Making the Wizard act as a bluetooth Wifi Modem?

I know that it's possible to use the Wizard as a bluetooth modem, using your gprs as the active signal.
Since the Wizard supports WiFi aswell, isn't it possible to use the Wizard to connect to a WiFi network and then sharing that connection over bluetooth.
The reason behind this is that I recently moved and we're sharing a wifi connection in this house. But my signal is very weak in my room, but the kitchen next to my room has a signal strenght of over 70%.
I know that buying a better router of signal enhancer would do the trick, but we're poor students

Theory says yes, but I have asked this same question without much luck or a definitive answer.
I have been trying to do the same with a laptop, bluetooth and my lan connection.
Apparently, you need to configure the outgoing bluetooth device, in this case the PDA, to act as a proxy server.
When I linked my laptop to my desktop over bluetooth, it creates a PAN (Personal Area Network). Its IP was set at 169.254.x.x
A LAN networks at IP's of 192.168.x.x and XP wouldn't let be bridge the two together. (Because of the IP differences.)
It would be the same scenario for the PDA.
I am relaying what I have basically learnt but have no idea of which way to take it now so if you have any luck, please let me know.

hotel room without wireless

Anyone know how to convert CAT5 Cable to wireless in the Hotel room. I love to bring my PDA with me , when I travel. But, I found a problem to using the internet in most of the hotel.
Problem: Most hotels only have CAT5 network , when you plugin your notebook computer, you have to go to the login page to login. But when you using PDA(wireless). The question is how to use the internet?. If you bring a wireless rounter with you. When you plugin . how to make it found the hotel login page on your PDA?

Easiest method is to buy a Wireless bridge. Linksys sells these. Its a device that will tern an Ethernet Cable into a wireless signal.

I travel a great deal and although there are a great number of ways to deal with this issue...this is how I get around it.
I bought one of the little Dlink pocket routers like this one for a great price (less than $30). What you can do with this product (and others I'm sure...) is clone the MAC address of your laptop's ethernet port. Basically...it'd work like this...
1.) Plug your laptop into the hotel network.
2.) Jump through their proxy hoops to get out onto the net.
3.) Unplug the cable from the hotel network and into the pocket router.
4.) From the router's config pages...set the NIC to clone your laptop's MAC address.
5.) Plug the hotel network into the pocket router WAN port.
Badda bing! You're sharing their network wirelessly...doesn't take a lot of time at all. I've really enjoyed the Dlink one I got...small...flexible...and it comes with a nice travel case. Linksys (or Cisco now), Apple, and others all make similar products and some of them have the benefit of not needing a power adapter and just plugging straight into the wall outlet (a big benefit IMHO), but I can't speak for exactly what kind of functionality they provide versus the Dlink product as I've never used them.
By the way...a bridge will not help you do what you want...you need at least an AP...but if you get one of the devices like I mentioned...you get the added benefit of a NAT firewall between your device and the hotel LAN (which can be a very good thing by the way).

I can't see why you can't just plug in a standard access point via the WANport. Set the internet connection to Automatic DHCP.
Then the first time you access the net it will be ready for logging in.

Because many hotels control access to their internet connections by utilizing various methods but most often by controlling access via MAC addresses. Think filtering a wireless connection by only allowing certain MAC addresses... Now...if an AP allowed MAC address spoofing...then I certainly don't see why just an AP wouldn't work just as well (other than the fact that you don't get the benefits of a router).
By the way...this topic is certainly not Hermes specific and should likely be moved to a more appropriate forum.

One note should be made.... If the hotel is using NAT to assign IP addresss, and you use a second NAT with your router... you may not be able to use various VPN clients. Double NAT'ing doesn't work for many IPSEC VPN clients. i.e. AT&T NetClient
A number of switch vendors offer the ability to limit each port on their switch to allow traffic to one MAC address per port. A bridge would show multiple MAC addresses and typically when the switch sees that, the port is automatically shut down. This is done in many cases where there is a $10-15 a day charge for internet access and the hotel doesn't want you setting up an AP to share the cost with your travel mates. Thus they limit to one MAC address per port. The router solution would show up with only one MAC address... but you then have the double NAT issue in some cases. If you are not using a VPN, that may not be a problem.
Just some additional data points to consider.

I love the linksys travel router - more expensive then their mini router (about the same size) except for 2 things that are key for me. First, it's powersupply is embedded and 110-220v and 2 - it let's you connect it to a hotel wireless hotspot and then share that hotspot over wifi. This is great - it means that 4 people with rooms next to each other can share the fee of the hotspot and share it. It also means I can share that same hotspot with my phone! The only downside on this one over the mini router is it only has one wired out jack but that's no big deal for me!

