Deskjet F4140 won't scan on wireless network

I have a deskjet F4140 connected to my home wireless network using a DLink DP301U wireless router. All computers on the network find the printer OK and print properly, but we are unable to scan anything into any of the computers from the F4140. What research I've done tells me that the DP301U just does not have that capability. None of the routers I have found that list the All-in-One units that they will support show the F4140 as an approved unit. Can anyone tell me what wireless router will work with the F4140 and allow it to scan to the network as well as print? Thanks in advance for any help you can give me.

Thanks for the reply Doc. I've been finding that out with my own research. The few that claim to support the scanning functions also do not list my printer as one that will work with them. I have however discovered that there are at least a couple of wireless All-In-One printers that sell in about the same price range as any of the routers that claim to be able to do the job. Given the somewhat limited options, my wife seems to think she can live with having to hook her laptop direct to the printer when she needs to scan something, so for now I guess we will just live with the print only function. If it gets to be too big a hassle, we'll just replace the printer. The F4140 is not exactly a top of the line unit anyway, and we might just end up with something better in the process. Thanks again for your help.

TS1398 this didn't help me at all. out of the clear clue my iPad can't even scan for wireless networks. even when I type in my home wireless network name. my phone can connect to it but for whatever reason my iPad won't. nothing I've tried works. I'm ****

believe me I've tried EVERTHING and my iPad still 'can't scan for wireless networks'. it happened all of a sudden and is really really frustrating. I really don't want to have to drive 40 minutes to the nearest 'genius bar'. I'm about ready to break this thing over my knee. I've even tried the frig trick. it worked for about 30 seconds. and then? nothing. any non sarcastic suggestions?

TS1398 cannot scan for wireless networks

My phone will not connect to home wi-fi. My DH's iphone is connecting fine, but mine won't and it doesn't list any options for network connections. wi-fi is ON. Ask to join networks is ON. Error msg "cannot scan for wireless networks". I turned the phone off and also reset network.No changes....Thanks in advance for your help

I have had this issue of not scanning for WiFi networks as well. I just tried the following, and it has worked for me, at least for the last 12 hours or so:
1. Turn ON Airplane Mode
2. Power off the phone normally: Hold power and home keys for 6 sec, then swipe the "power off" slider.
3. Waited 1 minute
4. Turn on phone, wait for it to reboot itself
5. Turn OFF airplane mode,
Immediately, all WiFi networks popped up, and I could select my home network with the same saved password etc.
Of course, this might not work for every case, but it's easier than a phone restore and worth a try.

Cannot scan for wireless networks

Since last night has been connecting to 3G and wi-fi on and off, and now won't find the wi-fi at all, circle keeps going around. try to enter it manually but it says it could not scan for wireless networks. have tried resetting network settings, turning the phone on and off but nothing works.
Did drop the phone yesterday but am hoping i havent broken some internal part and that someone can point me in the right direction!!

It sounds like you DID break something, or at least loosen a connection when you dropped it.

Scan for wireless networks doesn't find Airport Express

Help please!
I've been trying for days to set up my Airport Express.
When I do the scan for wireless networks, my computer seems to find every network in my block of flats except my AX. I found it once or twice, and then used the AirPort Utility to do the setup. But then it lost the connection on restart. Now the AX connection is nowhere to be found.
Similarly, when I scan for AXs using AirPort Utility it finds nothing.
I don't think it's the AX that's the problem, because I have a wifi blackberry and when I scan for wireless networks on that it finds the AX (although it won't connect). And I don't see how it can be my computer (which is not a Mac) because it finds about 10 other networks.
What am I doing wrong? I'd be most grateful to anyone who could explain it to me in language a 2 year old could understand, because it's all a complete mystery to me.
I use a BT Home Hub for wireless internet, if that makes any difference.
Thanks!

