Sandisk WIFI and Linksys WRT54G - Networking

Hi Peeps,
I have searched this forum and the Internet and have found loads of info on problems with the Sandisk WIFI and D-Link routers (54G) and some have found workarounds etc.
My Linksys WRT54G (54g) (mixed mode) is not accepting the Sandisk 802.11b and I wondered if anyone had a workaround or experience of this.
It also makes me wonder that as community hotspots upgrade their routers to 54g (mixed mode) more and more of us are not going to be able to get on with our Sandisk cards.

I have tried on BEF11S4(B) and WRT54G(G) both work fine...
Try update the rom for Linksys Router or set the speed to "B" only and try.

I've been using SanDisk Wi-Fi with Linksys 54G, firmware v1.06, Feb 18 2003 and I was ONLY able to connect after setting channel 6 on the AP. Same happened to 3com 3CRWE7254G PCMCIA card. Don't know why it's so, as at home I am able to use any channel with 3com OfficeCOnnect 54G AP..

Hi Guys,
I have updated the firmware : v2.02.2, Jan. 6, 2004
WOW, the interface has changed and I now have the new 256bit WPA
However, I still can not connect I have tried B mode only .... now available as an option
I do not use WEP or WPA only MAC address. I did read somewhere that a WEP key was needed regardless....
Any thoughts ? ..... cheers

im not to sure about the sandisk wifi card, because i dont have one
but last week i did upgrade my home network to the new equipement from netgear
all my wireless pcs worked fine except for one
make sure the channel is set correctly
mac address shouldnt be a issue unless ur trying to setup a bridge
what got me was the wireless card in the laptop had a hard time switching from the old access point to the new one. make sure ur SSID is set to what ever the access point SSID is
regardless if the access point is set to broadcast or not (means itll send out a signal lettings pcs know how to reach it), they need to match to connect.
none of my pcs require WEP unless i turn it on, but now that im at 802.11g and not b, i think i might turn it on till i take a laptop and start walking around outside to see how far it reaches
hope it helps
-Mario

Cheers Mario,
The XDAII see's the network SSID, and says 'available' when it tries to connect it drops back to available as if it can't get on ... almost as if the MAC address was wrong (I have checked )
When I go home my Belkin 802.11b router is picked up instantly, so I know all the settings are OK.

I found this today
http://www.theregister.co.uk/content/69/35986.html
ita a article on incompatibility between different wifi vendors, might wanna read it really quick
other than that, basic trouble shooting says...
whats the difference between your home network and the one you want to connect to ?
Do both have dhcp setup and working ?
does it not work with web or have you tried AIM, msn messanger, telnet, etc... ?
are you able to ping a server from the xda2 ?
alot of this will oviously be based on what programs you might have installed. not sure if / or what a good telnet program for ppc would be
a ping test might give you a good idea if your being assigned a ip address, but just cant get to a web address
have you tryed changing what wifi standard your using ? on my new netgear, i have the option of b , g , b and g, 108mbps (specific to netgear i think) and 108mbps auto sensing

VARIO Wifi Access points that Do or Dont Work!

Im looking to get the Wifi working on my Vario at home. My current Access point wont connect due to T-mobile's lock out of the 802.11g.
So I can get a Access point that works, I thought it would be helpful to post up your Model with a Yes or No after you have tried all the different settings as posted on the forum e.g. different channels and mixed mode etc.
This is for g Locked Varios only please not ones with flashed ROMs.
Please keep it simple Model YES or NO.
Thanks
:wink:
To Start us off......
Inexq HR054g Access point (NO)
if your Wizard has b only (ROM issue, not hardware) then ANY router which is set to allow g only will fail to connect. yours "should" allow "b" devices to connect http://www.inexq.com/web1/images/product/spec/hr054g.htm
So maybe you have a setting that is allowing "g" only

Router is set to mixed mode, it can see the network but wont connect
Have you got MAC address filtering enabled on your router and forgotten....I did.
Also try changing WLan card settings on your XDA from Best battery to best performance..Make a lot of difference. and many have found theirs connects after this
All turned off any other options
I have a BT2100 wireless router and mini-s, sometimes it won't connect until I stop active sync running on the mini-s ???
3-Com OfficeConnect ADSL Firewall Wireless 11g Router (set to mixed)
Vario will only connect when router set to open access i.e. security disabled. Any other setting i.e. WAP, WEP causes the routers internal DHCP server to fail to send an IP address back to the Vario... or the Vario being unable to acknowledge the router?
Have got a couple more routers comming my way, will post them up when Ive had a chance to test them

I've seen this issue detailed elsewhere but I can't remember exactly where - apparently for some reason the 3com sends back an IP v6 address when security is enabled, which the Wizard can't use.
So far I've used a cheapie Origo wireless router (conexant chipset) and a Netgear D834G (in mixed mode), my Wizard seems happy with both.

