Protocols / Routing :: Thinkpad W500 Bluetooth Poor Audio Quality
Jul 17, 2012
I recently bought a Bose Soundlink bluetooth speaker and have paired it with both my ipod touch and ThinkPad w500. The iPod Touch sounds great, but the audio coming through the speaker via the w500 sounds like it is clipping, especially at normal-loud listening levels. Both the soundlink and the w500 have the latest bluetooth driver updates installed. The clipping occurs even when the main volume (and iTunes/Spotify) is turned down to 50% power.whether there is a way to reduce the "power" of the bluetooth signal so it does not cause the speaker to distort. Audio played through the speaker via 3.5mm from the w500 sounds great even at high volume.
Currently installed bluetooth drivers:
Bluetooth Enumerator (Microsoft)
ThinkPad Bluetooth 2.1 with Enhanced Data Rate (Broadcom)
Bluetooth Hands-free Audio (Broadcom)
Bluetooth Remote Control (Broadcom)

I have a wireless router on the ground floor of my home which is wired to my PC on the 3rd floor. The wifi signal is of poor quality on the 3rd floor. I cannot move the router to a different floor since all of my connections are wired through the home into my networking room (on the ground floor where my router is). I wish to add a media receiver to a different room on the 3rd floor that is not wired already for networking. Streaming video files wirelessly to the media receiver from my router will not work because as stated previously the signal quality is poor on the 3rd floor. My mobo on my computer has ASUS wifi GO. Can I enable the wifi go on the mobo of my PC (located on 3rd floor) to connect to the media receiver (also on the 3rd floor) for streaming? The media receiver will also have an internet browser so will I be able to connect to the internet as well if it is networked to my PC and my PC is connected to my router on the ground floor?
I basically want to keep my PC connected to my main router for high DL speeds and also have my PC networked wirelessly to my media receiver using the on board wifi go. If possible I'd also like to be able to access the internet on the media receiver via the PC.

I have a client using a VOIP service to a third party provider (RingCentral). They are connected via Cable ISP (6mb) to the Internet and now experiencing performance issues with their VOIP service. They indicated that the call can be heard but that there is jitter and choppines in the call and they have to place a regular landline call. Their provider recommended using QOS to improve. I did not see anything straight forward on the ASDM interface to do this and figure it may require command line to accomplish.
They have Cisco IP 303 and 5252G2 phones which connect through an ASA5505 7.2(4) to their provider for service. Apparently the voip app uses the following ports:
UDP
5060-5090
8000-8200
16384-16482
What would be the best solution to improve performance or perhaps traffic shape / priortize traffic to work. I assume this may be happening if there are heavy downloads or activity happening on the network. The ASA5505 is on 7.2(4). Some coded examples for the above info.

I bought my first Dell laptop (Inspiron 7720) and I can't make my bluetooth audiosystem (Logitech Mini Boombox) to work. I've got positive experience on Fujitsu-Siemens Amilo Xi2550 and on HP Compaq 6530b, where I had to just download another drivers for widdcomm bt adapter. I tried to do this trick o this computer, but I get only three bluetooth peripheral devices, which I can't install, because there is no driver for them. What shoud I do to make audio transfer through A2DP to work?Bluetooth drivers are working, I am able to pair the device. Problem is in instalation of all services.

I have below setup.
1. Comcast cabel modem with highest speed of 8Gb.
2. Linksys E1000 router
3. three devices-- Lenevo W500 laptop(2 years old), Nook(latest) and Lenevo G550 (6months old)
4. Earlier I had WRT54G router and all were working fine.
Now, I replaced WRT54G with E1000 router and symptoms are below.
a) on my W500 laptop, it works fine with Wired connection but when I switch to wireless, the internet speed reduces drastically in 10 minutes and finally crawls..
b) other devices (nook and Lenevo G550 are working fine withwireless)
Called Linksys support and they blamed on laptop and comcast cable.

Had problems with voice quality on VoIP with 4500 series switches and the qos dbl feature (which gets enabled by the auto qos feature)?? I have had a couple of customer complaining about voice quality and our voice team spent a lot of time investigating; I had ruled out the network infrastructure because it was all QOS enabled. The voip people came up against a blank so I looked at the network once more and disbaled dbl with hope more than anything else. Mysteriously the voice quality issues the customer was having have now disappeared. Not sure whether a coincidence (though I have done this on two customers now) or something to with with dbl. There is nothing on this on cco.

We have branches all over the country and we take different links like fiber (Ethernet) radio links etc. Now sometimes when we ping from branch WAN ip to its gateway or to the aggregation router (ASR 1000) in this case, we see some drops, but see no problem in actual HTTP or lotus communication.
What i want to know, that now a days, should we rely on ping results to determine link quality ? or should i use tools like iperf to basically see if the link is actually treating tcp and udp packets properly, I have heard this countless times that normally network devices like Cisco routers, even without any QOS, will give low priority to ping packets.

