WiFi networks. They each got over a dozen and the main one was at -90. My tablet got the same network one at -65 and no other networks. Turning the tablet could add or loose around 5 units.
I suspect it may be a badly connected or badly positioned antenna. I've been trying to find out how to open the tablet up in order to check. Apart from this major issue, it seems like a great device and a real bargain. Elsewhere online there are reports of very good WiFi performance with this tablet.
5 units as in network strenght or 5 units of visible APs?
You know that -65db is actually better than -90db right?
Check if your device is at 2.4ghz Wifi band, and not at 5Ghz as most of the public wifi router are 2.4ghz.
Yep, the antenna wasn't connected.

there's a setting on the phone which you can choose 2Ghz, 5Ghz and automatic. choose automatic.. if it doesn't work reset your modem and press the WPS.
Unfortunately some tablets are designed poorly where they impair WiFi/GPS/3G signals. A prime example is the Asus TF300 tablet.
Try using some apps in the appstore like Wifi Booster
Hmm, I've already answered this. Does no-one read topics any more?

Hey at45, I also took my u8's back off tho check the antenna. It was connected and while the back was off it got great reception. Now to my question, just to be sure the antenna is the small co-axial cable coming from near the power button and going to the area by the speaker, correct? Also does anyone know where I could get a stick-on antenna that I could maybe mount on the back and connect to my antenna lead? I think this would turn this really good tablet into a great one.
I do realize you've already answered this, I was hoping for some insight on the external antenna notion I had
For me wifi is medium to good - not as good as the laptop but not as cruel as some others described it - so there might be different versions.
If you're already as far as attaching an external antenna, why don't you cut out part of the cover and replace it with some nice piece of plastic? Might actually look better than an external antenna...

Hi everyone!
Is it possible to improve the wifi antenna of my nexus s? With my last nokia it was possibile by salding an extra copper wire, is there any similar mod that I can do on it?
Thankyou..
not 100% sure but the antennas are in the back cover along with the nfc chip.
If you remove the back cover, you can see the connector.
The connectors are for the nfc chip

Improve Nexus S WiFi antennaArrow
I have just bought my Nexus S and am experiencing a weak wifi signal. I normally get 3 bars on all other hardware in my bedroom but am only getting 1 bar which occasionally goes up and down to 2 bars. When I am 3 meters away from the Wifi access point i only get 3 bars out of 4. All my other hardware gets full bars. When i am 6 meters away from the access point I have only 2 bars showing for wifi.
The wifi signal icon seems to fluctuate alot. Does anyone else have a similar problem?

I always thought that these connectors were for a power mat to recharge the battery...wow I'll go to bed smarter tonight !!
First and foremost bars don't mean anything really. The signal strength typically is better but what matters is the SNR (signal to noise ratio). This can by typically improved by allowing your router to switch channels automatically (from the default 6) to find the most open one. Adding your own antenna is a bad idea and it likely will make the problem worse. Those antennas are precisely designed (exact configuration) for that ranges of frequencies, adding wire will ruin those characteristics.
With GB the wifi signal was completely awful...but now with ics wifi isn't that bad....I'm not having a lot of issues now...
Sent from my Nexus S using XDA
I haven't seen any difference in wifi signal between GB and ICS: in both of them I get 1-2 bars while my ipod gets full signal. BTW it isn't a good idea to mess up with your phone's antenna.
Most probably it is not.
WiFi antennas on theese devices can even be SMD only (trying to improve is waste of time), or "copper plate sticker" type, ussualy stickered on the internal back cover.
I've been messing around with the second type on crappy chineese WiFi phone - I've added a tiny connector used in mobilephones and connected simply a piece of coax wire to make a dipole. After few changes signal finally got a bit better, but also because in original it was really poor.
If there is a sticker-type antenna, it is theoretically possible to change antenna quite easy. In practise, you will hardly get it better because you can't just put some wire in and done (well, you can, but it will be like wining a main prize in lotery if it gets better). The wire should have right size, right shape and must be on right place. And milimeters makes a difference there, so have fun
Most likely it can get better only with some kind of external antenna, but you could hardly use your phone as mobile then
Easiest way to tune-it-up could be disconnecting the original sticker and connecting a flexible internal notebook type of antenna, but even that will probably be too big to fit inside - it must not overlap another antenna. And that's not the only rule.
Even if it does not overlap anything, it can interfere with other circuitry or Tx-devices. Bluetooth works on almost the same frequencies as 2.4GHz Wifi, for example. It's a piece of science theese frequencies, actually
I'm absolutely NOT thinking of trying to tune it up on my LG O2x, coz I know it won't be better
So my phone is useless for controlling my RC AR Drone then?
Wifi signal is crap, I'm pretty handy with electronics but I've read that even the chipset they've used in the NS is rubbish... Does anyone know which reasonably new handsets have good wifi range? My old N1 was pretty good but it's just too old.
if someone can confirm that it's the antenna and not just a sh*t wireless card then i'll have an attempt at replacing it with laptop antennas.
A little question, it won't be easier to improve the antenna of the WiFi router, instead of the mobilephone's one?? You can do that simply, by putting a can on that antenna (Search on google for the tutorial, it really worked for me).
Regards
Hmm.. I think you can.