Off topic - Wireless - What am I doing wrong?

Pardon me because this isn't entirely a Wizard specific questions although I am able to replicate the problem with my Cingular 8125 (new ROM) 100% of the time.
I'm not a stupid person. I've setup numerous wireless networks for corporations and home users. I always use WEP or WPA and never unencrypted (no) security.
In most situations, the wireless router does NOT supply the DHCP to the clients. It usually comes from another DHCP server on the same LAN segment. Typically, this is a Windows server although it could be a DHCP-assigning device, such as a Cisco router.
PCs have no trouble seeing the wireless network and connecting to it and getting addresses assigned to them. For a while, I couldn't do this on WPA security but upgrading firmware and software on the laptops (usually Dell) rectified this.
With my Wizard, both old and new ROMs, I can SEE the wireless networks and connect to them but I can NEVER get an IP address. It tries and tries and fails and fails and eventually gives up. (Yes, the Cingular proxy is turned off)
Yet, at the airport or other public places with free wireless, I have no problems connecting my Wizard to the access point and surfing away. Thus, I know its not (entirely) a Wizard issue. Of course, these public access points aren't encrypted which could be one of the reasons but I doubt its the only one.
As a test, I just built a new wireless router with a SSID (other than "default") and security turned on (WPA) and let the router act as the DHCP server. Wizard connected in seconds and was surfing away. So the obvious next question is: why doesn't this work when the wireless router ISN'T the DHCP server? Other machines (laptops and such) have no problem connecting to one wireless router and getting a DHCP address from another box yet my Wizard cannot.
I've tested this with D-Link and Belkin wireless routers (consumer-grade).
I've seen other people post that they cannot get their wireless to work on their Wizard and while the fix may not be on the side of the Wizard, I think others may be in the same boat I'm in so I'm hoping that maybe we can compare enough stories to narrow this down so that we CAN use our Wizards wirelessly!

Confusing...
maybe you should try assign a fix ip to your pocket's wifi adapter and see if it would work. or just let the wlan security turn OFF on your access point to see what would happen.
i guess that the network protocol stack is slightly different between a PC and a PPC, which limit the DHCP request route.
I have just purchased the Wizard, aka o2 XDA Mini S, and use it with my Belkin Wireless Access Point (WPA-TKIP Enabled, DHCP & NAT disabled) and Cisco ADSL Router (DHCP Server) without any problems.
I have assigned the Belkin Wireless Access Point a fixed IP address however, but I don't think this would make a difference.
The other thing I found was that the Wizard would not connect correctly to the Belkin using WPA with AES encryption, but switching it to WPA with TKIP works flawlessly.
Well, I suppose its encouraging that others with the same wi-fi routers are getting this to work but its discouraging that I'm having so much trouble!
Fixed IP does work (therefore, its unlikely a Wizard-only problem) but obviously a fixed IP doesn't let me roam from one hotspot (home) to another (work) very easily.
Haven't tried it sans-security yet although that might just prove a point, rather than be a perminant solution. I have tried WPA-PSK and WEP with the same (negative) results.
I personally have found that unless I change the power settings for the WiFi adapter to full power, its hit or miss.
Never have a problem maing connections, geting leases, etc with it there.
YMMV though

prob irrelevent
i found that before i active sync'd. the wireless monitor on my wizard showed a strong signal from the router. then after it synced, it picked up an IP from the servers dhcp fine.
also for lightweight simple security i use mac address filtering on the AP

TyTN and the Linksys WRT54G

Has anyone tried to use their TyTN with a WRT54G Router. I can get it connected to the wireless signal and it has a DHCP IP but I cant seem to get it to automatically pickup the DNS servers. I an connected to the WAN via PPPoE. The connection is 100Mbit FTTH. The PCs wired to the network can get on the net just not the TyTN on the wireless signal.
Any help is appreciated.
Nevermind
Put the DD-WRT custom firmware on there then set the DNS servers manually and its blazing.
Hermes (Dopod 838 Pro) and the WRT54G Router Issue
I have the same problesm! I run a WRT54G router AP at home and created a MAC list that enables access. Of course I updated the MAC list filter on AP. I get to connect my JasJar, but no such luck with the TyTN. Then I hooked an ASUS portable access point to one of the routers cable slots and my TyTn connect seemlessly!
I read the DNS suggestion and alos trying to run the AP woth fixed IP! I would then have to do that for all systems that access the Routre, right! Isn`t there a way to make th 54G work with DHCP and assign IP addressess dinamicly to the TyTN, as it does to any other WiFi equiped device?
Try this;
Check what type of wireless encryption you are using. If you are using AES then create another SSID or change the current SSID to use TKIP for your TyTN to connect to. I don;'t think the TyTN supports AES.

