Which wireless N-router connects artemis? Belkin N1 doesnt !

@all,
just havin sold my iphone i am missing synching my mails with my pda over wireless, since my belkin n1 wireless router simply doesnt allow my artemis to connect
so, mind you telling me how you connect successfully?!
- which hardware / wlan access do you use?
greetz

Any wireless router will help you connect with artemis. I have used Dlink, netgear and also linksys routers to connect.
TO connect sucessfully, you need to activate wireless on the router. Then enable wireless in your arte using the comm manager. Once the wireless is activitated, try searching for networks.

thanx,
but i really aint a novice!
I have tried the belkin n1 now for time and time again...it searches, finds the network, asks for the pin...and returns wireless as unavailable again...
this repeats regardless of security settings or anything else i tried
i remember there having been a lengthy discussion on this...just cant find it..
so back to my question:
which hardware does work?
ideally quote your settings as well, please
greetz

have you checked that both the router and artemis are using the same authentication type? WPA/WEP etc
it might be worth checking that your router isnt set to N-Only for connection speed too....cant remember what speeds the artemis supports but B or G are most likely and maybe your router would reject the connection if it's the wrong type...IIRC the 'N' spec is still in-progress so not widely supported yet

Try a D Link DIR-655

You are not alone!!! I bought a Belkin N1 Vision in December to replace an ageing 3Com router and no matter what I tried I couldn't get my artemis to work. Even without any security. Finally sent the Belkin back and got a D-Link DIR-655. It works like a dream. Connected with no problems at all.

Darn, that confirms what i thought for quite some time - anybody intrested in owning an N1Belkin!
Just doublechecked with an old netgear--and it connects right away...
thanx for ur help!
now could we widen the length of compatible routers, pls.?!

I use a sitecom 300N router and my artemis connects with it without any problem.

Netgear
Hi, I use a Netgear WNR834B. No problems using WiFi with Artemis.
Setup; WiFi up to 270 MbPs, region Europe, channel 6 broadcasting and the strongest encryption for security.
With all of the ROMs i have used, there were no WiFi issues.
Regards

This may be stating the obvious, and I apologize if it sounds stupid, but has anyone checked for the "wireless mode" on the router ?
Just ensure the router is on "mixed mode", i.e. it supports b/g/n connections...
Hope this helps...

hmm I also have problems with SMC (SMCWBR14S-N2), mixed mode, but not connect with Artemis.. my notebook connect without any problems.

had the same problem with n1. tried and tried last night with luck, removed all settings on artemis dissapointed. gave it another go this evening after booting system up and connected okay after putting in password.
just double check all the router wireless settings and any security settings you have. save any changes and restart the router.
hope this helps

Well done getting it to work. I thought I tried everything! Perhaps it was the restart that did it. Too late for me to confirm. My Belkin went back to be replaced with the DLink 655. Good router but does slow down with time and needs a reboot every now and then.

[Q] Wifi randomly disconnecting

An issue I am having is:
I will connect my phone to wifi it will connect fine and tell me I am connected.
I could then later on go into the market and try download something I will have wifi bars but the item will pause download. I then come back out to check if my wifi is still connected and it will say authenticating but doesnt change so I then turn the wifi off and back on. It connects again this time when I go back into the market to download something it works fine.
Anyone else have this issue?

Hey guys still having this issue where my wifi looks like its connected but when i go to settings->wireless&networks-> wifi status will say authenticating with wifi.
It only happens me in my house with my router which is a zyxel router doesn't seem to happen in my parents house.
Is there anything I can do to stop this as its really annoying?

Try changing the authentication type of your router's settings. And if you use MAC security for your wifi, you can disable it.

Well it depends on your router but generally it's under Wireless->Security settings. Mine is with WPA-Personal authentication and TKIP algorithm.

Ok just to update this I have resolved the issue of my zyxel router by changing the security type from wpa-psk to wep.
Wep isnt as secure as wpa-psk but it suites consoles and portable devices better. Since I have changed I havnt been disconnected from the wireless.