Check the Battery Cover, and you will find that. But it's not sure
Wooooow Nexus S have WiMax
There's definitely something wrong with the Nexus S 4G's wifi. I have to be next to the router to be able to use the wifi. No other device, phones, tablet, notebooks, etc has an issue. Odd that others are having the same issue.
Did they forget to connect the wifi antenna?
just upgrade your phone maybe? and your antenna is somewhere in the back.
I found that the WiFi on my NS went to **** after upgrading to JB.

Why is it that the wifi signal strength is better on my laptop than on my phone?
I have noticed this for nearly every device I have owned. The laptop will always seem to catch a better signal than the phone, even though they are both in the same position, same network, etc.
Is there anything I can do to boost the signal range of my phone?
(no I'm not sticking an antenna on it)
Interesting - I notice the complete reverse. My doubleshot has stronger signal to my wifi router and for a longer distance (of about 5 feet in my driveway) then my laptop.

Out of all the different phones I have owned, NONE have been able to catch wifi signals as good as my laptop
As I speak right now, I am connected to the same network with both devices. Laptop shows a good signal, while the phone is showing a poor signal, and even disconnects at times.
Interesting. I guess logic might wanna tell me that a laptop would have a larger/more powerful radio chip, or whatever it is that receives the signal... and that has basically been my experience, my laptop can stray further away from the router. But perhaps it depends on your hardware?

Well, my laptop is about 2 years old and beat up, compiling kernels is killing it.
I wouldn't be surprised if the wifi chip suffered some damage from how many times its overheat and shut off.

I have this same problem, out of all my devices my Doubleshot is the worst at picking up a wifi signal. This includes two other low end Android phones, the Droid Eris, and the Huawei Ascend. On my Ascend I can pick up my neighbors wifi almost anywhere in my apartment, even better than my laptop, but on the Doubleshot I can not pick up the signal at all unless I am outside right next to my neighbors house. I wish there was a fix for this issue. Even at school where the wifi is very strong, I can only pick up a weak signal that disconnects from time to time on my Doubleshot, but my Ascend never had that problem, it always received the signal strong and clear.

My laptop is nearly 4 years old. Runs a Centrino chipset. Maybe that explains the better signal it catches. Either way, I've never seen a phone outperform a laptop in signal strength

lol - you should come by my house. Sometimes (I posted it in a thread a few months ago around here somewhere) I use the doubleshot as a wifi bridge to my router to make up for the inadequacies of my laptop wifi abilities, or for my desktop that has no other means of internet connectivity.
It seems I represent a minority (of one!) in this... i dunno. I've been excited about how well it works out, and am quite surprised (astonished even!) to find everyone else singing a different tune.

Yea, seems like you're the only one. By the way, if your laptop is overheating from compiling, you're doing something wrong. No laptop should overheat, even under full load, unless you have blocked vents, or you're overclocked.
Lol, unless it's choked with dust, has no compound between the processor and heatsink, the fan doesn't work and it relies on an external cooling pad for all of it's cooling air circulation.
Half the usb ports are burnt out and no longer function and the speakers stopped working a year ago. Since the audio out jack has stopped functioning.
I'm pretty impressed with the fact that it even still turns on, let alone being able to actually do anything with it, but, I'm hoping to get a full blown linux install on the doubleshot and thereby circumvent ever having to purchase a real computer again.
I'd grab another laptop, but, i'd rather invest my limited tech funds into android hardware and write off real computers entirely, and given the capabilities of the doubleshot and future android devices on out this is no pipe dream - the only thing between me and realizing that goal is the knowledge to make it happen, a gap that shrinks daily.

hi
I got the dreaded unable to scan for networks. but I found if I flex the phone near the top or drop it from around two foot i can get the WiFi to work.once working it stays working for a good while.its trial and error.ive taken the the cover off around the camera and straightened the pins
but i still have to flex or drop it.I know how crap HTC WiFi can get.Is this a common complaint.
Thanks
Mine locks pretty easily. Could it be that your wifi source is far?
Is it the same with every where or just one particular wifi?

