I live in a high rise apartment and my router is on channel 1 and other tenants are on cnannel 6 or channel 11.I have installed InSsider on my computer and according to the graph the channel one is riding around 47-51 khz which is better than everyone else.Do I need to change my router to a higher channel to get the best reception for my Wi-Fi internet?

View 3 Replies View RelatedMy apartment complex offers free wifi but it is always unreliable, sometimes it is slow and I can't load pages. Often it says my signal is good or excellent and I still have problems. I'm pretty sure its not just my laptop because when I am home where we have our own network and my connection is great there. I have looked around on the internet for solutions and have not really found anything. All solutions say to do something to the router and I do not have access to it. I saw these things called usb wireless network adapters. Would they be able to increase my wifi connection?

My visually impaired friend purchase a new laptop...an Asus X73E-BH51 17.3" Laptop with 2nd Gen Intel Core i5-2430M with Turbo Boost 2.0 8GB DDR3 640GB HDD. She is happy with the purchase. However, the wireless signal strength on her machine never seems to go higher than three bars, while on my laptop (a different make) sitting next to hers is up to five bars and working very quickly.

View 2 Replies View RelatedWe are looking into setting up wireless internet access for the whole complex.
1) We would have around 200 users at max (accounting for people to have more than one device or computer connected. Such as Xbox360 and whatnot). What speeds should we consider from a ISP.?
2) Should we get more than one ISP feed?
3) How many wireless access points should we get? (Ruffly we are looking at 5-6)
4) Where should the WAP's be placed around the complex? Considering the apartments are brick outside and inside regular wood frame/drywall construction type. Also should they be inside or outdoor WAP's.
5)What hardware should be considered? (switches, WAP's, ect...)

View 10 Replies View RelatedWe have recently implemented some QoS on our routers and i have noticed that the CPU usage has risen enormously as a result.
I checked the CPU Processes and found that the avg values are 50% usage. This seems rather high considering that only 75% of our edge routers have this feature enabled.
Our main router is a Cisco CISCO2911/K9 (revision 1.0) with 487424K/36864K bytes of memory. Our edge routers are either 2801 models or 881 models.
This is our first implementation of QoS and would like to ensure that it is working properly before implementing other QoS rules. Here is a copy of the config on the 2911 router:
class-map match-all Citrix
match protocol citrix
class-map match-all Print
match protocol printer
class-map match-all C-Coolingata
[ code]......
Here is the config on our edge routers:
class-map match-any Citrix
match access-group name Citrix-ACL
[code]....
As you can see we have different link speeds at different sites based on their size, location etc. How to be able to confirm that this config is correct?
I own a Dell XPS M1330 laptop (Windows 7 Home Premium 32 bit, service pack 1) that is about three and a half years old. I realize this Dell model has been discontinued. Work with me here. I STRONGLY believe after 6+ hours of personal troubleshooting that the laptop model is NOT the problem. I have lived at the same apartment complex the entire time I have owned this laptop. Up until a month ago when a new management company (the third one I’ve had) took over, I was able to use the free WiFi they offer at the office and the laundry room without one single speck of a problem weekly for YEARS. Suddenly I am getting: Unidentified Network: No Internet Connection with a public park bench (which it is a public network, I suppose) and a “!” over my perfect five bar signal. Therefore, we can rule out signal strength as the problem. I have a Dell Wireless 1395 WLAN Mino-Card, the card that came pre-installed with the laptop when I bought it brand new. Also, I know the Dell Wireless Card WLAN Utility is installed on this computer but I’ve always used Windows Network and Sharing Center to control the WiFi network I am connected to. I saw something somewhere about this maybe being the problem but since I’ve never used it I don’t think it has anything to do with my problem…
Talk about the router will be brief as it is my apartment complex they will not allow me access to the router so I know virtually nothing other than it is a Cisco wireless router, there are three office computers connected to it that run the internet just fine, and DCHP is enabled on both my laptop and the router (I may or may not have snuck in against their wishes to figure this one out…).
Also noteworthy are two things. One: I can connect to about a dozen other public WiFi networks around the city malls, coffee shops, bookstores, the college campuses, ECT. So connecting to WiFi is not the problem, this WiFi network specifically is (AKA. My NIC is NOT dead). I can also connect to my boyfriend’s private network at his house. The second thing worth noting is that once, I got the manager to cave and re-set the router for me. It connected! I re-started my computer and it still connected! I took my laptop back to my apartment, brought it back re-booted an hour late and it still connected! The next morning; back to the same old annoying problem. I asked him if they did ANYTHING with the computers at night and he said no.
As I stated, I have 6+ hours of troubleshooting pre-done on this problem. I have tried what I am able to with no access to the router (okay, maybe I snuck in and did a couple more things…) including:
Re-start laptop.
Re-start router.
Disable all firewalls/virus protection programs/ect.
Connect to the internet in Safe Mode.
Disable Bonjour.
Uninstall wireless card/re-install wireless card/un-install drivers/re-install drivers/update drivers.
Reset the TCP/IP stack.