If there are lots of other networks in the area you are probably getting a lot of RF interference.
Can I also add, the AX has relatively weak signal compare to some of the desktop wireless routers due to its size and small power source. If the interference is really a problem, AX might not be your best solution. You should consider upgrade the AX to something more powerful like the AEBS/n. Get the N version so you have a choice of moving your wireless network out of the crowded 2.4GHz band and move it into less populated 5GHz band.
Just my 2 cents.

[SOLVED] Scan for wireless networks at boot

Lately I've been making extensive use of public wifi hotspots (libraries FTW), as mobile broadband is simply too unreliable to give me a persistent (and cheap) connection.
Is it possible to use some combination of netcfg and wifi-select (or similar tools) to scan for wireless networks at boot?
I've already got entries in rc.conf for my mobile dongle and automatically detecting ethernet connections, but it's pointless adding entries for whichever wireless profiles I might use as searching for these and discovering they don't exist just needlessly slows the boot process, whereas running something similar to wifi-select at boot (with a timeout so an unattended boot won't wait for me to make a selection) would avoid this.
* Obviously I could just wait until the system has booted and then bring up the interface I wanted manually, but generally I only reboot my system after updates, and I only download updates at a wifi hotspot, so I was hoping to automate something here.

HP8500A all-in-one can no longer scan thru wireless network but prints fine.

HP8500A all-in-one can no longer scan thru wireless network but prints fine. Have used this device several times over past 2 years on different wireless networks (at home) but usually at some point I lose wireless scan function but maintain wireless Printing. I used to be able to reload the software and resolve the issue but now in this "new network" cannot get wireless scanning to work. Setup software; original software (CD) and current download as well as "Print/Scan Dr" hangs-up at "network check" for hours. Compaq laptop, Dell Laptop, Cell phones and Roku work fine thru network. Scanner works fine with USB to Laptops.

Which model Epsons are they?
I'm assuming you're using Yosemite (OS X 10.10), and that the problem developed when you upgraded from a previous OS.
(Your profile says 10.6.7 BTW).
Maybe the scanning function is not compatible with Yosemite.
You could try a few things:
reset your wifi system:
power down everything: modem, router, computer, printer/scanners.
wait a minute.
power them all up again, in that order: modem, router, computer, printers. Let each power up completely before going on to the next.
try a factor reset on your printer/scanner (if there is such a function). You'll have to check your manual for how. If you do that you'll have to enter the wifi password in your printer/scanner, assuming you have security on your network.
uninstall any printer manufacturer "utilities" that are on your Mac, and try Image Capture again.
If it is a compatible software issue, you could try VueScan, but I've never needed to use it.

Mac Mini - Core Solo - Won't See Any Wireless network

I have a Mac Mini, first gen Intel, Core Solo, that won't see any wireless networks. However, it will see my extreme basestation, and my two airport express devices over bonjour, which makes me think that the wireless device is working.
I've reset the PMU, with no luck.
Any suggestions?

Does an Airport card show in the system profiler?
Is Airport switched on in your mini - the Airport icon in the menu bar should show at least grey bars rather than an empty white 'fan' shape?
With Airport on, when you click on the Airport icon, does it show any network?
If you click on 'Join Other Network' and type the name of the wifi network you run, what error message does the system give?
How far away from the wifi base station is the mini? What kind of structures and environment is it in?
If you move the mini to be in close proximity to the wifi base station, does it show any signal?
When you download a copy of AP Grapher (http://www.chimoosoft.com/apgrapher.html) and run it, what does it show for signals, noise etc?
How is the mini seeing any wifi devices via Bonjour - do you have it wired into your network? If so, the fact that the devices appear via bonjour doesn't mean they are transmitting wifi, nor that they are in range.
By the way, the Core Solo mini doesn't have a PMU to reset. If you used the PMU reset procedure it won't have helped, and may actually have caused problems. The correct procedure for an Intel-based mini is an SMC reset, as follows:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, *making sure the power button is not being pressed* at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.