It works ok once on.top edge drop is the most effective at getting wifi on.
Bases on how u describe it would seems like it's hardware related. There is a thread where they discuss about placing foil to enhance the signal, some gave good review and some were skeptical and discourage it. U could try to experimental with it.
I did had wifi issue but the problem lies with the router. I am running a bridge repeater where I would loop on obtaining IP address, setting static ip solved it.
A few troubleshoot I would suggest, setting static IP or trying different rom(cm and sense).
But if it's hardware related then there isn't much u can do.

Thats the road i started on.rooted the phone and many versions of android.renamed the file in the wifi folder also.does look like hardware.
Was just a pure fluke.son was playing a game and dropped it.not too hard.previous to it stopping it was perfect.cheers anyway.
Hi everyone,
I've got a ME301T here having kind of a weird issue.
What's happening here is that everytime I try to connect to any WiFi network, it gets stuck on "Connecting..." and then goes back to Saved, secured with WPA2 - like if nothing happened. I also noticed that the WiFi signal of the specified network gets to one bar when if was full a second before, everytime, at the moment of "Connecting...".
So what I've tried:
I've flashed to 10.6.1.38, no success.
Downgraded to 10.6.1.27 as well, and tried x.x.x.29 also.
All downloaded from Asus.ca.
No success still.
I've tried different AP's every possible securities (and also none). Always the same.
I also tried to put a static IP to see if there was somehow a problem communicating with DHCP, nope. I've shut down the DHCP server, made a MAC reservation for that specified device, nothing. And so on.
Anyone have an idea?
Thanks!
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
Which channel is your router on? If 13 drop it lower.
Thanks to you guys for your answers.
I've tried channel 10 down to 1, also changed bands from both router and tablet (2.4, 5, auto), and so on.
All the same.
Do you think a flash to CM would help?
Thanks in advance.
No idea? Thinking about opening it to switch the WiFi chip, not sure if it's a pain in the a** to open those kind of tablets tho.

Fairly simple - just be aware they have some glue so heat with a hair dryer to melt a bit.
It does sound like a hardware fault.
Alright thanks mate, I'll leave an update on that.
Does somebody know where I could find that specific chip, and what would be the normal price? Does not seem to be that common at all.
Thanks.

Wouldn't it be more comfortable to go for a 'new' logic board?
http://www.ebay.com/sch/i.html?_fro...c+board.TRS0&_nkw=ME301T+logic+board&_sacat=0
Chip coudn't be much cheaper if you ever find one single; and if you are not the solder crack, you might have difficulties to unsolder properly (I myself messed up every single attempt of desoldering a baseband/wifi chip).
Would be a good idea. I'll go on with that I think, since the price doesn't seem to be that high.
Thanks!
Minor diagnostic help
My customer's ASUS ME301T / K1000 connected just fine to a free wifi hotspot at a bank, but not two fast food joints or my own.
At another web page's casual observation, I tried the laptop sitting right on top of the router. Literally touching the two together. It WORKED!
Even two inches didn't allow eh tablet to connect.
Possibilities:
The bank has a 5ghz signal where all the others have 2.4 and the tablets antenna is shot (or very nearly so) thus connecting only when in contact.
A 5ghz router runs $45. A possible fix if you can test with one. I don't have one and don't relish shelling out $45 for a failed diagnostic.
Just wanted to share these two observations. Maybe yours will respond similarly.
A figure a bank might have spent a bit more for their hardware and it had dual band capability.
Hey guys,
I've changed the logic board. No changes. All same.
What now? Is there another hardware part directly related to WiFi control?
Thanks again.

