Setting up the Linksys EA9300 Max-Stream AC4000 Tri-Band Wi-Fi Router
Setting up the Linksys EA9300 Max-Stream AC4000 Tri-Band Wi-Fi Router Setting up the Linksys EA9300 Max-Stream AC4000 Tri-Band Wi-Fi Router is made easy using the Smart Setup wizard which is embedded in the router's firmware and is available even if the router does not have an internet connection or the router is on factory default settings. Before you begin: Make sure you have a working internet connection. Power on your modem and connect an ethernet cable from the modem to the internet port of the router. NOTE: If you are replacing an existing router, make sure to disconnect and remove the old one. Connect the power adapter to the router and turn it ON. Wait until the Linksys logo light is solid. Step 1: Connect a wireless computer, tablet or smartphone to the default Wi-Fi network of your router. The wireless credentials are located on a label at the bottom of the device. NOTE: If you need to set up the router using a hardwired computer, connect your computer to one of the ethernet ports at the back of the router. Step 2: Launch a supported web browser and enter “linksyssmartwifi.com” in the Address bar then press [Enter]. NOTE: You can also enter “http://192.168.1.1” or “myrouter.local”. Step 3: Check the box beside I have read and accepted the License Terms for using this software. Then click Next to proceed. NOTE: Open the link to know the license terms and other information. If you prefer to manually set up the router, click on the Manual configuration link. -

Is Bob Sending Mixed Signals?
Is Bob Sending Mixed Signals? Michael Schliep Ian Kariniemi Nicholas Hopper University of Minnesota University of Minnesota University of Minnesota [email protected] [email protected] [email protected] ABSTRACT Demand for end-to-end secure messaging has been growing rapidly and companies have responded by releasing applications that imple- ment end-to-end secure messaging protocols. Signal and protocols based on Signal dominate the secure messaging applications. In this work we analyze conversational security properties provided by the Signal Android application against a variety of real world ad- versaries. We identify vulnerabilities that allow the Signal server to learn the contents of attachments, undetectably re-order and drop messages, and add and drop participants from group conversations. We then perform proof-of-concept attacks against the application to demonstrate the practicality of these vulnerabilities, and suggest mitigations that can detect our attacks. The main conclusion of our work is that we need to consider more than confidentiality and integrity of messages when designing future protocols. We also stress that protocols must protect against compromised servers and at a minimum implement a trust but verify model. 1 INTRODUCTION (a) Alice’s view of the conversa-(b) Bob’s view of the conversa- Recently many software developers and companies have been inte- tion. tion. grating end-to-end encrypted messaging protocols into their chat applications.

Network speed between a given system adapter and the network Router is determined by the slowest network device. If the Router is an N Router, then your adapter mode is set for G. The problem is likely your Intel AGN Adapter settings - it's Wireless Mode is likely set to G, B/G, or A/B/G, but the N Mode setting probably isn't Enabled, which overrides the other Wireless Modes. Prior to the procedures below, go to Linksys Support, look up your Router, then download the latest firmware update. If it's the same as what you have, then download that. Linksys Support Standard Procedure for any Linksys Router problem with speed or signal begins with flashing the firmware prior to adjusting any other settings. I've added settings for your Router to match your adapter since I have the same hardware. You can look for your Router's firmware update at Linksys Support Enter your Model # and go from there to get the firmware update. The following assumes you have a Linksys Single Band N Router; though these settings are from my Linksys WRT600N Dual-Band, the Admin Panel is the same, except for the extra 5ghz Band setup on mine. Just in case, I've also added the 5ghz settings. With these settings and the AGN or my Linksys WUSB600N DBN Adapter, I average better than 200mbps+, usually around 240 or 260mbps. The settings for the AGN adapter after these settings are matched for the Router settings.

Request for Reconsideration After Final Action
Under the Paperwork Reduction Act of 1995 no persons are required to respond to a collection of information unless it displays a valid OMB control number. PTO Form 1960 (Rev 10/2011) OMB No. 0651-0050 (Exp 09/20/2020) Request for Reconsideration after Final Action The table below presents the data as entered. Input Field Entered SERIAL NUMBER 87031396 LAW OFFICE ASSIGNED LAW OFFICE 116 MARK SECTION MARK https://tmng-al.uspto.gov/resting2/api/img/87031396/large LITERAL ELEMENT CRYPTTALK STANDARD CHARACTERS YES USPTO-GENERATED IMAGE YES MARK STATEMENT The mark consists of standard characters, without claim to any particular font style, size or color. ARGUMENT(S) In the Official Action, the Examiner has made final the refusal to register the "CRYPTTALK" mark on the Principal Register because of the "likelihood of confusion" of the mark with prior registered marks. Applicant respectfully disagrees and believes that the Examiner has failed to make a prima facie showing of likelihood of confusion. I. NO LIKELIHOOD OF CONFUSION WITH U.S. REGISTRATION NOS. 4,707,027 and 4,859,726 A. The term "CRYPT" is Not a Distinctive Mark. The Examiner does not discuss the possibility of the cited registrations being viewed by the relevant consumer as the term "CRIP" and instead suggests that the terms "CRYPT" and "CRIPT" are the only relevant words to compare. The Examiner goes on to conclude that "CRYPT" and "CRIPT" in the respective marks "appear similar and are phonetic equivalents." This alleged similarity has been made the basis of the Examiners refusal to register Applicant's mark.