IPhone 4S - Could not scan for wireless networks - help needed please

Hi
Can anyone offer any advice please.
My 4s has developed an wifi issue. It cant scan for wireless networks My bluetooth is intermittent also.
I have turned it on/off, rebooted, reset all networks, reset to factory settings, set to airplane mode, set to do not disturb - everything and all to no avail.
I am under a two year contract with Vodafone and went into their branch at Merry Hill, Dudley today and they failed to help me saying it was nothing to do with them.
I am at a loss as to what to do. I have not had any accident with my phone and it is still in mint condition.
Can anyone please offer any suggestions on what to do.
Many thanks.

Apple's out-of-warranty policy is a feeble attempt at covering up it's issues and is a clear cut demonstration for their lack of respect for its user base. Their WIFI/Bluetooth dropping issues have been around for several years now and it started within the last 3 IOS updates. Apple engineers acknowledge this problem and don't have a solution yet... this was confirmed at the Genius Bar at their Nashua, NH outlet. My phone is 6 months passed warranty and my Verizon contract isn't up for renewal for another 6 months.
There are a lot of complaints about this (a LOT), yet Apple continues to stick its head in the sand instead of owning up to providing shoddy hardware and/or glitches software. They certainly don't want to be in the business of replacing phones, so they put the onus on us by charging $200 for a replacement... such a deal for Apple!
Apple's support communities are basically useless on this subject with a lot of screwy so-called solutions to work around their flaws. I've seen one fix where you heat up the phone with a hairdryer until the temp warning appears and then refrigerate it for 10 minutes... then BINGO, it's all fixed! Ya right!!!
Resetting network settings, or all settings (including a complete reset) is ineffective and appears to do nothing more than to further upset Apple users once they realize that they have wasted their time following Apple's so-called fix.
I just wonder if or when Apple pulls it's collective head out of the sand will they be able to see that their competition has surpassed them by leaps and bounds. There really isn't any good reason to stick with Apple now-a-days since their conscience passed away. Their competition offers superior technology while Apple continues to impress up with new connector technology and placement of their sockets.
I am finished with Apple and am incredibly sick of their spoon feeding what they want rather than what we want.
The best way to make Apple improve is to provide them with a taste of their own WIFI/Bluetooth offerings by DROPPING THEM!
They have abandoned us and have no problem trying to charge us to replace their flawed technology instead of doing the right thing!

Bummer..my phone quit scanning for wireless networks

in Baja on vacation and my phone suddenly stopped scanning for wireless networks. Got any ideas? My partners iphone works fine. I reset my wireless networks in the settings window. I tried manually entering the network name and pass code. I removed and replaced my sim card. I'm hesitant to synch, backup and reset my phones settings since I definitely don't want to compromise it further. Been there done that.

Here is a solution that might help. I too had the unhappy message of " could not scan for wireless networks". Thinking it was a wifi hardware problem or software problem made me give up until an idea hit me. Maybe it was an app. that was giving me problems. So I deleted an app. I had , which was Devicescape Easy Wifi, and did a reset network setting. This solved my problem. So look at your app. list and delete any wifi app. and see if that works.

Stuck interrupt when scanning for wireless networks (Athero chipset)