I just made the tablet touch the router and it DID connect.
I am just about frustrated about not giving it a shot before. Damn.
Thanks!!
Now that doesn't fix the issue of course since I'm not sure if there's a way to fix that.
Is the antenna the actual frame? Would it be a connection between this and the board? What to do?
Follow up
The user was willing to take a chance on my being right and risked his money instead of mine.
Got a refurb Cisco dual band router from Amazon for $33 and hooked it up.
The tablet connected without issue.
The 2.4gHz antenna was shot but the 5gHz was strong. Thus, the bank network working just fine.
The router is an easier fix, but swapping out the antenna MIGHT work. I ain't gonna try given the lower cost and almost no hassle of the dual band router replacement.
Hello everyone,
Is anyone of you experience terrible Wi-Fi performance as well?
In our house we have one main router on the ground floor, one more in the 1st floor (no mesh) and an access point in the attic for smart home devices.
When I'm in the garden I can only see the access point and the ground floor router. When I'm connected to the ground floor router the signal is very bad and keeps on disconnecting even though the distance is maybe 15 meters with only one wall in between. I cannot even see the network from the first floor router.
With my OnePlus 9 Pro I was able to see and connect to it, even though the router is on the other side of the house.
Another thing to mention is, that with the OnePlus I could see 10+ networks from surrounding neighbour's and with the Samsung it's only 2.
Im quite happy with the device, but this is really bothering me. I'm not using some crazy case or sth, just the Samsung clear one.
Thanks for reading, any thoughts?
You didn't say if you was on 2G or 5G? Have tested both? What Routers are they? Hard to help without more details about your setup. I have a Netgear AC1750 Router and 2G is crap at around 50mbps on Speed Test and 5G is much better at 250mbps. But it's a single story house with just the sole Router at one end.

I have separate networks for 2.4Ghz and 5Ghz. 2.4 is better for range and my internet is only 50mbit so speed doesn't really matter to me. Main router is a fritzbox and the second router is from some cheap brand. The setup shouldn't really matter though because it is still working fine with my OnePlus.

That's still kinda vague. What router models are they? Also, if you're running multiple routers, you're going to have problems. In a non-mesh environment, the second router should be configured as either an access point, or as an extender.
You could also be having an interference problem. Either between your routers and AP or from external interference from any neighbors' networks.
In any case, you'd be better served by swapping out your current equipment and switch to a mesh system. I use Google's Nest Wifi with one router and three mesh access points. However, there are several other mesh systems that work well.

Thank you for your comment.
The main router is a AVM FRITZ!Box 7590 AX (Amazon) and the secondary is a cheap Tenda AC6 AC1200 (Amazon). Having multiple routers in a a non-mesh environment shouldn't really be a problem. The Tenda is connected via LAN interface, providing it's own network with its own SSID. It's only for a few devices very close by.
I know there can occur problems due to interferences, but I didn't think it was a problem because the Samsung is the only device having issues. I can try messing with the bands, but honestly I don't think it's going to change anything.

Your setup overly complicated. You are essentially running three SSIDs (One for the FRITZiBox, one for the Tenda, and one for the attic AP). Either reconfigure the Tenda as an access point, or pull it out completely. The problem seems to be the handoff between your primary and secondary router. Your primary router should be able to handle the 1st and 2nd floors easily.
Another question. How many smart home (IoT) devices are connected? The Tenda is capable of only 20 devices. Since the Tenda is upstairs, it's going to have better range than the downstairs router (there is a reason why people tend to place antennas higher up). The AP in the attic is not a router and if it is connected to the Tenda via LAN, the Tenda may be running short on capacity. Since it is higher up, your S22U is probably trying to connect to that device.
The way I see it, you have three options:
1. Install a mesh setup. You have one router, with two mesh points (one on the 2nd floor, one in the attic) running one SSID on both 5GHz and 2GHz bands.
2. Remove the Tenda and move your AP to the 2nd floor. The AP can easily handle the smart home devices, and provide WiFi to the second floor and attic. It will also reduce you down to two SSIDs.
3. Remove the Tenda, move the FRITZiBox to the second floor and connect it to your internet modem (or whatever device you get internet through) via LAN (you said the LAN is already run between 1st and 2nd floors). Connect the attic AP to the FRIZTiBox (via LAN). That should give you enough WiFi coverage and reducing to two SSIDs.

Running an Asus RT-AC68U router. I get good 5Ghz signal in every room, the basement, the garage and in the car behind the garage.
Not sure what the issue is but it could be your device.
I highly recommend upgrading to a Wifi6 environment if you have a S22 (but not necessarily Wifi6e). The S22's support 160MHz channels which allows for up to a 2.4Gig multi-stream connection with your phone. My phone will connect anywhere from 1.2-2.4gig in/outside my house depending upon where I'm at in relation to my router. My internet is only 500/500, however, I noticed wifi was much snappier with my S22u over my older Wifi6 phone which used 80MHz channels.