I have 5x Cisco 2960 and 1x Cisco 2960G. All of them are using IOS Version c2960-lanbasek9-mz.122-55.SE6.bin I'm having poor inbound speed with ALL of the Cisco 2960 (except 2960G) although the outbound speed is normal. The port is 100Mbps Full-Duplex, but the max inbound speed on a single connection is around 35Mbps. With the 2960G, I can get max 1Gbps inbound speed on a single connection.
I checked everything and still not know why the 2960 switches can't get max 100Mbps inbound.

We have a NETAPP nas box having two interfaces connecting to two fex's on 5ks. The 5ks are inturn connected to nexus 7k boxes. We have a 100mbps man link (LAN Extension). The netapp's two nics are grouped together to form a teaming type of environment. SNAPMirror replication is very poor at the rate 10mbps though the WAN speed is 100mbps and also the wan link is utilized only about 60mbps. What could be the problem. We tried removing storm unicast control 10 but with no effect.

What's wrong with my config? If I shutdown a port or pull a link it takes ~30 seconds to converge.
I have set spanning-tree portfast default on the 4948's. Is it proper to set my uplinks on these switches (g1/1) to shared or does that disable RSTP?
Switch 1 & 2 are 4948's running 12.2(54)
Switch 1 & 2 are connected on port 43
Switch 1 port 1 is connected to the 7609 12.2(33) SRD5 on port g1/2 Switch 2 port 1 is connected to the 7609 on port g2/2
I have a host on Switch 1 port 42 for testing.

I have a thinkpad, and my friend next door said I could use their wireless which is set up through COX. I click on the icon at the lower right that shows wireless strength and a window opens up called "access connections" I don't know what to do from there. I see the wireless icon for the one next door on the diagram, I click on it which highlights it, then I click on "connect". It looks like it is going to connect because a green bar starts to fill in the "location" : "name" place, but then a little window pops up that says "connection failed.Recommended action: Verify that the encryption settings (WEP/TKIP/AES) specified in this profile match those expected by the wireless network.

I have a Linksys Wireless router WRT54G, I am trying to connect a IBM Thinkpad T42 with Windows XP. I have the right Router name and password, but all I keep getting is "Acquiring Network Address", but not connection. Running "WPA" on security. The laptop works fine when connected directly to the router via cable.

I have an IBM Thinkpad T42 Model 2373.This morning I had to factory reset it, and lost all of my drivers. Slowly, I'm getting them back, but I've lost my wireless internet ability. I've attempted to turn my wireless on, it says IBM Wireless Adaptors (802.11 or bluetooth) are not installed on this system. My card is an Intel(R) Pro/1000 MT Mobile Connections, and I understand that this isn't a wireless card. But. I've had wireless working for the past year and a half...

I bought an old IBM Think Pad laptop and i cant seem to connect to my wireless router. I have another laptop which connected with no problem just simply typed the wireless password in and all work fine and the same for my iphone. First problem was when I got asked for the wireless password it came up with a message say " The network password needs to be 40bits or 104bits depending on your network comfiguration".

After working fine for months, the network on my ThinkPad R61i has become slow and intermittent. Often after a reboot, it will work fine... then after several hours it will get slower and slower to load pages, sometimes failing to load them entirely. Usually, after several minutes of inactivity, I can refresh a bunch of stalled pages and they'll all load fine, and it will work again okay for a few minutes, then slow down again. Often a reboot will clear it up, but not always. .

I've spent several hours trying to see if it's even worth trying to upgrade my old Thinkpad i1400, which has Windows 98 and only a modem internet connection. Obviously in today's world it's wireless or nothing. So...I've read that I could upgrade to Windows 98SE, and on [url]... the used disk is only about $15. I also read that 98SE has a lot of glitches. However, I already have an XP disk (don't know how I got it) but it may be corrupted, because it never finishes the installation on the thinkpad---goes completely blank after about 10 minutes. One problem is the limited hard disk space on the i1400 --- about 2.5 GB for both the C and D drives respectively. There is less than 1 GB on the C drive free and XP takes up almost 800 MB. I'm afraid to wipe clean Win98 and replace it with XP, and for some reason I can't install XP to the D drive. Even if I could accomplish this, will XP be the magic bullet that gets me wireless on this dinosaur of a laptop?

I am unable to locate my wireless adapter on IBM Thinkpad R50 after I had to re-install Windows XP. It was not the cd that goes to the laptop, as I did not have one because I bought the laptop used. I went to the Lenovo website and have installed just about every driver on support page and still NOTHING.