Note that plugging a router into a network jack when the site in question is set up to use DHCP can cause some havoc on the network. I doubt many hotels are savvy enough to start hunting around for rogue routers when people in the hotel can no longer get IP addresses, but bear in mind that it's always a possibility. It's probably not a good idea to leave something like this plugged into the network longer than necessary.
Also note that whenever I've encountered a location where the establishment requires you to log into a web page in order to access anything, I've had no problem doing that from the Hermes.

The one I mentioned only asigns an IP to people on it's end and not outside - it even uses it's own IP range. It is designed to be transparent to the existing network.

Yes, I know. However, depending upon the network setup, this can still cause problems.
For example, some versions of Symantec's 'On Command/CCM' (a suite for pushing software updates to computers automatically when they are booted on the network) can communicate with some routers in such a way to where the router thinks it needs to try to provide one of its IP addresses to the network. This invariably ends up having a computer in some random place on the network ending up with a 192.168.x.x IP. When an admin sees this, he/she knows that there is a rogue router on the network.

Alot of work... as you know these hotel internet connections are controlled. If you're posting here use that 3g or even edge instead of giving the hotel your credit card to have a field test (is that a ppc program?) or field day with.

Well I doubt this will happen in most hotel networks and aside from that - I doubt that there is hardly ever a network admin on hand 99.9% of the time

The Linksys Travel Router is the product I'd highly recommend as I've been using it around the world for some years now.
It has a hardware switch that let's you control its functionality. In one position, the Wired Ethernet is simply converted to Wi-Fi and once you connect, you still get the IP from the hotel's DHCP server. If you need to share the connection with more systems (such as your laptop and your phone or with some colleagues in adjacent rooms), you just switch to another mode after logging in to the hotel's network and the Linksys becomes a NAT router and gives you a private IP.
It also comes with a nice travel case...

That's the device I've been talking about - the only thing I add to the kit is a european outlet adapter (which fits nicely inside the coiled ethernet cable included

[Q] Wifi issue. New findings?

Hello, been a long time reader from my G1 to my G2 and now my nexus 4.
I am unfortunately not able to use my device on certain wifi networks which is a real bummer.
Being that i have a background in diagnosing computer problems in my real world life, i thought i would post my findings as i found some interesting things!
First i will say that the network i will use as the demonstration is secured with WPA2 PSK AES security and encryption.
I can connect to it and often find i have problems on the first connect to the network. By this i mean if i have made my wifi settings 'forget the network' and then try to connect again.
On the first time it seems to indefinitely hang, showing the message 'authenticating' on screen next to the network and if i long press on the network name and press modify, the dialog shows that i have a link speed of 1mbps.
I can usually get past this by turning wifi off and on and then reconnecting, at which point it will connect straight away and have a normal link speed. (in this example 72mbps).
After i am connected, i find that the following does not load:
-browsing webpages through chrome does not load
-the wifi icon turns grey
-play store cannot load anything
I find that i get assigned an ip address by dhcp correctly too with the right gateway and dns.
I decided to download a network tool to have a better look. I use fing personally.
I found it very interesting what i found, which no other threads about wifi issues mention.
Network discovery found every device on the local wifi network.
I was able to scan the services of my computer which is also on the network and it found everything, including a http server which i run which i could browse to.
In fact i could do everything through wifi with this device and most others.
Again it got interesting when I then took a look at my gateway, the router.
I had discovered its mac address which i can verify through my computer is correct which to my understanding, being that i can communicate through the wifi, means that i have the information available to send information to that physical device?
When trying to scan services, i find nothing, which is not true, at the very least it exposes a http server on port 80 which my computer can access.
When trying to ping i have 100% packet loss.
So at this point it is only the gateway i cannot access.
So i figure i could setup another computer which is connected to the network with a wire to share its connection through wifi onto that network and then i have a standin gateway?
I connected this computer through wifi to the network and pinged it succesfully with my phone. I then turn ICS on my wired adaptor to share to my wifi adaptor. I ensure that the wifi maintains an ip address in the right range and subnet.
I then try to ping that ip with the phone and it then gets 100% packet loss.
Could this be that when a device is configured to act as a gateway something changes about how it handles any packets sent to it that the nexus 4 is currently in compatible with?

I have found a bit of a workaround that i can use!
When i said i turned on the wifi and ICS i did the following:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the wireless to 192.168.10.x and gateway to my router 192.168.10.10
-I then tested.
I ran through this again but slightly different:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the phone to 192.168.137.5 with gateway and dns as 192.168.137.1
-I then tested. And it works!
I know this doesnt fix the wifi issue itself, but for me, this makes a big difference as i can now use wifi at work where we also have poor mobile network coverage.
Edit:
Additionally i previously tried to setup this same computer to host a wifi network to share the connection using 'netsh' and creating a 'hostednetwork' but i found i was in the same situation where i still couldnt get the internet.