oops, ignore my reply. Clicked on the wrong button and accidently replied here
you can always do this... sell your linksucks on ebay or to a friend then go buy a better router i have seen many issues with linksucks and HTC devices, there was tons of weird issues with the wrt54g and the wizard
Mine works without issue. I do have the sveasoft firmware loaded though. I also don't use pppoe.
Load the DD-WRT and it's very stable..
I have a DLINK 604T and it work with no issues with dynamic IP/DNS. This router is also cheap as compared to lynksys
WRT54G working FINE with Hermes 100
Hi Everyone!
If you own a WRT54G router/access point and were experiencing trouble to connect your Hermes 100 to it, sweat no more! Go www.linksys.com, select downloads and choose from the long list of routers. Make sure you match the model number and the version number of your router. Download the FIRMWARE upgrade. I was running the original firmware from my router a WRT54G V1.1. After upgrading the firmware, my router worked great and the range was almost 4 times what I had before!
Check it out!
Cheers

Was a bit worried as read this before my Vario II arrived and I have a WRT54G...
Connected fine 1st time... just added MAC to filter and put key into vario. bingo-bango!!
FYI I have WRT54G Firmware Version: v1.42.2 (the firmware I bought it with)

WLan and WPA

Searched and searched, Has anyone had an issue with using the wlan SD8686 with WPA?
I can connect with no security and with WEP and I am able to browse the web.
I can still connect to the router using any of the WPA but can not get any pages to load in IE only works with wep or no security. 3 other laptops work fine.
Any idea? HTC Tech support no help.

I can't answer.. but that reminds me the WPA issue that I have with the HTC Touch ..... my Touch is unable to use any WPA ... when connected the touch just freeze .. and I have to soft-reset and hope to the Wireless not connecting before being connected before disabling the Wireless.
it seems that WPA or the wireless chip is really bad ... but don't know which one !
Shift works fine with WPA I am currently using TKIP+AES
I have had nothing but issues with my Shift and Belking N Router using WEP...
Sometimes it would connect, the majority of the time the shift couldn't see the network and it did connect it would lose connection. I tried it with WEP and also with no security and also with MAC address authentication only. Every 50 times I tried to connect, it would connect maybe once.
So, decided to use my old standard 54g Belking router. Guess what, no issue so far with no security applied. Was planning to try it with WEP later....

I live in US and unit was from UK think this could be a problem with WPA?
I have no problem with NO security and NO problem with WEP only with any type of WPA. Also searching the net, seems like the wirerless chip in the SHIFT not a very good track record, lots of driver issues

I had problems, sometimes the shift could not find my network, sometimes it woeked.
after setting my dlink dir655 router in b/g moder rather than b/g/draft n mode all has worked so far.
ok guys i use linksys running open source dd-wrt v23 sp2 firmware; works great; i must admit i have not used the shift on other wifi network routers....
No connection
Hi,
maybe someone can help. Since yesterday I belong tot he proud owners. But, but, I can’t get a connection to the internet over my WLAN router.
Router Netgear WPNT834. Whatever I did no luck: either I get the message: limited connectivity or only local Zugriff connection something like that.
No problem with XP notebooks, but with Shift and Vista.
Has anyone an idea what causes the problem? Is it the router?
Do you know any router you can recommend: strong signal and reliability?
Thanks
Settembrini
No issue with WPA here
Hi Settembrini,
So you got your Shift from Amazon.de at the same time as they delivered mine after all
Regarding the WiFi connection to the router, it seems to be some routers / chipsets.
I am also using WPA (with a Siemens SX550i router) and it worked without any problems. The Shift detected an encrypted network with hidden SSID and after I entered the SSID and the encryption password it connected immediately and with a stable connection.
WLAN access
Hi mw65719
yes, more or less same time.
So what is the conclusion? It is my Netgear router WPNT834, why I do not get a connection? Need for a new router it seems!
Thanks!
S.
Yes same here, I just bought the new Belkin N1 Vision router and all other equipment works but the Shift can't even see the the router. I just hooked a netgear router in series with the belkin and the Shift can now see the Netgear..... Was worried for a bit there.... Really annoyed about the shift not being able to see the belkin, the Belkin wasn't cheap.
Hi,
I was not able to establish a connection to my Netgear router WPNT834, then I tried the Speedport 700 V and it worked without any problems, no special settings in Vista neccessary.
I guess you have a different Netgear router than mine.