My internet comes in at one end of the apartment and then needs to travel about 60 feet and through three walls to get to the other end. Currently, the signal makes it about 25 feet through one wall and then fades. Should I use two extenders?

View 5 Replies View RelatedI recently moved into a new apartment complex where Internet is included with the rent, meaning that I do not have a personal Internet connection. Instead, the apartment company has a general connection along with a router on each floor of the complex. They then wire out from that connection to an ethernet port in each apartment. Because of that, calling the Internet company doesn't work because they can only tell me that the router on my floor is getting an Internet connection (and unfortunately my apartment is too far away from that router to have signal strength to use it for wireless). Most tenants plug their personal routers into the ethernet ports and use them for wireless connection within their apartments.
When I try to plug my router in, I cannot connect. I get an error message saying that there is no Internet connection. When I plug my Mac directly into the ethernet port, I still get no Internet connection. I've even tried plugging my netbook (PC) in, and get nothing. I have tried network diagnostics, I have used multiple ethernet cables, nothing. The previous tenant apparently plugged her router into the same ethernet jack I am using and had no problems. She has been gone for a few months, and now I cannot connect.

View 1 Replies View RelatedI have an XPS 8100 and have been very satisfied for the most part, but have had a persistent problem with the wireless card, the Atheros DW1525 WLAN PCIe Card. The wireless signal swings wildly between 3 bars and 5 bars - and the computer is close to the router. The card only weakly picks up other signals and it is often weak and spotty. I compared with my Dell Inspiron 13 (which has an Intel wireless N card), and it is literally 5x as fast on speed tests, picks up a lot of other signals, and is always 5 bars.
I tried to reinstall the Atheros drivers from the Dell support site, and that seemed to do the trick for a while.... the card was picking up as many signals as my notebook and at the same strength and speed. But after a Windows Update, the problem returned. I tried to reinstall the drivers again but got blue screen errors when I attempted to install Atheros' drivers... I spoke to a Dell tech, did a full factory image restore, and while I'm not getting blue screens now, the signal continues to be weak and spotty. I have Windows 7 64 bit..

Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today. On the dashboard of our asa 5510 the "outside interface" traffic usage is running constantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.
View 6 Replies View RelatedWe installed a solution with 2 Cisco 2801, BGP multihomed failover.
1) The router which is currently getting all the traffic gets to 55% to 60% of CPU usage when handling 40 SIP/RTP streams . This equals 10Mbit up/10Mbit down and it showed around 5800 packets TX and around 5800 packets RX, with a majority of them CEF switched. As those figures are way less than the performance figures published by Cisco, we wonder if we made any mistake in setting up our router, or if we can do something to improve the router setup.
2) Does it have an impact on router performance if we increase/decrease RTP packet size, thus increasing or decreasing the pps relative to the consumed bandwidth?
3) If it is not possible to improve router configuration, we also wonder about possible replacement units for those routers. Would a 2901 do a good job? By how much would it rise the capacity? What other models would you recommend if we plan to rise the number of concurrent calls by a factor of 4 or even 8 times of what we have now (so up to 48000 pps and 80Mbit).
Here is what we tried:
- ip route-cache same-interface does not seem to improve anything
- ip flow ingress on or off makes no difference
- disabling the inbound ACL on fa0/0 seems to reduce load by 10%, although I don't understand why - a very high percentage is CPU interrupts, and ACLs are process switched, or not?
- we tried following the Cisco guide for high CPU due to high interrupts, with no success
Here are some usage statistics:
The graphs that we plot via SNMP show a propotional growth/increase of CPU and bandwidth (and thus pps) At the highest loads, we had a bit more than 55% CPU utilization with more than 50% interrupt CPU.
CPU utilization for five seconds: 36%/30%; one minute: 30%; five minutes: 30%

My wireless connection says i have full bars of signal. When I do a speed test, i get 500-600 kb/s download. Which is what I used to get. However, after I re-installed my wireless adapter's card, the wna3100 netgear, it became extremely slow.
Pages would load slow, I could no longer play League of Legends properly because the ping is too high. Also, I used to have crossfire graphics cards running and the internet was fine, but after reinstallation, I thought I'd turn it off because that's how I fixed it before. But now, even with just one graphics card running, the internet is extremely slow.

View 2 Replies View RelatedI recently got a Netgear WNDR3400 Dual Band Wireless Router. When I first installing it everything seemed to run great, download was about 1.5 Mbps and a good ping, 20-70 for gaming. This lasted about a day. While the download does vary due to the service provider, my ping however has suddenly increased to a constant 200-400. This is happening on my Laptop, X-Box 360, and PS3.I have tested both wired and wireless connections from the router and used both the 2.64Ghz and 5Ghz frequency and I still have the same issue. I have then done a wired connection straight into the modem and my ping returns to the 20-70. My Router is less than 3 ft from all systems. I live in a barracks so there are multiple wireless signals floating about. However no one else seems to have any issues with there ping when using a wireless router and there only 1 room above me. I have changed channels on both frequency's, enabled and disabled NAT Filtering, decreased and increased the MTU size within the WAN settings, reset the router to factory defaults, ensured I have the proper firmware, and proper software for my laptop.

View 2 Replies View RelatedWhen using this laptop (Toshiba Satellite C660D-1GD) on the forum it seemed unusually laggy when changing pages, whereas when using my Toshiba Satellite L450D it is always more positive.Decided to do some ping tests via the cmd prompt (after checking the error count via telnet) and they were in the hundreds.The L450D ping tests are spot on so I know it isn't the router (Billion Bipac 7800N)Been the usual route, totally uninstalled the wireless adaptor (Realtek RTL8188CE Wireless LAN 802.11n) including the Cisco elements, Eset and MBAM full scan and downloaded chipset drivers. Even factory reset the router and deleted the wireless profile including reg entries as a last resort.After each of those operations (other than reinstalling the wireless adaptor) the latency would be spot on and continued to be after an immediate reboot, but logging on a couple of hours later or the following morning, they would be very high again.After reinstalling the wireless adaptor for the second time, on a hunch I removed the Ethernet cable and run another test. The latency came in high but when I re-ran the test wired, they were spot on.
Phoned up KnowHow techs and read off the numbers who then put me onto 2nd level tech. He remotely connected and ran a couple of ping -n 50 tests as well as a tracert but was unable to replicate the results I was gettiing. As nothing was broken (for him), nothing to fix but to phone again if it continued.I rebooted after the phone call and got the high latency straight off. I wondered, as the latency returned to normal after certain operations I'd done, whether the remote connection had the same effect.Having been on the phone for 55mins, I'd had enough.These are two tests I've recorded from today which are together in one Wordpad doc, so you'll be able to see what I mean. Ctrl+C has been a bit erratic so they are the only ones I've been able to save. [code]