I'm working on getting wireless running on my Thinkpad T40 with an Atheros AR5211 a/b adapter. The ath5k module loads automatically, and the dmesg output seems to indicate that it is properly detecting the card:
% dmesg|grep ath
[ 4.767272] ath5k 0000:02:02.0: registered as 'phy0'
[ 5.042780] ath: EEPROM regdomain: 0x61
[ 5.042787] ath: EEPROM indicates we should expect a direct regpair map
[ 5.042793] ath: Country alpha2 being used: 00
[ 5.042796] ath: Regpair used: 0x61
[ 5.478542] ath5k: phy0: Atheros AR5211 chip found (MAC: 0x42, PHY: 0x30)
[ 5.478549] ath5k: phy0: RF5111 5GHz radio found (0x17)
[ 5.478553] ath5k: phy0: RF2111 2GHz radio found (0x23)
I brought the interface up using ip:
% ip link show wlan0
4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether [redacted] brd ff:ff:ff:ff:ff:ff
The trouble comes when I try to scan for wireless networks. I run "sudo iw dev wlan0 scan". At this point, the system becomes very sluggish, and the load average began to monotonically increase. The scan never completes; I left it for 15-20 minutes and cut it off when the load passed 3.5. The load average did not go down after iw was killed. Checking in top, the CPU was pretty evenly split between a kworker process and ksoftirqd, even with the scan terminated.
I've searched around, and while there are all manner of problems reported with getting various wireless configurations to work, no one seems to get tripped up at the scanning phase like this. Does anyone know of diagnostics I could try (or perhaps other scan tools?) to narrow down what is actually causing the CPU to get hammered?

I got a chance to play around with this a bit more, trying wireless_tools this time:
% sudo iwlist wlan0 scan
wlan0 Failed to read scan data : Resource temporarily unavailable
As before, the load average then continues to increase until the system becomes unusable. This would lead me to believe that I have a driver or kernel issue, since that would be the commonality between the two tools.
The other interesting output is this:
% dmesg|tail
[ 280.973316] ath5k: phy0: too many interrupts, giving up for now
[ 280.989985] ath5k: phy0: too many interrupts, giving up for now

[ 281.019983] ath5k: phy0: too many interrupts, giving up for now
[ 281.034543] ath5k: phy0: too many interrupts, giving up for now
[ 281.049984] ath5k: phy0: too many interrupts, giving up for now
[ 281.064543] ath5k: phy0: too many interrupts, giving up for now
[ 281.079983] ath5k: phy0: too many interrupts, giving up for now
[ 281.094544] ath5k: phy0: too many interrupts, giving up for now
[ 281.109122] ath5k: phy0: too many interrupts, giving up for now
Looking at longer tails, this message repeats many many times, interspersed with:
net_ratelimit: 321 callbacks suppressed
With various values for 321. Some interrupt getting stuck would make sense for why the load average blows up, but I really don't know how to fix that ...
I verified on the ath5k site (http://wireless.kernel.org/en/users/Dri … rted_Chips) that my chip is supported:
% lspci
02:02.0 Ethernet controller: Qualcomm Atheros AR5211 Wireless Network Adapter [AR5001X 802.11ab] (rev 01)
Any tips for what might cause a stuck interrupt like that?

IPad could not scan for wireless networks

My iPad 2 was bought in April 2011. And just a few hours ago it suddenly disconnected from my home WIFI.
I tried to reconnect it, but it either kept scanning the network or kept prompting the warning message "iPad could not scan for wireless networks".
My Macbook Pro, iPhone and another iPad 3 were all working fine with my two different WIFI points at home yet only my iPad 2 couldn't scan both WIFI at all.
I have tried to:
1. Reboot IOS (turn it off and on)
2. Take out sim card
3. Reset Network Settings
4 Reset All Settings
5. Restore iPad from iTune
I've called Apple, obviously they had no clues about this problem and they just adviced me to send in my iPad 2 for 1-to-1 change.
This seems to be a common unsolved issue for apple users. Has anyone solved this before?
Now I'm worrying will my iPad 3 get the same issue in future. it makes me quite frustrated

TS1559 could not scan for wireless networks.

Wifi not working on my Iphone. All I get is "Could not scan for wireless networks." Does anyone have a solution to this problem?

If no change after powering the iPhone off and on and/or after a reset which is similar to a computer restart, try resetting network settings on the iPhone at Settings > General > Reset.
If no change after that, try restoring the iPhone with iTunes as a new iPhone or not from the backup but update the iPhone's backup immediately before doing so for later use.
If no change after restoring the iPhone with iTunes as a new iPhone or not from the iPhone's backup, the iPhone has a hardware problem.