[Q] Tethering Issue

I am hoping someone would be kind enough to help, I have spent hours searching the net and still can't find the answer
I have the Note 3 on Three UK which allows unlimited data and tethering, I can tether to my PC no problem.
I want to tether to my wired devices which I currently connect using a router and Netgear WN3000RP Range Extender, this set up works fine when I connect to my main router.
I tried to set up my tethering to the WN3000RP and it connects, but does not share the connection. I did the firmware check and it said there is no new version - so that tells me the extender is accessing the internet, but going out of it, no connection to the internet
I have tried pinging 192.168.43.1 which is no use - fail
Has anyone done this before? is there an app to help?
I am not sure what the problem is but I have tried everything - resets, reboots, restores etc.
Thanks in advance

what are your wired devices looking for as the default gateway and DNS, are they trying to DHCP for their address?
If they can identify the phone and ping it then at least you have comms up to the edge but the gateway and DNS need to be set for them to reach further and out to the web.

After much hair extraction, I think I have finally figured this out!
I was not setting any security and using MAC filtering on the phone instead of encryption as the bridge was struggling. As soon as I connected the extender, I added it as an authorised device, then connected to my pc and nothing.
After much messing about, I put some rubbish apps on which reset all the settings and renamed the APN to (APPNAME_COOL) or whatever it was and removed the MAC Filtering - and it works
So, I dont quite understand this, but the setup goes
1) Note 3 - WIFI Tether
2) Netgear Range Extender - RJ45 to
3) Netgear DSL Router - RJ45 to 4 different devices
Now all these 5 devices show up as connected by wireless, I thought the router would be connected to the extender and the extender to the phone as totally different devices, not passed down each step of the way.
Oh well, now on to the next amazing challenge, I have just put OpenWRT on the router and am aiming to set this up with my ADSL from downstairs and my DC-HSDPA as a "Bonded" connection to give me download speeds of about 40-45meg!
Thats a long way off though as I have not even got 1 connected via wireless yet, so still using extender+router
Not too shabby, but could be better

good to hear you got it working
I take it your DSL router is connected to an ISP? You may find that you get contention between the router and the tether in terms of where traffic ends up going, will depend on where the devices see the default gateway taking them. If the router were a cable type you might get away with the extender plugged in to the WAN port so all traffic would route via the 4G tether. Wouldn't then extend the range for other devices that well if the phone isn't there to provide the uplink to the isp.
Am on EE myself, not unlimited data (3GB) but last check I got 40-50Mb download and 24Mb up

WIFI & Mobile Data Simultaneously?

Hi, New poster so if I've posted in the wrong area please don't bite
I've been connecting my phone to a smart device (miracast-ing 'direct') but as of late the connection has become unstable and generally unusable. I had the brainstorm of using an old router to stabilize the connection, this seems to have done the trick but now I'm unable to access the mobile data as WIFI has assumed priority. Please bear in mind I don't have home internet so the router is being used solely as a go between for phone and smart device. Is there any possibility of WiFi connection whilst have access to mobile data or is this just a pipedream?
Thanks in advance

You can just start a wifi network from your phone, connect the smart devices to your phones wifi and use mobile data normal as internet connection (this is standard if you start a wifi network from phone). You wouldnt even need the router with this szenario, if the wifi signal of your phone isnt strong enough you can connect your router to the phone and extend the wifi with the router.

But creating a mobile hotspot won't help because it doesn't solve the faulty (actually non-existent) miracast connection, plus I don't need a hotspot because only the phone needs internet access. My earlier explanation was probably a bit vague.
My goal is to mirror my phone's screen but to also have internet access solely on my phone.
Phone➡Smart Device➡Display - Can't connect (used to work faultless).
Phone➡Router➡Smart Device➡Display - Connects but no mobile data available because the phone thinks the router has internet access covered.

Creating a hotspot is not for giving the other devices in your network internet access, this is the only way you can use the wifi on your phone with using mobile data at the same time. I dont know why but android devices never use mobile data when they are connected to a wifi network and there is no internet access available. So if you configure your router as a wifi repeater and setup the phone as base station, your wifi signal from phone to router should be good and you can connect your other devices to the router, the phone should see all devices in the same network if you stop the dhcp server in your router and only use the one from your phones hotspot. Should look like this :
Phone (with DHCP) <----Router---->Smart Device---> Display

Cheers will try it out.
Hopefully that sort of config is available on my router as it is loaded with a custom firmware from my old ISP provider.

Router ISP custom firmware seems restrictive (no advanced wireless settings) plus WDS is not officially supported.
Possibly achievable but beyond my technical savvy
Thanks for the advice anyways.