I would say that your router has a problem with wpa authentication, I wouldn't recommend a wep authentication. If your wifi signal can be detected from the road where you live I could hack into it in about 10min and many other people plus there a custom antennas that can be made to detect signals and get better range etc.
I recommend you get a better router, something from netgear or belkin would do the job to keep your wifi safe and use wpa+wpa2 together with tkip+aes encryption.

[Q] 5 Ghz WiFi impossible on Linksys wrt610n

Hello,
I cannot connect to my AP on 5 Ghz
It sees it, it asks for password, but then disconnect and reconnect endlessly
Any idea why
Cheers.

One X does not support 5GHz wifi. I see only 2.4GHz in official spec

Oups, I thought it could as i can see it

Switch your router to 2.4, and it will work

I thought it was 2.4ghz only cos of the specification too but i can connect to my 5ghz frequency on my Netgear WNDR3700.

I can see and connect to my Netgear 5Ghz WNDR4500 no problem at all.

You guys can tell me what parameters do you use for your 5ghz ?
Thanks.

My router is fairly new, just bought it 2 months ago. I didnt change any of the settings, just plug & play. Even didnt change the router password.

The problem is with Linksys router's wireless .
even in my house we used to have a Linksys router , kept on disconnected when over 3 devices are connected to it , keeps on disconnected every 2-3 minutes really.
changed the router , and everything is smooth now

WIFI Channel 44
WPA2 AES encryption
Up to 300 Mbps speed setting
5Ghz a/n network types.
That's all the settings that i've configured, although it works out of the box with stock netgear settings too.......

I have tried to double check this spec on the HTC offical website and it does indicate this phone supports WiFi 5Ghz, as it is with Wi-Fi 802.11 a/b/g/n
htc.com/us/products/htconex-att#tech-specs
however, i have tried to link with a DLink router, DIR-857, and it sees the 2.4Ghz SSID and could connect without any problem, however, not able to see 5Ghz SSID though, i have also tried to set no security and with different channels but seems not have any lucky to this.
i am wondering is there any particular setting to the phone or router double checked with customer service but seem not really help, only ask me to change and try with another AP or router.....

I'm connected to my 802.11a AP with no problems at all. Ditto for 802.11g. I don't have 802.11n here so no idea if that affects it or not.
I didn't need to do anything special on the phone. The AP is a Cisco AP1242AG and it has the usual configuration with WPA2-PSK.

WiFi Keeps Dropping/Disconnecting Through Second Router

First of all, I have internet from Time Warner Cable and it came with a router/modem all in one. Now that was initially set up and that works 100% perfectly with my SGS2. Since I have a weak WiFi signal upstairs in a couple of rooms, I decided to hook up an extra router that is set up as an access point. The second router is connected via a cat5e lan to lan to my main router (home is wired with cat5e connections).
Now on the second router, I have disabled DHCP since the main router is responsible for that. On the second router, I set up a different SSID first to test it out. All wired and wireless connections worked great through my laptop/Xbox 360, PS3. My SGS2 connected fine as well and worked.
Now the issue is that the SGS2 "drops" the WiFi after some time. Sometimes it happens after 5 minutes, sometimes 30 minutes, etc. Even with the SGS2 right next to the router it happens. Meanwhile, my laptop stays connected the whole time.
I can't seem to figure out what the issue is now. I've reset the second router a couple times and set it up all over fresh but it doesn't fix the problem. Seems to be a problem with my brother's Sensation as well. Is there something with Android and access points or going through a second router that causes issues? Any other settings I'm overlooking? SGS2 connected to the main router stays connected until I turn WiFi off. But to the access point, it drops out after some time.
FYI: Second router (access point) is running DD-WRT firmware.
If you need any other info, just ask. I'll be home from work in a couple hours. I've been messing with this for the last 2 weeks but nothing seems to work. Please help! Thanks.

Hmm thats very odd. Im running a similar setup as you, except my main and 2nd router connect via 5ghtz N.
Have you tried statically your phone with an IP address then modifying your main router (that gives DHCP) to reflect that IP is permanently assigned?
edit: to hard set your phone...settings-->wireless and network-->wifi settings, then menu key and advanced. Just fill in the IP and gateway info, and obviously use something in your DHCP subnet. You'll have to look at your DHCP subnet, but you'll probably use 255.255.255.224 as your mask, and use your gateway (your main router IP) as your DNS.