This WiFi issue is killing me!

I know Google has said they are looking into it. But this is ridiculous. The N1 can not handle WPA2 connections. Even though it saves the connection and password, it almost never reconnects automatically. From what I was reading on the Google help forum, it appears to have compatibility issues with many retail routers and they suggest upgrading the firmware on our routers. Throughout my day, I may connect to 3 different APs. One is a standard Linksys wrt54g with sveasoft, the others I connect to are Cisco APs.
None of them automatically reconnect. Most of the time on the Linksys, I have to delete the connection on the phone and re-add it.
I still like this phone but between the 3g and wifi issue, it is a pain to use.
I won't pretend to understand all that you just said, but I can tell you that my router is set up using WPA2-PSK. Not sure if it is the same as just WPA2 but my N1 reconnects to mine whenever I get in range. Then at the office it will connect to the WPA2-PSK set up in there, and one more regular open connection that is available at our pool. Pretty much every time I look at it, it is connected to one of those 3. Or else if I am OOR of any of those, I am on 3G.
My home router is a Belkin -N. Work routers are a Netgear -N and a D-Link -N.
I've got a Netgear WNR2000 on WPA2, and I can confirm I occasionally have this issue with the phone not connecting to the network automatically. It usually does if I go into settings and touch it to reconnect again.
There is an easy solution for any WIFI problems, use a Mac Filter!!
I have to go into Settings > Wireless & Networks > WiFi Settings before my Nexus One will reconnect to my home router, which is also using WPA2-PSK.
Hopefully it'll be sorted in a firmware update, it is annoying having to go through 3 screens to do something that my Nokia Symbian phones have been doing without issue for almost5 years...
I am having no problems auto connecting to my home WPA2 network, I am using AES encryption and running DD-WRT firmware if it helps.

Mac Filters are no replacement for WPA2 or encryption. Almost every device has the ability to spoof a mac address. Using a mac filter might help quickly eject roaming devices nearby, but it is NOT security.
Its like using a No Trespassing sign to replace locking your doors and windows.
i found that APNDriod may be a possible culprit....
Before I installed APNDriod , every times I go back home, my N1 will connect to my home WiFi almost immediately.
But after I install APNDriod, my N1 will not connect to my home WiFI.....I need to go into the Wireless setting screen, once i am on that screen WiFi it will connect.
But it is strange this I don't have this issue in my office, it just connect automatically before and after installing APNDriod.
Today I tried NOT to use APNDriod for a day and my N1 connect to my home WiFi without issue..... will do more experiment tmr.
Netgear WNR3500 w/ WPA2-PSK. Reconnects every time I am in range.
I find that my Linksys is the worst. The Cisco Aironet 1121 is better, but still has occasional connection issues. And I have not installed APNDroid.
On another note, when my phone switches from 3g to 2g and vice versa, it takes a long time for the data connection to resume
My network at home is setup with WPA2. I have no problems connecting to it... I click on the little wireless icon, and wait for it to say "wireless settings updated" and also wait for the wireless icon to show up near the time... then i will start browsing
I have a Dynalink RTA1025W
My wifi is working now. See h**p://forum.xda-developers.com/showpost.php?p=5773148&postcount=26
No problem reconnecting to my home network with WPA2 . Apple's Airport Extreme.
No problems here connecting to my Belkin N1 router. Connects the moment its in range.
Setup using WPA2-PSK
im having this exact same problem on my D-link Dir 615!
Pisses me off alot, i hope Google fix it!
I found that unless I was on channel 6 or 11 I had issues
AES-CCMP, TKIP or WPA Cisco521G will not connect
My cisco 521AP does not connect using any type of encryption, it only works with open authentication. Expensive phone like this that doesnt work with business class products is a joke.

My suggestion is - check what you're doing wrong before assuming the phone is at fault. And check that you're using PSK.
SEC AUTH ENCRYPTION
No security None Open - working
WEP WEP Open - no
WPA-PSK TKIP WPA-PSK - no
WPA2-PSK AES CCMP WPA-PSK - no