I've come across an older IBM ThinkPad 2687 via work that was just collecting dust, and it was able to connect to a wireless network.Due to other issues with the machine, I had to do a complete refresh on it, so it only had the XP OS.
I had to update the drivers to make sure other things like connecting to a flash drive, and connecting to a local area was possible, which is how I'm able to connect now.However, I've been unable to access the wireless connection within Network connections. I've downloaded the different drivers from the Lenovo IBM ThinkPad website, but still no luck.

I 'm very happy with the AE1000 & got it to work with my A31p by using a USB 2.0 adapter; (it only has USB 1.0) I think the ThinkPad PCMCIA card is faulty because it only works for a brief time & then dies (works fine with current machines)--then I noticed that the newest driver supports USB 1.0 but exactly how is that file implemented? I don't see .exe files, etc, & want to try to use the new driver--I'm using the latest XP--is there a step-by-step tutorial describing how to use the new driver?

I have got a PC at work (Windows XP Pro SP3) that is on two networks with the IPs 10.20.30.167, subnet 255.255.255.0 (internet enabled) and 10.0.0.20, subnet 255.255.255.0 (no internet). On the 10.0.0.X network there is a gateway with the IP 10.0.0.200 allowing access to another network; 192.168.60.X, subnet 255.255.255.0 (no internet). I have added the route on my work PC to access the 192.168.60.X network via this gateway and I can access all PCs on all three networks from this PC.Now, I am using LogMeIn Hamachi so that I can access the networks at work from home. The PC at work is the 'gateway' PC on the Hamachi network. When installing Hamachi it created a new network connection and bridged this connection with my 10.20.30.167 network adapter to allow access to the 10.20.30.X network from an external PC when connected using the Hamachi VPN connection. I have manually configured my Hamachi connection on my PC at home to the IP 10.20.30.169, subnet 255.255.255.0, with the default gateway set to 10.20.30.167. I can ping all computers on the 10.20.30.X network from my PC at home.
I then added a route on my PC at home for 10.0.0.X to go via 10.20.30.167 (the 'gateway' on the Hamachi network). I also enabled IP forwarding on the 'gateway' PC (my PC at work). I can not ping any PC on the 10.0.0.X network from my PC at home apart from 10.0.0.20 (the other NIC in the Hamachi gateway PC) and 10.0.0.30 (another PC on the 10.20.30.X network that is also on the 10.0.0.X network).Now, with IP forwarding enabled on the Hamachi gateway PC I would assume after adding the route on my PC at home for 10.0.0.X traffic to go via 10.20.30.167 that I would be able to ping all PCs on the 10.0.0.X network...I also tried adding a route on my home PC to send all traffic for the 192.168.60.X network via 10.20.30.167 which has a route via 10.0.0.200 to the 192.168.60.X network, but this also did not work.I then tried adding the 10.0.0.20 network adapter into the network bridge that the Hamachi connection made, also keeping both IPs (10.20.30.167 and 10.0.0.20) on this network bridge by adding them into the 'IP Settings' in the 'Advanced TCI/IP Settings'. I also added the 10.0.0.200 gateway for good measure. I still cannot ping any PC on the 10.0.0.X or 192.168.60.X networks from my PC at home.
I have also added the route to the 10.20.30.X network on a PC on the 10.0.0.X network to go via 10.0.0.20 and tried pinging a PC on the 10.20.30.X network but this also has not worked. Also setting the default gateway on a PC on the 10.0.0.X network to 10.0.0.20 does not allow this...Surely bridging the networks 10.20.30.167 and 10.0.0.20 on my work PC would allow another PC on the 10.0.0.X network to access the 10.20.30.X network after adding the route or setting 10.0.0.20 as the default gateway?

We are having issues transferring a 200GB VHD file across our point to point without being corrupted in the process. Any good application for testing the line quality across the point to point?Preferably we want something free, but if there is an in depth tool that costs money, we are open to that option as well.

I took my router with me to visit family at Christmas. It wouldn't allow the wired computer through the switch, but yet I could talk to the router with my laptop. Rather than reconfigure, I bundled up my router & laptop and let well enough alone.Now that they're all back at my house, I can't reliably get the laptop to connect - Low Wireless Signal error. I've reset the modem & router repeatedly. Tried Channels 1,6, 11 and 8&9 too. n only, as that's my laptop's. On 2 occasions it has connected, rebooted and auto connected and run for 4-5 hours. Then it's gone. I've beat this mess for 3-8 hours per day, for days...!!!Laptop(Vista) connects to every other wifi I've tried. It's sitting 4 ft from the router.
misc. info.
separate dsl modem, Centurytel, Netopia Cayman 3300 series
no other devices beyond wired desktop and laptop
no changes in other neighboring networks
