Speed up BlackBerry Wi-Fi connections a knottyrope tip

[ Edited ]

These knottyrope tips might help you out. This is not an end all solution but I have come across these issues in the past years. Go slow and document what you do. Worst case is resetting your router to default and starting over.

 

Router running latest firmware? Update it as many are shipped with and old version as they sometimes sit on a shelf for months.  Also a Wi-Fi router more than 5 years old might not work well with multiple devices.

 

Using a Hidden SSID? You should never hide SSID - hiding SSID is a violation of the 802.11 spec and this can be a pain with setup. Most new devices can see them anyways.

 

Using the same SSID as your neighbor? This is not good, you need a unique name or it can try to connect to both. I have seen NetGear 5 times in one neighborhood and after a simple name change you can have fast Wi-Fi

 

Using 2.4 and 5 ghz on one single SSID? This can be a burden, drop it to 2.4 and it could make a difference. Newer routers support a separate SSID for both frequencies.

 

Using WiFi B? If not using B then disable it or a rouge device might try to connect and knock your speed down to B speed.

 

WEP vs WPA? Not all N devices support WEP or WPA, Best to use WPA2 if all devices support it. Don’t try both WPA and WPA2 as some devices get confused. Some Wi-Fi routers do not support WPA2 AES-CCMP just AES, see if yours supports it. Most newer routers do have accelerated AES encryption but not for WEP. Older encryption methods will be slower.

 

WEP can be hacked in minutes not matter what password you use. If you have no choice but to use WEP, use only one WEP key as some devices will not know what to do with the other ones. Remember thath this encryption method will be slower.

 

Channel speed settings 20, 40 or both? Try 20 as most will work on it. Some devices will not like 40 only or even set to both. Check this on both 2.4 ghz and 5ghz on dual SSID routers. Using the default channel your router was setup with? Try a different channel other than the common 6 or 11 channel. Use the Auto Channel hopping feature if your router has it, mine didn’t work but it may for you.

Using Multiple Wi-Fi routers? place them on separate Wi-Fi channels so they don’t interfere.

 

Newer routers do QOS better so don’t be making this change right away on a newer model. older models with QOS for WMM Wi-Fi multimedia and VOIP priority on older models may not work well. if you don’t need or use it, don’t enable it. I turn off all QOS settings with great results since we don’t use the features.

 

Does your router only support 1 VPN connection? If this is the case then you might not be able to access BIS over Wi-Fi when other devices are using it or VPN. Many newer routers support 4 or more VPN connections.

 

DNS servers slow? Try OpenDNS.org and see if speed improves.

 

MTU matched up? Not a common issue but this can be a fun one as not all routers will set it to your ISP setting. 1500 is a standard but you can try 1492 for DSL lines or ones that use PPOE.

 

Using Extended range? If you don’t have matching card for your brand router it might not work well. Try turning it off.

 

UPNP turned off? Turn it on as your device may setup some port forwarding rules.

 

Using ISP modem and your own router/Wi-Fi router? Don’t enable NAT on your own routers as Double NAT can cause connection problems.

 

All port speeds matched? Check your Router WAN port speed, mine was set to 10Mbit by the ISP before. Also make sure its set to correct duplex mode and match it with other equipment.

 

Using cordless phones? Replace your 2.4GHz cordless phones with either a 900Mhz or 5.8GHz style so they won’t interfere.

 

Use Wi-Fi sharing on a PlayBook? It’s important to switch off AP Isolation if your router has it. Mine has it on by default

 

Custom firewall rules can be fun, try to allow default and slowly make changes and take notes on what you enable or disable.

Re: Speed up BlackBerry Wi-Fi connections a knottyrope tip

(1) You should never hide SSID --- hiding SSID is a violation of  the 802.11 spec.

(2) The 802.11n spec stated that router should have a default 20 MHz narrow channel --- some older 802.11n router incorrectly default to wide channels.

(3) You should stick with auto channel hopping.  Your wifi router is smart enough to read your local airspace.  Your neighbour can buy a new router tomorrow and use the same wifi channel as you picked yesterday.

(4) QoS should be leave on.  It's part of the newer specs.

(5) wifi routers in the last 6-7 years all have hardware accelerated AES encryption --- which means that you should use WPA2/AES.  Your wifi router DON'T have hardware acceleration for WEP or WPA/TKIP encryption --- which means that your router's throughput is actually going to be slower using the older encryption methods.

Re: Speed up BlackBerry Wi-Fi connections a knottyrope tip

Thanks for the excellent tips Knotty.

 

I would like to add one more to the tips although not strictly a speed issue. As playbookers very often use wifi sharing it's important to switch off AP Isolation if your router has it. Mine has it on by default and it took some head scratching to get wifi sharing to work. 

 

 I agree, manual channel selection is indeed more reliable as neighbours generally don't change channels and the use of INSSIDER on pc or mac will give a good idea of what the neighbours are using. Mine never auto swaps properly and used to sit right in the same channel as two neighbours.

(4) QoS should be leave on.  It's part of the newer specs. This may be true but so many have older routers that come here for help. User can still revert back if they want to.

 

(5) wifi routers in the last 6-7 years all have hardware accelerated AES encryption --- which means that you should use WPA2/AES.  Your wifi router DON'T have hardware acceleration for WEP or WPA/TKIP encryption --- which means that your router's throughput is actually going to be slower using the older encryption methods. Agreed


Thanks for contributing. I can see this thread will be helpful and look forward to more good info.

Re: Speed up BlackBerry Wi-Fi connections a knottyrope tip

Very timely article Knotty. I just installed a new dual band router (DLink DIR 815)yesterday. And today I just changed the settings again. What a difference in speed, quite noticeable.

AP isolation is a fun one to figure out when file sharing, thanks for the reminder.

I completely disagree with you --- if you are going to start a thread to help people, you might as well help people the correct way, don't even give them the option to make incorrect choices.

 

SSID --- you should keep yelling the fact that it is a spec violation to hide the SSID, that it is not a security feature to hide your SSID to make yourself safer and that it will cause connection problems with other devices who respect the wifi spec.

 

The vast majority of the time, auto channel hopping will be a lot better than the end user picking channel 1 or 6 or 11.  You are starting a thread to help people, don't give them the incorrect information --- just becasue your specific router, specific router firmware and specific neighbour geographic situation doesn't work for you.  I live in a high rise condo with at least 20 wifi networks near me --- picking a specific channel is inappropriate.  You are trying to give general advice, don't give them a false sense of security by picking channel 11.

 

With respect to older wifi routers --- just give them this advice.  If your wifi n router has a firmware before Nov 2009 --- then stick to g only because you have a draft n device and will cause problems that are hard to solve if you try to connect with n speed settings.

 

You are starting a thread to give general advice --- and the most basic general advice is what my comments were.

Re: Speed up BlackBerry Wi-Fi connections a knottyrope tip

Respected or not --- the way he wrote his solution is very far from perfect.

 

The following thread from crackberry is a much simpler solution.

 

http://forums.crackberry.com/blackberry-playbook-f222/music-gateway-2-slows-playbook-down-terribly-7...

 

You update your router firmware, start off with the most basic settings and then change ONE setting at ONE time to isolate your problems.  99% of the time you don't need to change MTU settings.

Janetsa, whatever truth may be in your posts, your lack of diplomacy renders it valueless.