Try giving your phone a static IP from your main router. Also make sure that you adjust your phones wifi settings under advanced settings so that your phone stays connected to wifi during sleep. Hope that helps.

Well my phone is getting the same IP address each time, whether I connect to the main router's SSID or the second router's SSID. But I will try this static IP. One problem is that I don't know how to find out my DHCP range. There's nothing in the main router's settings about the range. The second router has an option to set the IP address range for DHCP but the main router doesn't. See attached image.
I'll try to set the static IP around what the IP addresses of other devices on the network are since I don't know the exact range. Let me know if I'm doing this wrong. Not sure what you meant by 255.255.255.224 there.

The static IP didn't make a difference. Still keeps disconnecting/dropping after some time. Meanwhile, the connection with the main router stays connected. Don't know what else I can do. Seems that my HP Touchpad running CM9 stays connected to the second router without dropping. Don't know what's different about that from my phone.

Does anybody have some instructions on how to set up the second router as an access point? I'm pretty sure I set it up correctly but apparently there seem to be some issues. People who have a similar setup that can help would be great.
Main router from cable company with built in modem where internet connectivity comes from is downstairs. Connect cat5e from LAN of main router to LAN of second router upstairs. Second router set up as access point for better WiFi coverage upstairs.
2 options for second router: DD-WRT D-Link DIR-615 or D-Link DIR-625.
"Could" buy some other recommended router for this and try that if needed, but would definitely prefer to use what I have and get this to work.

This might be completely off but I had a similar issue with my SII when connecting to 802.1x networks at my University. I downloaded this app called wifi fixer and it resolved the wifi connection drop for about 90% of the time. Give it a shot, it might do wonders for ya.

First you need to find out if your router is supported. According to the DD-WRT database, the 615 is, the 625 is not. But there are several revisions of that router, so you need to find out what revision you have. It should be on your label.
Router database
Then you need to decide whether you want a repeater, an access point, or client bridged. You can read the differences in the DD-WRT wiki found HERE
Then you need to find the best build to flash to your router. I suggest reading the overview of the 615 found HERE. Read the ENTIRE thread. If you flash the wrong version to your router, you WILL brick it.
Then flash the appropriate firmware, set it up, and youre done. Youre going to have to do some reading.
edit: I would also suggest downloading wifi analyzer on your phone and do a site survey of available channels in your house. Most likely you WILL have interference from neighbors. Youre going to want to hard set your channel to the least congested channel, either 1, 6, or 11. Once you get DD-WRT set up on your 615 you can do a site survey within the router as well.

change the channel on your router to 6 not 11 i had that issue with our second router and actually my nook color. Depending on the router it should be under wireless settings.

The only reason to use one over the other is congestion. Thats it. And you want to use 1, 6, or 11 because the DIR615 has N capability, and you need a wifi primary channel to use N. Theres only 3 primary channels...1, 6, and 11.
edit: Heres a technical overview of N: CLICK ME!

I have actually done all that. The DIR-615 is an E1 version and I flashed the correct DD-WRT firmware on it. I followed a tutorial from the DD-WRT website to set it up as an access point as well. My laptop works perfectly with it. Just my phone keeps dropping the connection from it. My main router is on channel 11 and the second router is on channel 6. I also tried channel 1 but it didn't help.
I might just to try set it up as a second router on a different subnet than the first router and see if that helps. Going to try to follow this Youtube video and see how it goes.

Hhmm ok. Well your main router shouldn't have anything to do with it. When it drops does it re-aquire an IP and reconnect? Honestly if a reboot of the router doesn't fix it and your laptop doesn't have the same issue, its pointing to the phone.
Maybe a factory reset?

It reconnects when I unlock the phone. Sometimes I have to reset the Wifi on the phone. Have set the Wifi connection to never sleep. My brother's Sensation was doing this as well. I'll have to test it out on his phone and see. I'll probably reset my phone later today and see if that works.

No issues with wndr3700 here.
On your gnex, go to setting gas, WiFi, then press the menu button go to advanced and check the WiFi sleep policy. Make sure it's set always on "keep WiFi on during sleep"

One quick thing to look at, that seems to pop up now and then, what's your DHCP lease set to? Setting to '0' (that should be forever) doesn't work as well for some chipsets it appears. If you just have bad luck getting/keeping a lock on your router, try changing the dhcp to something else, 2 weeks ish? Play with it.
Might be something else entirely, but after having seen this 3 times now, it's worth a bash.

TKS for replay...seems netgear wndr3800 not allow change the dhcp lease set...there are not option about dhcp lease set...and as my custom...i have set the gn as a static ip...so it may not be effect to the dhcp lease set...both wnr612 v2 or wndr3800...all of them not have option to set dhcp lease...

What type of connection are you using on the wndr3800?
2.4ghz, 5ghz?
And what channel, since you have two routers, make sure they're on different channels and opposite, set one to 1 and the other 11 or 6.
Also what type of security? wep? wpa2?
Try using 2.4ghz, i found the 5ghz isn't very strong/good with gnex.
Also you can try with NO security and see if it works better.
...
worse comes to worse, reset your wndr3800 back to default and regular dhcp no static, no custom settings for anything and go no security on wifi or go wep.
...
Also, since you have 2 routers, you have them set so that only 1 is doing the dhcp and the other is turned off right? you can't have 2 routers doing dhcp.

Always worked fine with my 2.4ghz 802.11g (can't remember model#) Netgear router. Never had issues with other routers too.

i worked round it by not using DHCP on the phone, change it to manual setting and assign an IP (or keep the current setting) to the device (long press on your connected wifi, then choose modify; for some reason adding new connection only accept DHCP by default). need to do that at the router end as well, edit the lan setting and record the phone MAC address to that IP. someone on another thread mentioned, if my memory serves me right, that GNex can have wifi issue with some routers' DHCP setting, causing it to drop connection when new lease was issued, and this is the reason why i choose not to use DHCP.

TKS,I try it…hope it can work…

the GN can connect to all dlink/tp-link wireless router and never disconnect after screen lock...so i check the advance wirelees setting about three sets include netgear.dlink and tplink...i found the netgear has a few option you can set about advance wireless setting...the other two router have very detail setting about wireless...read the help text...i found the beacon peroid may cause this issue...default value is 100...so i tried to increase the value to 200..oops...the gn disconnect the wifi...and i can't receive any data...just like the email sync,weather sync,and google play push soft install...then i decrease the value to default..the wifi work fine,i can receive any data under the screen lock...then i continue decrease the value to 50/20..nice...no any issue...so i believe is the beacon peroid cause this issue...but the question is the netgear never has a option to let me change the bacon peroid value...so i will connect to the factory...hope they can fix it in the near future...
attachment: what is the beacon peroid
beacons are packets sent by a wireless router to synchronize wireless devices...specify a beacon period value between 20 and 1000 the default value is set to 100 milliseconds...

No issues with wndr3700 here.
On your gnex, go to setting gas, WiFi, then press the menu button go to advanced and check the WiFi sleep policy. Make sure it's set always on "keep WiFi on during sleep"

My main router is my FiOS router, that does all the DHCP, I have one of the ports plugged into my WNDR3700's port (not WAN port), I use the WNDR3700 for all WIFI devices.
I have DHCP turned off on the WNDR3700
Basic Wireless Settings
Both 2.4GHz b/g/n and 5GHz a/n I have SSID broadcast on, and set to Up to 300Mbps.
2.4GHz set to Channel 03, and 5GHz set to channel 36
I use WPA2-PSK [AES] for both radios.
In Advance Wireless Settings, it's all default.
Both 2.4GHz and 5GHz are the same:
Fragmentation Length: 2346
CTS/RTS Threshold: 2347
Preamable Mode: Automatic
Transmit Power Control: 100%
That's it, I do have MAC Address Filtering too, but that shouldn't matter.
Again, everything else is default.
